pip在哪里安装带有虚拟环境的软件包? [英] Where does pip install packages with a virtual environment?

问题描述

情况:我已经创建了一个虚拟环境，并使用显式路径来运行pip(无需采购activate).它是将软件包安装在全局dist-packages中还是将它们安装在虚拟环境的site-packages中.

Situation: I have created a virtual environment and use an explicit path to run pip (without sourcing activate). Does it install packages in the global dist-packages or does it install them in the virtual environment's site-packages.

详细信息: 正如 pip在何处安装其软件包?所述，pip在与虚拟环境一起使用时.根据我的经验，当我激活virtualenv时，这是正确的.我有一个现有的bash脚本，无需激活virtualenv即可直接路径到pip可执行文件.这是否仍将软件包安装在virtualenv的站点软件包中?还是将它们安装在/local/lib/<python-version>/dist-packages中?

Details: As Where does pip install its packages? explains, pip installs packages in <virtualenv_name>/lib/<python_ver>/site-packages when used with a virtual environment. From my experience, this is true when I activate the virtualenv. I have an existing bash script that paths directly to the pip executable without activating the virtualenv. Does this still install packages in the virtualenv's site-packages? Or does it install them in /local/lib/<python-version>/dist-packages?

注意:我正在使用Ubuntu 16.04

推荐答案

这很大程度上取决于哪个版本(不是语义版本，而是……的具有多个版本")创建venv时安装的pip)脚本正在使用的pip及其配置(可能包括您的环境).

This very much depends on which version (not in the semantic version sense, but of the having-multiple-"versions" of pip installed when you create a venv) of pip your script is using, as well as its configuration (including possibly your environment).

假设您的脚本中有一行

/some/path/to/pip install <some package>

，并假设该pip已安装至少一个软件包，则可以使用

and assuming that that pip has installed at least one package, you can use

/some/path/to/pip show <that package>

，它将为您提供如下输出:

and it'll give you output that looks like:
