如果没有设置PYTHONUSERBASE，默认会安装在~/.local下
如果不希望安装在.local目录下，可以通过配置环境变量PYTHONUSERBASE指定对应的路径，比如/usr/local
当然也可以直接修改site.py的_getuserbase方法，通过设置USER_SITE和USER_BASE来指定
即调整USER SITE有2种方式：
1. 设置环境变量PYTHONUSERBASE
2. 设置site.py的对象变量USER_SITE和USER_BASE
$ export PYTHONUSERBASE=/usr/local
$ source .bashrc
$ python3 -m site -help
/usr/lib/python3.8/site.py [--user-base] [--user-site]
Without arguments print some useful information
With arguments print the value of USER_BASE and/or USER_SITE separated
by ':'.
Exit codes with --user-base or --user-site:
0 - user site directory is enabled
1 - user site directory is disabled by user
2 - uses site directory is disabled by super user
or for security reasons
>2 - unknown error
$ python3 -m site
