第一次看到这个问题......不确定是什么问题。

尝试使用python2和新的virtualenv，同样的问题。我记得在不同的virtualevn上安装pytz并没有遇到这个问题。

Answer 1

在python3中没有使用virtualenv，但是在python2中，使用pip时它不需要sudo。猜你可能需要使用pip3

Answer 2

嗯，奇怪的是，该文件夹包含setup.cfg，其中包含以下内容

[install]
prefix=

如果我删除了setup.cfg文件，则pip install工作正常......

Answer 3

我能想到的最简单的解决方案是以管理员身份运行CMD提示。

virutalenv中的Python3 pip安装给出了权限错误
