我正在使用CentOS 7，并希望运行“ virtualenv”命令。所以我尝试卸载并重新安装它。
[myuser@server ~]$ sudo pip uninstall virtualenv

Cannot uninstall 'virtualenv'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
[myuser@server ~]$ sudo pip install virtualenv

Requirement already satisfied: virtualenv in /usr/lib/python2.7/site-packages (15.1.0)
但是当我去实际运行它时，会告诉我它没有安装。
[myuser@server ~]$ virtualenv myenv
Traceback (most recent call last):
File "/usr/bin/virtualenv", line 2, in <module>
import virtualenv
ModuleNotFoundError: No module named 'virtualenv'
WTF？

您只需删除virtualenv rm -r ./your_venv，然后创建一个新的python3 -m virtualenv your_venv并激活此source ./your_venv/bin/activate。现在您处于分离的环境中。例如，在这种状态下，您可以安装库pip install -r ./requirements.txt。这些库将仅安装在您的环境内部，而不是全局。

尝试python -m virtualenv myenv。 -m标志表示模块。使用此命令，您明确地告诉python将模块virtualenv作为脚本运行。
