创建新虚拟环境时出现 virtualenv 错误

Question

当我想创建一个新的 python venv 时，我使用以下命令：

python -m virtualenv -p=D:\python_v2\versions\3.8.3\python.exe D:\python_v2\venvs\DataScience

自从我拿到新电脑以来，它工作得很好。

我已经安装了 python 和 virtualenv 模块，但是当我使用完全相同的命令时，出现以下错误：

如果有人知道有关此问题的任何信息，请帮助我。

这似乎是一个关于很长路径的错误（我通过在 Virtualenv 问题跟踪器中搜索“no dist info”发现了这个错误）。

C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.8_3.8.1008.0_x64__qbz5n2kfra8p0\lib\...结果太长了，看起来像。

除非您可以缩短路径，否则解决方法似乎是--seeder=pip在创建 virtualenv 时添加。
