执行pip安装时发生Git revparse头错误

Question

在尝试安装python包datatable时，出现以下错误：

(venv) PS C:\Users\MART\Documents\Environments\cyber_analytics> pip install --no-cache-dir datatable

    Complete output (2 lines):
    Command `git rev-parse HEAD` failed with code 128: fatal: not a git repository (or any of the parent directories): .git

我已经在我的机器上安装了git，并且已经开始使用repos了。不使用VPNgit命令在Powershell中工作正常。无论pip安装到venv还是常规pip安装，都会出现相同的错误。也从git bash得到相同的错误。不确定这是什么

Answer 1

您可以通过从Python 3.9.5切换到Python 3.8.x来解决这个问题，因为datatable包具有Python版本3.6-8.x的控制盘
