如何解决使用pycharm设置pipenv时出现的安装错误？

Question

我尝试在Pycharm中使用pipenv，但在尝试设置它时出现错误。

我在macOS Catalina 10.15.5 (19F101)上

当我运行brew install pipenv时，我用自制软件安装了python3.8。实际上，我的机器上安装了两个Python3。Python3.7和Python3.8二进制文件，后者是在我安装pipenv时自动安装的。我在网上尝试了所有其他解决方案，但似乎都不能解决这个问题：

pipenv.patched.notpip._internal.exceptions.InstallationError: Command errored out with exit status 1: python setup.py egg_info

以下是我的问题的屏幕截图：

如“命令输出”部分所示：

通常，当我使用pycharm时，我喜欢使用preferences ->项目解释器下的内置机制，你可以手动搜索你想要安装的包，然后从那里开始安装。
