Options

Here is a list of all of the available options supported by this action.

packages

The packages to install. This option can replace the requirements input or editable input, but either this, the requirements option, or the editable option is required.

A list can be provided to specify multiple packages. This syntax is a little different because actions only support string inputs. Due to this, each individual package can have no whitespace except around it.

This option does not correspond to any additional command flags, as none are necessary.

Examples:

## Valid inputs
packages: package1         # python -m pip install package1
packages: package1==1.0.0  # python -m pip install package1==1.0.0

packages: package1 package2                # python -m pip install package1 package2
packages: package1==1.0.0 package2         # python -m pip install package1==1.0.0 package2
packages: package1==1.0.0 package2==1.2.3  # python -m pip install package1==1.0.0 package2==1.2.3

# python -m pip install package1
packages: |
  package1
# python -m pip install package1==1.0.0
packages: |
  package1==1.0.0
# python -m pip install package1 package2
packages: |
  package1
  package2
# python -m pip install package1==1.0.0 package2
packages: |
  package1==1.0.0
  package2
# python -m pip install package1==1.0.0 package2==1.2.3
packages: |
  package1==1.0.0
  package2==1.2.3

## Invalid inputs
packages: package1 == 1.0.0

packages: |
  package1 == 1.0.0

requirements

A requirements file to install from. This option can replace the packages input or editable input, but either this, the packages option, or the editable option is required.

The input value should be a valid requirements file to install from. It corresponds to the --requirement argument for pip. Any valid value for that argument will be valid for this option.

No special formatting is done with this input, so it won't be treated special. The value recieved from this input will be passed directly to pip.

Examples:

requirements: ''                    # python -m pip install package1
requirements: requirements.txt      # python -m pip install --requirement requirements.txt
requirements: src/requirements.txt  # python -m pip install --requirement src/requirements.txt

constriants

A constraints file to install from. This can be used to specify the versions of packages that are allowed to be installed. It does not do anything to actually install new packages.

The input should be a valid constraints file to use. It corresponds to the --constraint argument for pip. Any valid value for that argument will be valid for this option.

No special formatting is done with this input, so it won't be treated special. The value recieved from this input will be passed directly to pip.

Examples:

constraints: ''                   # python -m pip install package1
constraints: constraints.txt      # python -m pip install --constraint constraints.txt package1
constraints: src/constraints.txt  # python -m pip install --constraint src/constraints.txt package1

no-deps

Specify not to install package dependencies. This will cause only the packages specified to be installed, and none of their dependencies.

It corresponds to the --no-deps argument for pip.

It is a boolean input, so either true or false will work as inputs.

Examples:

no-deps: true   # python -m pip install --no-deps package1
no-deps: false  # python -m pip install package1

pre

Specify to install development or pre-release versions of packages. This will allow the latest version of the package to be isntalled rather than the stable version.

It corresponds to the --pre argument for pip.

It is a boolean input, so either true or false will work as inputs.

Examples:

pre: true   # python -m pip install --pre package1
pre: false  # python -m pip install package1

editable

Install a package in editable mode. This option can replace the packages input or requirements input, but either this, the packages option, or the requirements option is required.

The input should be a valid package to install. It corresponds to the --editable argument for pip. Any valid value for that argument will be valid for this option.

No special formatting is done with this input, so it won't be treated special. The value recieved from this input will be passed directly to pip.

Examples:

editable: ''                                              # python -m pip install package1
editable: path/to/SomeProject                             # python -m pip install --editable path/to/SomeProject
editable: git+http://repo/my_project.git#egg=SomeProject  # python -m pip install --editable git+http://repo/my_project.git#egg=SomeProject

platform

Only install packages compatible with a specific platform. This will default to the platform currently running.

The input should be a valid platform. It corresponds to the --platform argument for pip. Any valid value for that argument will be valid for this option.

No special formatting is done with this input, so it won't be treated special. The value recieved from this input will be passed directly to pip.

Examples:

platform: ''                         # python -m pip install package1
platform: linux_x86_64               # python -m pip install --platform linux_x86_64 package1
platform: linux_ubuntu_18_04_x86_64  # python -m pip install --platform linux_ubuntu_18_04_x86_64 package1

upgrade

Specify to upgrade packages. This will cause already installed packages to be upgraded if an upgrade is available.

It corresponds to the --upgrade argument for pip.

It is a boolean input, so either true or false will work as inputs.

Examples:

upgrade: true   # python -m pip install --upgrade package1
upgrade: false  # python -m pip install package1

extra

Specify additional arguments to pass to pip. These are extra options that may not be provided by independent inputs to this action.

It does not correspond to any pip arguments. The input is passed directly to pip without any formatting.

Examples:

extra: ''      # python -m pip install package1
extra: --user  # python -m pip install --user package1

Additional info

Here is just a little bit of additional information to explain some things that may not be trivial.

Python location

It is highly recommended that you use the setup-python action to install Python. This streamlines the process and makes sure that you have a valid Python installed and located.

This action will automatically detect if Python is installed in 1 of two ways. Firstly, it checks the pythonLocation environment variable. This is set by the setup-python action, and is a directory pointing to the Python installation.

Secondly, if the setup-python action is not used, the path will be checked for Python. If Python is found in the path environment variable, this action will use that version. Otherwise, an error is thrown.

Empty strings

Empty strings are used to signify no input. Github Actions only allow string key/value inputs, so inputs are always strings. Inputs that are not specified automatically return an empty string. Because of this, we use an empty string to signify an input has no value. For most options, this will cause the argument to not appear in the final command.
