Python之pip：Python语言中的pip的简介、安装、使用方法之详细攻略（二）

2、pip参数解释

Options

-r, --requirement <file>

Install from the given requirements file. This option can be used multiple times.

-c, --constraint <file>

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 <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.

--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 <dir>

Install everything relative to this alternate root directory.

--prefix <dir>

Installation prefix where lib, bin and other top-level folders are placed

-b, --build <dir>

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 <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 specified packages to the newest available version. The handling of dependencies depends on the upgrade-strategy used.

--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).

--force-reinstall

Reinstall all packages even if they are already up-to-date.

-I, --ignore-installed

Ignore the installed packages (reinstalling instead).

--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.

--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.

--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 <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, 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.

--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.

--no-clean

Don't clean up build directories).

--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 <progress_bar>

Specify type of progress to be displayed [on|ascii|off|pretty|emoji] (default: on)

-i, --index-url <url>

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-index-url <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 <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.

--process-dependency-links

Enable the processing of dependency links.
