Question

我有一个用于django应用程序的python虚拟环境。我用......激活它。

source venv/bin/activate

有效，但是当我尝试运行pip install时，我得到了这个回溯......

那么为什么当我应该在venv中运行时，它会尝试在/ usr中安装一些东西？

添加了输出 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时我得到了这个......

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

检查which pip的输出，大多数人都没有安装pip。如果不是来自venv，请检查which python。如果它不是venv的python，你不在新的环境中 - 应该有一些错误。

如果只缺少pip，请尝试安装：

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

修改

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。它会持续到你deactivate为止。

python虚拟环境正在安装到/ usr / ...？
