如果遇到这个问题，可以尝试直接使用 pip uninstall -y 命令进行卸载，并且注意不要手动修改相关安装文件，以免出现卸载问题。在使用 Python 进行开发时，我们难免会遇到需要卸载某些已经安装的库的情况。然后，找到对应的安装包，使用系统命令行或者文件管理器删除对应的安装包文件夹即可。接下来，可以通过系统命令行或者文件管理器找到对应的安装包文件夹，然后将其手动删除即可。参数，表示自动确认卸载操作，可以避免出现提示，这在大多数情况下是可行的。首先，需要确定你安装的库的名称及版本号，可以通过。

本篇文章默认你已经有了阿里云服务器，并且是以Ubuntu系统为例进行讲解的，是一个入门教程，最终实现的功能仅仅是可以通过外网ip来实现对网站的访问，未来可能会有更深入的文章，但是也说不准，这是我在奋战了8个小时之后终于实现了我想达到的目标后进行的技术总结，主要还是怕时间久了，忘了是怎么操作的了，到时候再摸索一遍，实在是太痛苦。

但是对于我一般出现这个，是因为在错误的环境下安装了这个包，特指base环境，记得切换到需要安装的虚拟环境哦！pip install --upgrade 包名--ignore-installed。

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project. 此类报错的解决办法 报错的原因：这是一个distutils安装的项目，因此我们无法准确确定属于该文件的文件，这只会导致部分卸载。 一般是你安装的版本是新版的，需要uninstall旧版的，但是由于直接使用pip uninstall+ 库名 不能对其完全卸载，所以最粗暴的方法就是把旧版的文件直接删掉。解决方法：进入anaconda3→Lib→site-packag
