$ pip install --help
Usage:
pip install [options] <requirement specifier> ...
pip install [options] -r <requirements file> ...
pip install [options] [-e] <vcs project url> ...
pip install [options] [-e] <local project path> ...
pip install [options] <archive url/path> ...
Description:
Install packages from:
- PyPI (and other indexes) using requirement specifiers.
- VCS project urls.
- Local project directories.
- Local or remote source archives.
pip also supports installing from "requirements files", which provide
an easy way to specify a whole environment to be installed.
See http://www.pip-installer.org for details on VCS url formats and
requirements files.
Install Options:
-e, --editable <path/url> Install a project in editable mode (i.e. setuptools "develop mode") from a local project path or
a VCS url.
-r, --requirement <file> Install from the given requirements file. This option can be used multiple times.
-b, --build <dir> Directory to unpack packages into and build in. The default in a virtualenv is "<venv
path>/build". The default for global installs is "<OS temp dir>/pip_build_<username>".
-t, --target <dir> Install packages into <dir>.
-d, --download <dir> Download packages into <dir> instead of installing them, regardless of what's already installed.
--download-cache <dir> Cache downloaded packages in <dir>.
--src <dir> 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".
-U, --upgrade Upgrade all packages to the newest available version. This process is recursive regardless of
whether a dependency is already satisfied.
--force-reinstall When upgrading, reinstall all packages even if they are already up-to-date.
-I, --ignore-installed Ignore the installed packages (reinstalling instead).
--no-deps Don't install package dependencies.
--no-install Download and unpack all packages, but don't actually install them.
--no-download Don't download any packages, just install the ones already downloaded (completes an install run
with --no-install).
--install-option <options> Extra arguments to be supplied to the setup.py install command (use like --install-option
="--install-scripts=/usr/local/bin"). Use multiple --install-option options to pass multiple
options to setup.py install. If you are using an option with a directory path, be sure to use
absolute path.
--global-option <options> Extra global options to be supplied to the setup.py call before the install command.
--user Install using the user scheme.
--egg Install as self contained egg file, like easy_install does.
--root <dir> Install everything relative to this alternate root directory.
--use-wheel Find and prefer wheel archives when searching indexes and find-links locations. Default to
accepting source archives.
--pre Include pre-release and development versions. By default, pip only finds stable versions.
--no-clean Don't clean up build directories.
Package Index Options:
-i, --index-url <url> Base URL of Python Package Index (default https://pypi.python.org/simple/).
--extra-index-url <url> Extra URLs of package indexes to use in addition to --index-url.
--no-index Ignore package index (only looking at --find-links URLs instead).
-f, --find-links <url> 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.
-M, --use-mirrors Use the PyPI mirrors as a fallback in case the main index is down.
--mirrors <url> Specific mirror URLs to query when --use-mirrors is used.
--allow-external <package> Allow the installation of externally hosted files
--allow-all-external Allow the installation of all externally hosted files
--no-allow-external Disallow the installation of all externally hosted files
--allow-insecure <package> Allow the installation of insecure and unverifiable files
--no-allow-insecure Disallow the installation of insecure and unverifiable files
General Options:
-h, --help Show help.
-v, --verbose Give more output. Option is additive, and can be used up to 3 times.
-V, --version Show version and exit.
-q, --quiet Give less output.
--log <file> Log file where a complete (maximum verbosity) record will be kept.
--proxy <proxy> Specify a proxy in the form [user:passwd@]proxy.server:port.
--timeout <sec> Set the socket timeout (default 15 seconds).
--exists-action <action> Default action when a path already exists: (s)witch, (i)gnore, (w)ipe, (b)ackup.
--cert <path> Path to alternate CA bundle.
