系统突然报错：fatal error: can’t write PCH file: 设备上没有空间,然后df -h查看原因：
root@ubuntu18-Slave-server:~# df -ih

如上所示:snap占用/dev/loop0-/dev/loop7占用100% ！
这时，我们只要清理掉一下就可以了.
sudo apt autoremove --purge snapd
Reading package lists... Done
Building dependency tree

The following packages will be REMOVED:

然后在查看，可以看见已经清理完毕：
