如何解决Pipenv 始终无法锁定并产生大量错误输出
由于某种原因，我最近在使用 pipenv 时遇到了问题。似乎每次我尝试从带有 pipenv install 的 Pipfile 创建/安装虚拟环境时，我都会收到一个 Locking Failed 错误，然后是很多输出错误消息。我一直在努力解决这个问题，更新 setuptools 和其他各种软件包，试图找出问题所在，但到目前为止我在网上找到的类似问题的解决方案没有运气。

非常感谢您对解决此问题的任何帮助。提前致谢！
解决方法
这也是我在 BigSur 更新中注意到的一点。尽管在 GitHub 上有一个活跃的问题，但暂时的解决方法是在尝试锁定 Pipfile 或安装任何软件包之前运行以下命令。注意：这仅在您运行此命令的终端中有效。
export SYSTEM_VERSION_COMPAT=1
这将允许向后兼容，并且可以通过在运行上面的导出命令之前和之后运行以下命令进行测试
