Question

当我保存时,PyCharm正在把这个异常弄得一团糟.

并给我这个错误信息.

我不认为这是.idea文件的权限或类似的问题,但我真的不确定.

我在堆栈跟踪中得到了一些其他错误和警告,但这是在我尝试保存项目时再次发生的错误和警告.

当我用这样的sudo运行PyCharm CE时,这个问题仍然存在 sudo -u [username] /Applications/PyCharm\ CE.app/Contents/MacOS/pycharm

有人有任何想法吗？

由于您使用的是社区版，我的答案几乎肯定不适用于您，但它可能会帮助其他遇到同样错误的人。

就我而言，我用来在远程服务器和本地设置之间进行同步的 nfs 共享存在一些问题。远程服务器上的文件和目录权限都很好。重新安装后umount <my_nfs_dir>，PyCharm 能够保存设置并停止抱怨。
