pipenv install --dev 安装开发依赖时报错 THESE PACKAGES DO NOT MATCH THE HASHES FROM THE REQUIREMENTS FILE

以下是主要错误，之前clone其他项目并安装开发依赖时在try again时是成功的，这次不行

错误原因是 Pipenv 缓存的包文件 hash 和 Pipfile.lock 里的 hash 不对应，具体原因我还不清楚。临时的解决办法是使用下面的安装命令（跳过版本锁定）：

$ pipenv install coverage --skip-lock

和这个帖子相关。另外，下次发帖请注意代码块排版。

好的，谢谢。
