问题描述
我正在docker容器中使用pipenv。我尝试安装软件包，发现安装成功（将其添加到Pipfile中），但是锁定始终失败。直到昨天一切都很好。这是错误：

删除Pipfile.lock并尝试安装软件包后，我得到了：

解决方法
这是我的调试说明。仍然不确定是哪个软件包导致了问题，但这似乎可以解决问题。
当您首次使用Pipenv版本pipenv install运行2020.8.13时遇到的错误。

如果您运行pip install -U pipenv，则似乎会更改importlib-metadata版本：
Installing collected packages: importlib-metadata
Attempting uninstall: importlib-metadata
Found existing installation: importlib-metadata 2.0.0
Uninstalling importlib-metadata-2.0.0:
Successfully uninstalled importlib-metadata-2.0.0
Successfully installed importlib-metadata-1.7.0
现在，如果您运行pipenv install -d --skip-lock，它将完成。似乎图书馆需要版本>= importlib-metadata 2.0。
当我固定以下依赖项时，它首先在运行pipenv lock时不起作用，但是，如果我删除了锁定文件（rm Pipenv.lock），则在运行pipenv lock时它起作用了再次。
virtualenv = "==20.0.31"
importlib-metadata = "==1.7.0"
尝试在安装软件包之前删除Pipefile.lock
