I have a python virtual env that I am using for a django application. I activate it with...

source venv/bin/activate

那行得通，但是我在尝试运行 pip install 时得到了这个回溯...

that works, but then I get this traceback when trying to run a pip install...

那么当我应该在 venv 中运行时，它为什么要尝试在/usr 中安装某些东西?

So why would it be trying to install something in /usr when I am supposed to be running in the venv?

添加了输出virtualenv venv

added the output of virtualenv venv

New python executable in venv/bin/python
Installing setuptools, pip...done.

当我使用 source 启动那个 venv 并运行哪个 python 我得到这个...

and when I use source to start that venv and run which python I get this...

/home/user/Desktop/test/venv/bin/python

推荐答案

检查which pip 的输出，最有可能的 pip 没有安装.如果它不是来自 venv 的 pip 还要检查 which python.如果不是 venv 的 python，则说明您不在新环境中 - 应该有一些错误.

Check the output of which pip, most likly pip is not installed. If it is not pip from venv also check which python. If it is not venv's python, your are not in the new env - there should be some errors.

如果只缺少 pip 尝试安装:

If only pip is missing try to install with:

curl --silent --show-error --retry 5 https://bootstrap.pypa.io/get-pip.py | python

编辑

Virualenv 仅适用于当前的 shell 会话.要在另一个会话/终端/窗口中使用，您必须再次激活它.它会一直存在，直到您停用它.

Virualenv is only for current shell session. To use in another session/terminal/window you must activate it again. It persists until you deactivate it.
