If you use +multiple Python versions, you can run ``pip-compile`` as ``py -X.Y -m piptools +compile`` on Windows and ``pythonX.Y -m piptools compile`` on other systems. + +``pip-compile`` should be run from the same virtual environment as your +project so conditional dependencies that require a specific Python version, +or other environment markers, resolve relative to your project's +environment. + +**Note**: ensure you don't have ``requirements.txt`` if you compile +``setup.py`` or ``requirements.in`` from scratch, otherwise, it might +interfere. + +Requirements from ``setup.py`` +------------------------------ + +Suppose you have a Django project, and want to pin it for production. +If you have a ``setup.py`` with ``install_requires=['django']``, then run +``pip-compile`` without any arguments: + +.. code-block:: bash + + $ pip-compile + # + # This file is autogenerated by pip-compile + # To update, run: + # + # pip-compile + # + asgiref==3.2.3 + # via django + django==3.0.3 + # via my_django_project (setup.py) + pytz==2019.3 + # via django + sqlparse==0.3.0 + # via django + +``pip-compile`` will produce your ``requirements.txt``, with all the Django +dependencies (and all underlying dependencies) pinned. + +Without ``setup.py`` +-------------------- + +If you don't use ``setup.py`` (`it's easy to write one`_), you can create a +``requirements.in`` file to declare the Django dependency: + +.. code-block:: ini + + # requirements.in + django + +Now, run ``pip-compile requirements.in``: + +.. code-block:: bash + + $ pip-compile requirements.in + # + # This file is autogenerated by pip-compile + # To update, run: + # + # pip-compile requirements.in + # + asgiref==3.2.3 + # via django + django==3.0.3 + # via -r requirements.in + pytz==2019.3 + # via django + sqlparse==0.3.0 + # via django + +And it will produce your ``requirements.txt``, with all the Django dependencies +(and all underlying dependencies) pinned. + +.. _it's easy to write one: https://packaging.python.org/guides/distributing-packages-using-setuptools/#configuring-your-project + +Using hashes +------------ + +If you would like to use *Hash-Checking Mode* available in ``pip`` since +version 8.0, ``pip-compile`` offers ``--generate-hashes`` flag: + +.. code-block:: bash + + $ pip-compile --generate-hashes requirements.in + # + # This file is autogenerated by pip-compile + # To update, run: + # + # pip-compile --generate-hashes requirements.in + # + asgiref==3.2.3 \ + --hash=sha256:7e06d934a7718bf3975acbf87780ba678957b87c7adc056f13b6215d610695a0 \ + --hash=sha256:ea448f92fc35a0ef4b1508f53a04c4670255a3f33d22a81c8fc9c872036adbe5 \ + # via django + django==3.0.3 \ + --hash=sha256:2f1ba1db8648484dd5c238fb62504777b7ad090c81c5f1fd8d5eb5ec21b5f283 \ + --hash=sha256:c91c91a7ad6ef67a874a4f76f58ba534f9208412692a840e1d125eb5c279cb0a \ + # via -r requirements.in + pytz==2019.3 \ + --hash=sha256:1c557d7d0e871de1f5ccd5833f60fb2550652da6be2693c1e02300743d21500d \ + --hash=sha256:b02c06db6cf09c12dd25137e563b31700d3b80fcc4ad23abb7a315f2789819be \ + # via django + sqlparse==0.3.0 \ + --hash=sha256:40afe6b8d4b1117e7dff5504d7a8ce07d9a1b15aeeade8a2d10f130a834f8177 \ + --hash=sha256:7c3dca29c022744e95b547e867cee89f4fce4373f3549ccd8797d8eb52cdb873 \ + # via django + +Updating requirements +--------------------- + +To update all packages, periodically re-run ``pip-compile --upgrade``. + +To update a specific package to the latest or a specific version use the +``--upgrade-package`` or ``-P`` flag: + +.. code-block:: bash + + # only update the django package + $ pip-compile --upgrade-package django + + # update both the django and requests packages + $ pip-compile --upgrade-package django --upgrade-package requests + + # update the django package to the latest, and requests to v2.0.0 + $ pip-compile --upgrade-package django --upgrade-package requests==2.0.0 + +You can combine ``--upgrade`` and ``--upgrade-package`` in one command, to +provide constraints on the allowed upgrades. For example to upgrade all +packages whilst constraining requests to the latest version less than 3.0: + +.. code-block:: bash + + $ pip-compile --upgrade --upgrade-package 'requests<3.0' + +Output File +----------- + +To output the pinned requirements in a filename other than +``requirements.txt``, use ``--output-file``. This might be useful for compiling +multiple files, for example with different constraints on django to test a +library with both versions using `tox <https://tox.readthedocs.io/en/latest/>`__: + +.. code-block:: bash + + $ pip-compile --upgrade-package 'django<1.0' --output-file requirements-django0x.txt + $ pip-compile --upgrade-package 'django<2.0' --output-file requirements-django1x.txt + +Or to output to standard output, use ``--output-file=-``: + +.. code-block:: bash + + $ pip-compile --output-file=- > requirements.txt + $ pip-compile - --output-file=- < requirements.in > requirements.txt + +Forwarding options to ``pip`` +----------------------------- + +Any valid ``pip`` flags or arguments may be passed on with ``pip-compile``'s +``--pip-args`` option, e.g. + +.. code-block:: bash + + $ pip-compile requirements.in --pip-args '--retries 10 --timeout 30' + +Configuration +------------- + +You might be wrapping the ``pip-compile`` command in another script. To avoid +confusing consumers of your custom script you can override the update command +generated at the top of requirements files by setting the +``CUSTOM_COMPILE_COMMAND`` environment variable. + +.. code-block:: bash + + $ CUSTOM_COMPILE_COMMAND="./pipcompilewrapper" pip-compile requirements.in + # + # This file is autogenerated by pip-compile + # To update, run: + # + # ./pipcompilewrapper + # + asgiref==3.2.3 + # via django + django==3.0.3 + # via -r requirements.in + pytz==2019.3 + # via django + sqlparse==0.3.0 + # via django + +Workflow for layered requirements +--------------------------------- + +If you have different environments that you need to install different but +compatible packages for, then you can create layered requirements files and use +one layer to constrain the other. + +For example, if you have a Django project where you want the newest ``2.1`` +release in production and when developing you want to use the Django debug +toolbar, then you can create two ``*.in`` files, one for each layer: + +.. code-block:: ini + + # requirements.in + django<2.2 + +At the top of the development requirements ``dev-requirements.in`` you use ``-c +requirements.txt`` to constrain the dev requirements to packages already +selected for production in ``requirements.txt``. + +.. code-block:: ini + + # dev-requirements.in + -c requirements.txt + django-debug-toolbar + +First, compile ``requirements.txt`` as usual: + +.. code-block:: bash + + $ pip-compile + # + # This file is autogenerated by pip-compile + # To update, run: + # + # pip-compile + # + django==2.1.15 + # via -r requirements.in + pytz==2019.3 + # via django + + +Now compile the dev requirements and the ``requirements.txt`` file is used as +a constraint: + +.. code-block:: bash + + $ pip-compile dev-requirements.in + # + # This file is autogenerated by pip-compile + # To update, run: + # + # pip-compile dev-requirements.in + # + django-debug-toolbar==2.2 + # via -r dev-requirements.in + django==2.1.15 + # via + # -c requirements.txt + # django-debug-toolbar + pytz==2019.3 + # via + # -c requirements.txt + # django + sqlparse==0.3.0 + # via django-debug-toolbar + +As you can see above, even though a ``2.2`` release of Django is available, the +dev requirements only include a ``2.1`` version of Django because they were +constrained. Now both compiled requirements files can be installed safely in +the dev environment. + +To install requirements in production stage use: + +.. code-block:: bash + + $ pip-sync + +You can install requirements in development stage by: + +.. code-block:: bash + + $ pip-sync requirements.txt dev-requirements.txt + + +Version control integration +--------------------------- + +You might use ``pip-compile`` as a hook for the `pre-commit <https://github.com/pre-commit/pre-commit>`_. +See `pre-commit docs <https://pre-commit.com/>`_ for instructions. +Sample ``.pre-commit-config.yaml``: + +.. code-block:: yaml + + repos: + - repo: https://github.com/jazzband/pip-tools + rev: 5.0.0 + hooks: + - id: pip-compile + +You might want to customize ``pip-compile`` args by configuring ``args`` and/or ``files``, for example: + +.. code-block:: yaml + + repos: + - repo: https://github.com/jazzband/pip-tools + rev: 5.0.0 + hooks: + - id: pip-compile + files: ^requirements/production\.(in|txt)$ + args: [--index-url=https://example.com, requirements/production.in] + + +Example usage for ``pip-sync`` +============================== + +Now that you have a ``requirements.txt``, you can use ``pip-sync`` to update +your virtual environment to reflect exactly what's in there. This will +install/upgrade/uninstall everything necessary to match the +``requirements.txt`` contents. + +Run it with ``pip-sync`` or ``python -m piptools sync``. If you use multiple +Python versions, you can also run ``py -X.Y -m piptools sync`` on Windows and +``pythonX.Y -m piptools sync`` on other systems. + +``pip-sync`` must be installed into and run from the same virtual +environment as your project to identify which packages to install +or upgrade. + +**Be careful**: ``pip-sync`` is meant to be used only with a +``requirements.txt`` generated by ``pip-compile``. + +.. code-block:: bash + + $ pip-sync + Uninstalling flake8-2.4.1: + Successfully uninstalled flake8-2.4.1 + Collecting click==4.1 + Downloading click-4.1-py2.py3-none-any.whl (62kB) + 100% |................................| 65kB 1.8MB/s + Found existing installation: click 4.0 + Uninstalling click-4.0: + Successfully uninstalled click-4.0 + Successfully installed click-4.1 + +To sync multiple ``*.txt`` dependency lists, just pass them in via command +line arguments, e.g. + +.. code-block:: bash + + $ pip-sync dev-requirements.txt requirements.txt + +Passing in empty arguments would cause it to default to ``requirements.txt``. + +Any valid ``pip install`` flags or arguments may be passed with ``pip-sync``'s +``--pip-args`` option, e.g. + +.. code-block:: bash + + $ pip-sync requirements.txt --pip-args '--no-cache-dir --no-deps' + +If you use multiple Python versions, you can run ``pip-sync`` as +``py -X.Y -m piptools sync ...`` on Windows and +``pythonX.Y -m piptools sync ...`` on other systems. + +**Note**: ``pip-sync`` will not upgrade or uninstall packaging tools like +``setuptools``, ``pip``, or ``pip-tools`` itself. Use ``python -m pip install --upgrade`` +to upgrade those packages. + +Should I commit ``requirements.in`` and ``requirements.txt`` to source control? +=============================================================================== + +Generally, yes. If you want a reproducible environment installation available from your source control, +then yes, you should commit both ``requirements.in`` and ``requirements.txt`` to source control. + +Note that if you are deploying on multiple Python environments (read the section below), +then you must commit a seperate output file for each Python environment. +We suggest to use the ``{env}-requirements.txt`` format +(ex: ``win32-py2.7-requirements.txt``, ``macos-py3.6-requirements.txt``, etc.). + + +Cross-environment usage of ``requirements.in``/``requirements.txt`` and ``pip-compile`` +======================================================================================= + +The dependencies of a package can change depending on the Python environment in which it +is installed. Here, we define a Python environment as the combination of Operating +System, Python version (2.7, 3.6, etc.), and Python implementation (CPython, PyPy, +etc.). For an exact definition, refer to the possible combinations of `PEP 508 +environment markers`_. + +As the resulting ``requirements.txt`` can differ for each environment, users must +execute ``pip-compile`` **on each Python environment separately** to generate a +``requirements.txt`` valid for each said environment. The same ``requirements.in`` can +be used as the source file for all environments, using `PEP 508 environment markers`_ as +needed, the same way it would be done for regular ``pip`` cross-environment usage. + +If the generated ``requirements.txt`` remains exactly the same for all Python +environments, then it can be used across Python environments safely. **But** users +should be careful as any package update can introduce environment-dependant +dependencies, making any newly generated ``requirements.txt`` environment-dependant too. +As a general rule, it's advised that users should still always execute ``pip-compile`` +on each targeted Python environment to avoid issues. + +.. _PEP 508 environment markers: https://www.python.org/dev/peps/pep-0508/#environment-markers + +Other useful tools +================== + +- `pipdeptree`_ to print the dependency tree of the installed packages. +- ``requirements.in``/``requirements.txt`` syntax highlighting: + + * `requirements.txt.vim`_ for Vim. + * `Python extension for VS Code`_ for VS Code. + * `pip-requirements.el`_ for Emacs. + +.. _pipdeptree: https://github.com/naiquevin/pipdeptree +.. _requirements.txt.vim: https://github.com/raimon49/requirements.txt.vim +.. _Python extension for VS Code: https://marketplace.visualstudio.com/items?itemName=ms-python.python +.. _pip-requirements.el: https://github.com/Wilfred/pip-requirements.el + + +Deprecations +============ + +This section lists ``pip-tools`` features that are currently deprecated. + +- ``--index/--no-index`` command-line options, use instead + ``--emit-index-url/--no-emit-index-url`` (since 5.2.0). + +- In future versions, the ``--allow-unsafe`` behavior will be enabled by + default.
