如何在 virtualenv 中添加到 PYTHONPATH 的路径 [英] How do I add a path to PYTHONPATH in virtualenv

问题描述

我正在尝试向 PYTHONPATH 环境变量添加路径，该路径仅在特定的 virtualenv 环境中可见.

I am trying to add a path to the PYTHONPATH environment variable, that would be only visible from a particular virtualenv environment.

我在 virtualenv 命令提示符下尝试了 SET PYTHONPATH=...，但这为整个环境设置了变量.

I tried SET PYTHONPATH=... under a virtualenv command prompt, but that sets the variable for the whole environment.

我如何做到这一点?

推荐答案

你通常可以通过 使用 .pth 文件.只需在您的 virtualenv 的 site-packages 文件夹中放置一个扩展名为 .pth 的文件(任何基本名称都有效)，例如lib\python2.7\site-packages，以包含包的目录的绝对路径作为其唯一内容.

You can usually avoid having to do anything with PYTHONPATH by using .pth files. Just put a file with a .pth extension (any basename works) in your virtualenv's site-packages folder, e.g. lib\python2.7\site-packages, with the absolute path to the directory containing your package as its only contents.
