我通过pip卸载了本地安装的pylint软件包及其依赖项，而其他软件包不需要这些依赖项，在这个过程中，我的系统(Manjaro Linux(上的pip似乎已经完全沉没，尤其是在卸载toml软件包时。
toml是pip show pylint报告的pylint的依赖项之一，当pip show toml报告没有包需要它时，我运行了pip uninstall toml，并错误地假设它是本地包，忘记在命令前面加上sudo，这导致了异常：
ERROR: Exception:

During handling of the above exception, another exception occurred:

然后我刚刚运行了sudo pip uninstall toml，它报告了成功。然而，所有后续尝试通过pip安装、卸载或升级任何软件包，无论当前是否在我的系统上，都会遇到以下错误：

pip freeze和pip list也报告了相同的错误。
toml实际上是一个主要的pip依赖项，但没有被报道吗？有没有人足够熟悉pip的架构，知道我如何清理我的安装？如果我可以通过删除操作系统所需的python脚本和库来避免破坏系统，那么我可以删除所有的pip包并尝试重置我的系统，但由于pip list/freeze和pip uninstall命令已经不起作用了，我不确定该怎么做。如果有任何帮助，我将不胜感激。
Pip确实需要toml作为读取项目构建工具需求的潜在手段，这些需求可以写在pyproject.toml文件中。因此，使用pip卸载toml本质上是使用它来卸载构建包的一个依赖项——这并不明智，根据评论，最简单的解决方案只是在系统级别上卸载并重新安装pip。
