使用python 3创建虚拟环境时如何修复看似无限的循环？

Question

Cmd 提示说virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe重复运行并且从不创建虚拟环境。

我试过升级 pip 和 python，并运行命令的变体 virtualenv mypython

virtualenv mypython

我希望创建一个名称跟随命令的文件夹virtualenv。

但实际结果是这样的：

Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe
Running virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe

直到我点击ctrl-c它给出了这个：

Answer 1

可能您正在使用导致该错误的 virtualenv 模块的 16.6.1 版，请尝试使用以下代码安装 16.6.0：

 pip install virtualenv==16.6.0

然后再次尝试创建虚拟环境。
