我有一个很棒的rc.lua文件，awesome 3.5和lua 5.2。当我使用awesome -k时，我得到以下结果：
mohsen@debian:~$ awesome -k
✔ Configuration file syntax OK.
但是当我使用时：
mohsen@debian:~$ lua .config/awesome/rc.lua
lua: .config/awesome/rc.lua:2: module 'gears' not found:
no field package.preload['gears']
no file '/usr/local/share/lua/5.2/gears.lua'
