但是,当我尝试在venv上安装时,它确实有效.

这可能与$PYTHONPATH有关吗？

(我相信当我尝试在已经启动的项目上运行runserver时,这也会导致冲突.但如果这个问题没解决,我会留下另一个问题.)

解决方法

您首先需要 activate您的虚拟环境.

$source PATH_TO_ENV/bin/env
$pip install django

In a newly created virtualenv there will also be a activate shell script. For Windows systems,activation scripts are provided for the Command Prompt and Powershell.

On Posix systems,this resides in /ENV/bin/

除非你这样做,否则你使用的是系统python和系统库.这就是你看错的原因.

如果需要在系统范围内安装lib,则需要root访问权限：

$sudo pip install django
