Note that '/home/wuxi/.local/share' is not in the search path
set by the XDG_DATA_HOME and XDG_DATA_DIRS
environment variables, so applications may not
be able to find it until you set them. The
directories currently searched are:

- /root/.local/share
- /usr/local/share/
- /usr/share/

• 默认值

$XDG_DATA_HOME      $HOME/.local/share
$XDG_DATA_DIRS      /usr/local/share/:/usr/share/

$XDG_CONFIG_HOME  $HOME/.config
$XDG_CACHE_HOME     $HOME/.cache
$XDG_CONFIG_DIRS  /etc/xdg

对于安装之类并无影响。
