很多小白通過pip安裝python包之后，不知道包的位置等詳細信息，本文將著手于解決這些問題。

一、切換到指定的python環境

C:\Users\****1>conda info --envs
C:\Users\****1>activate pytorch3.7

C:\Users\****1>conda info --envs
# conda environments:
#
base                  *  D:\ProgramData\Anaconda3
pytorch3.7               D:\ProgramData\Anaconda3\envs\pytorch3.7

C:\Users\****1>activate pytorch3.7

二、列出當前環境下所安裝的所有包并對特定包查找

(pytorch3.7) C:\Users\****1>pip list
