1、登录账户或切换账户时出现以下警告 ，如图
-bash: warning: setlocale: LC_CTYPE: cannot change locale (en US.UTF-8):no such file or directoty
-bash: warning: setlocale: LC_COLLATE: cannot change locale (en US.UTF-8):no such file or directoty
-bash: warning: setlocale: LC_MESSAGES: cannot change locale (en US.UTF-8):no such file or directoty
-bash: warning: setlocale: LC_NUMERIC: cannot change locale (en US.UTF-8):no such file or directoty
-bash: warning: setlocale: LC_TIME: cannot change locale (en US.UTF-8):no such file or directoty
实际上并非中文英文的问题，也不是其他问题，解决方法：仔细看上面几条警告是不是都指向一个地方（en US.UTF-8）,我搞了很久，找了很多方法，都没用，后来仔细一看，TMD中间少了个底杆
这次事故告诉我，做事要仔细
