pip [options] <requirement specifier> [package-index-options] ... pip [options] -r <requirements file> [package-index-options] ... pip [options] <vcs project url> ... pip [options] <local project path> ... pip [options] <archive url/path> ...
Download packages from:
- PyPI (and other indexes) using requirement specifiers.
- VCS project urls.
- Local project directories.
- Local or remote source archives.
pip also supports downloading from “requirements files”, which provide an easy way to specify a whole environment to be downloaded.
pip download does the same resolution and downloading as
pip install, but instead of installing the dependencies, it collects the downloaded distributions into the directory provided (defaulting to the current directory). This directory can later be passed as the value to
pip install --find-links to facilitate offline or locked down package installation.
pip download with the
--abi options provides the ability to fetch dependencies for an interpreter and system other than the ones that pip is running on.
--no-deps is required when using any of these options. It is important to note that these options all default to the current system/interpreter, and not to the most restrictive constraints (e.g. platform any, abi none, etc). To avoid fetching dependencies that happen to match the constraint of the current interpreter (but not your target one), it is recommended to specify all of these options if you are specifying one of them. Generic dependencies (e.g. universal wheels, or dependencies with no platform, abi, or implementation constraints) will still match an over- constrained download requirement.
Constrain versions using the given constraints file. This option can be used multiple times.
Install from the given requirements file. This option can be used multiple times.
Directory to unpack packages into and build in. Note that an initial build still takes place in a temporary directory. The location of temporary directories can be controlled by setting the TMPDIR environment variable (TEMP on Windows) appropriately. When passed, build directories are not cleaned in case of failures.
Don’t install package dependencies.
Extra global options to be supplied to the setup.py call before the install command.
Do not use binary packages. Can be supplied multiple times, and each time adds to the existing value. Accepts either :all: to disable all binary packages, :none: to empty the set, or one or more package names with commas between them. Note that some packages are tricky to compile and may fail to install when this option is used on them.
Do not use source packages. Can be supplied multiple times, and each time adds to the existing value. Accepts either :all: to disable all source packages, :none: to empty the set, or one or more package names with commas between them. Packages without binary distributions will fail to install when this option is used on them.
Directory to check out editable projects into. The default in a virtualenv is “<venv path>/src”. The default for global installs is “<current dir>/src”.
Include pre-release and development versions. By default, pip only finds stable versions.
Don’t clean up build directories).
Require a hash to check each requirement against, for repeatable installs. This option is implied when any package in a requirements file has a –hash option.
Specify type of progress to be displayed [on|ascii|off|pretty|emoji] (default: on)
Disable isolation when building a modern source distribution. Build dependencies specified by PEP 518 must be already installed if this option is used.
Download packages into <dir>.
Only download wheels compatible with <platform>. Defaults to the platform of the running system.
Only download wheels compatible with Python interpreter version <version>. If not specified, then the current system interpreter minor version is used. A major version (e.g. ‘2’) can be specified to match all minor revs of that major version. A minor version (e.g. ’34’) can also be specified.
Only download wheels compatible with Python implementation <implementation>, e.g. ‘pp’, ‘jy’, ‘cp’, or ‘ip’. If not specified, then the current interpreter implementation is used. Use ‘py’ to force implementation-agnostic wheels.
Only download wheels compatible with Python abi <abi>, e.g. ‘pypy_41’. If not specified, then the current interpreter abi tag is used. Generally you will need to specify –implementation, –platform, and –python-version when using this option.
Base URL of Python Package Index (default https://pypi.org/simple). This should point to a repository compliant with PEP 503 (the simple repository API) or a local directory laid out in the same format.
Extra URLs of package indexes to use in addition to –index-url. Should follow the same rules as –index-url.
Ignore package index (only looking at –find-links URLs instead).
If a url or path to an html file, then parse for links to archives. If a local path or
file:// url that’s a directory, then look for archives in the directory listing.
Enable the processing of dependency links.
Download a package and all of its dependencies
$ pip download SomePackage $ pip download -d . SomePackage # equivalent to above $ pip download --no-index --find-links=/tmp/wheelhouse -d /tmp/otherwheelhouse SomePackage
Download a package and all of its dependencies with OSX specific interpreter constraints.
This forces OSX 10.10 or lower compatibility. Since OSX deps are forward compatible, this will also match
macosx-10_8_intel, etc. It will also match deps with platform
any. Also force the interpreter version to
27 (or more generic, i.e.
2) and implementation to
cp (or more generic, i.e.
$ pip download \ --only-binary=:all: \ --platform macosx-10_10_x86_64 \ --python-version 27 \ --implementation cp \ SomePackage
Download a package and its dependencies with linux specific constraints.
Force the interpreter to be any minor version of py3k, and only accept
none as the abi.
$ pip download \ --only-binary=:all: \ --platform linux_x86_64 \ --python-version 3 \ --implementation cp \ --abi cp34m \ SomePackage
Force platform, implementation, and abi agnostic deps.
$ pip download \ --only-binary=:all: \ --platform any \ --python-version 3 \ --implementation py \ --abi none \ SomePackage
Even when overconstrained, this will still correctly fetch the pip universal wheel.
$ pip download \ --only-binary=:all: \ --platform linux_x86_64 \ --python-version 33 \ --implementation cp \ --abi cp34m \ pip>=8 $ ls pip-8.1.1-py2.py3-none-any.whl pip-8.1.1-py2.py3-none-any.whl
