问题描述

如何找到我的站点包目录的位置?

How do I find the location of my site-packages directory?

推荐答案

站点包目录有两种类型，全局和每个用户.

There are two types of site-packages directories, global and per user.

1. 全球站点包("dist-packages") 目录在运行时列在 sys.path 中:

1. Global site-packages ("dist-packages") directories are listed in sys.path when you run:

python -m site

要获得更简洁的列表，请运行 getsitepackagesPython 代码中的>站点模块":

For a more concise list run getsitepackages from the site module in Python code:

python -c 'import site; print(site.getsitepackages())'

注意: virtualenvs getsitepackages 不可用，不过，上面的 sys.path 将正确列出 virtualenv 的 site-packages 目录.在 Python 3 中，您可以使用 sysconfig 模块 代替:

Note: With virtualenvs getsitepackages is not available, sys.path from above will list the virtualenv's site-packages directory correctly, though. In Python 3, you may use the sysconfig module instead:

python3 -c 'import sysconfig; print(sysconfig.get_paths()["purelib"])'

每个用户 站点包目录 (PEP 370) 是 Python 安装本地包的地方:

The per user site-packages directory (PEP 370) is where Python installs your local packages:

python -m site --user-site

如果这指向一个不存在的目录，请检查 Python 的退出状态并查看 python -m site --help 以获得解释.

If this points to a non-existing directory check the exit status of Python and see python -m site --help for explanations.

提示: 运行 pip list --user 或 pip freeze --user 会为您提供每个用户的所有安装列表 站点包.

Hint: Running pip list --user or pip freeze --user gives you a list of all installed per user site-packages.

实用技巧

• .__path__ 可让您识别特定包的位置:(详情)

  ---

  Practical Tips

  • <package>.__path__ lets you identify the location(s) of a specific package: (details)

    $ python -c "import setuptools as _; print(_.__path__)"
    ['/usr/lib/python2.7/dist-packages/setuptools']
    

  • .__file__ 可让您识别特定模块的位置:(区别)

  • <module>.__file__ lets you identify the location of a specific module: (difference)

    $ python3 -c "import os as _; print(_.__file__)"
    /usr/lib/python3.6/os.py
    

  • 运行 pip show 以显示 Debian 风格的包信息:

  • Run pip show <package> to show Debian-style package information:

    $ pip show pytest
