NAME
pip3-install - description of pip3 install command
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.
USAGE
python -m pip install [options] <requirement specifier> [package-index-options] ...
python -m pip install [options] -r <requirements file> [package-index-options] ...
python -m pip install [options] [-e] <vcs project url> ...
python -m pip install [options] [-e] <local project path> ...
python -m pip install [options] <archive url/path> ...
OPTIONS
-r, --requirement <file>
Install from the given requirements file. This option can be used multiple times.
(environment variable: PIP_REQUIREMENT)
-c, --constraint <file>
Constrain versions using the given constraints file. This option can be used multiple times.
(environment variable: PIP_CONSTRAINT)
--no-deps
Don't install package dependencies.
(environment variable: PIP_NO_DEPS, PIP_NO_DEPENDENCIES)
--pre Include pre-release and development versions. By default, pip only finds stable versions.
(environment variable: PIP_PRE)
-e, --editable <path/url>
Install a project in editable mode (i.e. setuptools "develop mode") from a local project path or a
VCS url.
(environment variable: PIP_EDITABLE)
--dry-run
Don't actually install anything, just print what would be. Can be used in combination with
--ignore-installed to 'resolve' the requirements.
(environment variable: PIP_DRY_RUN)
-t, --target <dir>
Install packages into <dir>. By default this will not replace existing files/folders in <dir>. Use
--upgrade to replace existing packages in <dir> with new versions.
(environment variable: PIP_TARGET)
--platform <platform>
Only use wheels compatible with <platform>. Defaults to the platform of the running system. Use
this option multiple times to specify multiple platforms supported by the target interpreter.
(environment variable: PIP_PLATFORM)
--python-version <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).
(environment variable: PIP_PYTHON_VERSION)
--implementation <implementation>
Only use 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.
(environment variable: PIP_IMPLEMENTATION)
--abi <abi>
Only use wheels compatible with Python abi <abi>, e.g. 'pypy_41'. If not specified, then the
current interpreter abi tag is used. Use this option multiple times to specify multiple abis
supported by the target interpreter. Generally you will need to specify --implementation,
--platform, and --python-version when using this option.
(environment variable: PIP_ABI)
--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.)
(environment variable: PIP_USER)
--root <dir>
Install everything relative to this alternate root directory.
(environment variable: PIP_ROOT)
--prefix <dir>
Installation prefix where lib, bin and other top-level folders are placed. Note that the resulting
installation may contain scripts and other resources which reference the Python interpreter of
pip, and not that of --prefix. See also the --python option if the intention is to install
packages into another (possibly pip-free) environment.
(environment variable: PIP_PREFIX)
--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".
(environment variable: PIP_SRC, PIP_SOURCE, PIP_SOURCE_DIR, PIP_SOURCE_DIRECTORY)
-U, --upgrade
Upgrade all specified packages to the newest available version. The handling of dependencies
depends on the upgrade-strategy used.
(environment variable: PIP_UPGRADE)
--upgrade-strategy <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).
(environment variable: PIP_UPGRADE_STRATEGY)
--force-reinstall
Reinstall all packages even if they are already up-to-date.
(environment variable: PIP_FORCE_REINSTALL)
-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!
(environment variable: PIP_IGNORE_INSTALLED)
--ignore-requires-python
Ignore the Requires-Python information.
(environment variable: PIP_IGNORE_REQUIRES_PYTHON)
--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.
(environment variable: PIP_NO_BUILD_ISOLATION)
--use-pep517
Use PEP 517 for building source distributions (use --no-use-pep517 to force legacy behaviour).
(environment variable: PIP_USE_PEP517)
--check-build-dependencies
Check the build dependencies when PEP517 is used.
(environment variable: PIP_CHECK_BUILD_DEPENDENCIES)
--break-system-packages
Allow pip to modify an EXTERNALLY-MANAGED Python installation
(environment variable: PIP_BREAK_SYSTEM_PACKAGES)
-C, --config-settings <settings>
Configuration settings to be passed to the PEP 517 build backend. Settings take the form
KEY=VALUE. Use multiple --config-settings options to pass multiple keys to the backend.
(environment variable: PIP_CONFIG_SETTINGS)
--global-option <options>
Extra global options to be supplied to the setup.py call before the install or bdist_wheel
command.
(environment variable: PIP_GLOBAL_OPTION)
--compile
Compile Python source files to bytecode
(environment variable: PIP_COMPILE)
--no-compile
Do not compile Python source files to bytecode
(environment variable: PIP_NO_COMPILE)
--no-warn-script-location
Do not warn when installing scripts outside PATH
(environment variable: PIP_NO_WARN_SCRIPT_LOCATION)
--no-warn-conflicts
Do not warn about broken dependencies
(environment variable: PIP_NO_WARN_CONFLICTS)
--no-binary <format_control>
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.
(environment variable: PIP_NO_BINARY)
--only-binary <format_control>
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.
(environment variable: PIP_ONLY_BINARY)
--prefer-binary
Prefer binary packages over source packages, even if the source packages are newer.
(environment variable: PIP_PREFER_BINARY)
--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.
(environment variable: PIP_REQUIRE_HASHES)
--progress-bar <progress_bar>
Specify whether the progress bar should be used [on, off, raw] (default: on)
(environment variable: PIP_PROGRESS_BAR)
--root-user-action <root_user_action>
Action if pip is run as a root user [warn, ignore] (default: warn)
(environment variable: PIP_ROOT_USER_ACTION)
--report <file>
Generate a JSON file describing what pip did to install the provided requirements. Can be used in
combination with --dry-run and --ignore-installed to 'resolve' the requirements. When - is used as
file name it writes to stdout. When writing to stdout, please combine with the --quiet option to
avoid mixing pip logging output with JSON output.
(environment variable: PIP_REPORT)
--no-clean
Don't clean up build directories.
(environment variable: PIP_NO_CLEAN)
