无法从虚拟环境，PowerShell，Windows 10运行点子

Question

不使用虚拟环境时，

“ pip”可以从powershell cli正常工作。当虚拟环境启动时，我得到Fatal error in launcher: Unable to create process using '"c:\py\venvs\x1\scripts\python.exe" "C:\py\venvs\x1\Scripts\pip.exe"'

有类似问题的各种报道。我已经在虚拟环境中重新安装了pip，并且同时使用了python -m venv和virtualenv。以下是使用-m venv时遇到的错误。

我的问题是如何使它工作，以便pip可以在虚拟环境中运行和安装软件包？

部分问题是区分大小写，此处未显示，我尝试创建指向“脚本”的“脚本”的符号链接，这样做时，我收到“没有名为pip的模块”消息。

在最后一行中，当它失败时，诊断程序正在谈论系统级（我的appdata文件夹）中的点而不是虚拟环境。

我的家用计算机上的3.6.6和3.8.1都会发生这种情况。在我的工作机上不会发生。
