Python 为什么可以'；t root用户使用pip3安装的模块

我已经将我的操作系统更新为Fedora27，在以root运行Python时遇到了一个问题。我无法导入与pip3一起安装的模块，如PSUTIL

我已经通过pip3安装了psutil

[user@localhost ~]$ sudo pip3 install psutil
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.
Requirement already satisfied: psutil in /usr/local/lib64/python3.6/site-packages

我可以由普通用户导入psutil

[user@localhost ~]$ python3

>>> import sys
>>> print(sys.path)
['', '/usr/lib64/python36.zip', '/usr/lib64/python3.6', '/usr/lib64/python3.6/lib-dynload', '/usr/local/lib64/python3.6/site-packages', '/usr/local/lib/python3.6/site-packages', '/usr/lib64/python3.6/site-packages', '/usr/lib/python3.6/site-packages', '/usr/lib/python3.6/site-packages/pykakasi-0.24-py3.6.egg']
>>> import psutil
>>> 

但在运行root时无法导入psutil

[user@localhost ~]$ sudo python3

似乎在运行普通用户时，

'/usr/local/lib64/python3.6/site-packages'

和

'/usr/local/lib/python3.6/site-packages'

会添加到

sys.path

，但在使用root运行时，如何将它们添加到python3

尝试使用python安装的完整路径（即，以普通用户的身份运行

哪个python

，然后在sudo命令中使用该路径的返回值）可能重复python的详细功能
