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.
```
```
Install Options:
--no-clean Don't clean up build directories.
-r, --requirement Install from the given requirements file. This
option can be used multiple times.
-c, --constraint Constrain versions using the given constraints
file. This option can be used multiple times.
--no-deps Don't install package dependencies.
--pre Include pre-release and development versions. By
default, pip only finds stable versions.
-e, --editable <path/url> Install a project in editable mode (i.e.
setuptools "develop mode") from a local project
path or a VCS url.
-t, --target Install packages into . By default this
will not replace existing files/folders in
. Use --upgrade to replace existing
packages in with new versions.
--platform Only use wheels compatible with .
Defaults to the platform of the running system.
--python-version
The Python interpreter version to use for wheel
and "Requires-Python" compatibility checks.
Defaults to a version derived from the running
interpreter. The version can be specified using
up to three dot-separated integers (e.g. "3" for
3.0.0, "3.7" for 3.7.0, or "3.7.3"). A major-
minor version can also be given as a string
without dots (e.g. "37" for 3.7.0).
--implementation
Only use wheels compatible with Python
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.
--abi Only use wheels compatible with Python 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.
--user Install to the Python user install directory for
your platform. Typically ~/.local/, or
%APPDATA%\Python on Windows. (See the Python
documentation for site.USER_BASE for full
details.)
--root Install everything relative to this alternate
root directory.
--prefix Installation prefix where lib, bin and other
top-level folders are placed
-b, --build 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.
--src Directory to check out editable projects into.
The default in a virtualenv is "/src". The default for global installs is
"/src".
-U, --upgrade Upgrade all specified packages to the newest
available version. The handling of dependencies
depends on the upgrade-strategy used.
--upgrade-strategy
Determines how dependency upgrading should be
handled [default: only-if-needed]. "eager" -
dependencies are upgraded regardless of whether
the currently installed version satisfies the
requirements of the upgraded package(s). "only-
if-needed" - are upgraded only when they do not
satisfy the requirements of the upgraded
package(s).
--force-reinstall Reinstall all packages even if they are already
up-to-date.
-I, --ignore-installed Ignore the installed packages, overwriting them.
This can break your system if the existing
package is of a different version or was
installed with a different package manager!
--ignore-requires-python Ignore the Requires-Python information.
--no-build-isolation Disable isolation when building a modern source
distribution. Build dependencies specified by
PEP 518 must be already installed if this option
is used.
--use-pep517 Use PEP 517 for building source distributions
(use --no-use-pep517 to force legacy behaviour).
--install-option 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 Extra global options to be supplied to the
setup.py call before the install command.
--compile Compile Python source files to bytecode
--no-compile Do not compile Python source files to bytecode
--no-warn-script-location Do not warn when installing scripts outside PATH
--no-warn-conflicts Do not warn about broken dependencies
--no-binary
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 (notice the colons), or one or more
package names with commas between them (no
colons). Note that some packages are tricky to
compile and may fail to install when this option
is used on them.
--only-binary
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.
--prefer-binary Prefer older binary packages over newer source
packages.
--require-hashes 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.
--progress-bar
Specify type of progress to be displayed
[off|on|ascii|pretty|emoji] (default: on)
Package Index Options:
-i, --index-url Base URL of the 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-index-url Extra URLs of package indexes to use in addition
to --index-url. Should follow the same rules as
--index-url.
--no-index Ignore package index (only looking at --find-
links URLs instead).
-f, --find-links If a URL or path to an html file, then parse for
links to archives such as sdist (.tar.gz) or
wheel (.whl) files. If a local path or file://
URL that's a directory, then look for archives
in the directory listing. Links to VCS project
URLs are not supported.
```
```
General Options:
-h, --help Show help.
--isolated Run pip in an isolated mode, ignoring
environment variables and user configuration.
-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. Option is additive, and can be
used up to 3 times (corresponding to WARNING,
ERROR, and CRITICAL logging levels).
--log Path to a verbose appending log.
--proxy Specify a proxy in the form
[user:passwd@]proxy.server:port.
--retries Maximum number of retries each connection should
attempt (default 5 times).
--timeout Set the socket timeout (default 15 seconds).
--exists-action Default action when a path already exists:
(s)witch, (i)gnore, (w)ipe, (b)ackup, (a)bort.
--trusted-host Mark this host or host:port pair as trusted,
even though it does not have valid or any HTTPS.
--cert Path to alternate CA bundle.
--client-cert Path to SSL client certificate, a single file
containing the private key and the certificate
in PEM format.
--cache-dir Store the cache data in .
--no-cache-dir Disable the cache.
--disable-pip-version-check
Don't periodically check PyPI to determine
whether a new version of pip is available for
download. Implied with --no-index.
--no-color Suppress colored output
--no-python-version-warning
Silence deprecation warnings for upcoming
unsupported Pythons.

## Install from requirements file
Set the version.
- `requirements.txt` for PyPI:
```
foo>=0.2
```
- `requirement.txt` for GitHub:
```
-e git+https://github.com/FooBar/baz.git@master
```
Then install from the file.
```sh
$ pip install -r requirements.txt
```
## Install using CLI
Or install the version directly. Note the quotes help to escape characters.
- Install from PyPI:
```sh
$ pip install 'foo>=0.2'
```
- Install from GitHub:
```
$ pip install -e git+https://github.com/FooBar/baz.git@master
```
You omit a version, though this can be dangerous for upgrading or setting up environments for import projects. If you omit a version, you'll get the latest.
```sh
$ pip install foo
```
But note that command has no version number requested. So if you run the command repeatedly, you won't ever get a new version, except on a fresh install.
