如何在使用 python 3 创建虚拟环境时修复看似无休止的循环？

Question

Cmd 提示符重复显示运行 virtualenv with interpreter c:\users\di203179\appdata\local\programs\python\python37-32\python.exe 并且从不创建虚拟环境。

我已经尝试升级 pip 和 python，以及运行命令的变体 virtualenv mypython

virtualenv mypython

我希望创建一个名称跟在命令 virtualenv 之后的文件夹。

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，结果是：

Answer 1

可能您使用的 virtualenv 模块版本 16.6.1 导致了该错误，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。

Answer 2

virtualenv 更新到版本 16.0.2。尝试： pip install virtualenv --upgrade
