python包搜索路径_查看包搜索路径sys.path的N个方法

import失败的时候&＃xff0c;常常要去看看模块所在的路径是否包含在了sys.path内。有很多方法可以查看sys.path。

常规方法

常规方法就是登陆python shell&＃xff0c;导入sys&＃xff0c;查看sys.path。

>>> from pprint import pprint

>>> import sys

>>> pprint(sys.path)

[&＃39;&＃39;,

&＃39;/usr/local/python3.8.6/lib/python38.zip&＃39;,

&＃39;/usr/local/python3.8.6/lib/python3.8&＃39;,

&＃39;/usr/local/python3.8.6/lib/python3.8/lib-dynload&＃39;,

&＃39;/home/xinlin/.local/lib/python3.8/site-packages&＃39;,

&＃39;/usr/local/python3.8.6/lib/python3.8/site-packages&＃39;]

python3 -c&＃xff0c;表示直接在命令行执行python语句。

$ python3 -c &＃39;print("\n".join((__import__("sys").path)))&＃39;

/usr/local/python3.8.6/lib/python38.zip

/usr/local/python3.8.6/lib/python3.8

/usr/local/python3.8.6/lib/python3.8/lib-dynload

/home/xinlin/.local/lib/python3.8/site-packages

/usr/local/python3.8.6/lib/python3.8/site-packages

python3 -m&＃xff0c;表示将模块执行&＃xff0c;有很多模块是可以直接执行的&＃xff0c;它们都含有可直接执行的代码&＃xff0c;或用于测试&＃xff0c;或提供某种功能。

$ python3 -m site

sys.path &＃61; [

&＃39;/home/xinlin/repos&＃39;,

&＃39;/usr/local/python3.8.6/lib/python38.zip&＃39;,

&＃39;/usr/local/python3.8.6/lib/python3.8&＃39;,

&＃39;/usr/local/python3.8.6/lib/python3.8/lib-dynload&＃39;,

&＃39;/home/xinlin/.local/lib/python3.8/site-packages&＃39;,

&＃39;/usr/local/python3.8.6/lib/python3.8/site-packages&＃39;,

]

USER_BASE: &＃39;/home/xinlin/.local&＃39; (exists)

USER_SITE: &＃39;/home/xinlin/.local/lib/python3.8/site-packages&＃39; (exists)

ENABLE_USER_SITE: True

python3 -m site&＃xff0c;算不算python3的一个彩蛋呢&＃xff01;。。。(我知道的python第一个彩蛋是python的禅)
