前提是只输入pycharm能正常打开PyCharm，但是用sudo pycharm会出现如下报错：

$ sudo pycharm

Failed to initialize graphics environment

java.awt.AWTError: Can't connect to X11 window server using 'localhost:12.0' as the value of the DISPLAY variable.

解决方法

cd ~
vim .bashrc

将xhost + local:all添加到 export的后面一行，PATH的前面一行
之后:wq保存

然后终端输入env |grep DISPLAY，将结果复制

$ env |grep DISPLAY
DISPLAY=localhost:12.0

然后寻找 pycharm.sh 文件

bgone@federo~
$ which pycharm
/usr/local/bin/pycharm
bgone@federo~
$ cd /usr/local/bin/
bgone@federo /usr/local/bin
$ ll |grep pycharm
lrwxrwxrwx 1 root root          46 Apr 14 12:19 pycharm -> /opt/pycharm-community-2021.1.2/bin/pycharm.sh
bgone@federo /usr/local/bin
$ cd /opt/pycharm-community-2021.1.2/bin
bgone@federo /opt/pycharm-community-2021.1.2/bin
$ vim pycharm.sh

将export DISPLAY=localhost:12.0添加到脚本开头，没有权限要先授权；保存关闭后，
打开一个终端输入pycharm,出现pycharm窗口后，再开一个终端，输入sudo pycharm,会再出现一个窗口，把两个都关掉，重启之后用sudo pycharm就能打开pycharm了
