【中文标题】使用 Snap 重新安装后，启动时出现 PyCharm 错误“插件需要缺少‘Python’的类加载器”【英文标题】：PyCharm Error on Startup "plugin requires missing class loader for 'Python' " after reinstalling using Snap 【发布时间】：2021-08-22 11:19:15 【问题描述】：

从包含太多文件的文件夹打开创建项目后，PyCharm 2021.1.2 停止工作。所以我尝试使用

重新安装Pycharm

snap remove pycharm-professional --purge
rm -rf ~/snap/pycharm-professional/
rm -rf ~/.config/JetBrains
rm -rf ~/pycharm2021.1
snap install pycharm-professional --purge

当我从终端运行pycharm-professional 时，我在标准输出上收到很多错误，并且只有启动画面加载并停留。大多数错误说

“插件需要缺少'Python'的类加载器”
