Python Beeware公文包Git SHA问题

Question

我试着教自己如何使用Python的蜂鸣器公文包包，尽管设置它有问题。我已经安装了pyenv，我的项目根目录中的本地python版本被设置为3.8.9。我在使用windows和Powershell

在PowerShell中，我创建了python虚拟环境，并通过pip安装了公文包。

我也安装了git，并将回购链接到github。

当我尝试运行“新建公文包”并查看提示时，我会收到以下回溯(对于powershell和gitbash)：

(我在下面的错误中删除了我的根目录)

Answer 1

不知道如何解决这个问题，但我卸载了GitVersion2.37.1并安装了GitVersion2.30.2，使用GitBash创建了一个新环境，并安装了一个公文包。

似乎已经解决了这个问题。
