Python pip install修改默认下载路径

1. 查看Python安装和依赖信息：cmd命令窗口python -m site

E:workspacepythonDjango>python -m site                                                                
sys.path = [                                                                                             
    'E:\workspace\python\Django',                                                                     
    'D:\Program Files\python\python37.zip',                                                           
    'D:\Program Files\python\DLLs',                                                                   
    'D:\Program Files\python\lib',                                                                    
    'D:\Program Files\python',                                                                         
    'C:\Users\Administrator\AppData\Roaming\Python\Python37\site-packages',                       
    'D:\Program Files\python\lib\site-packages',                                                     
    'D:\Program Files\python\lib\site-packages\you_get-0.4.1475-py3.7.egg',                         
]                                                                                                        
USER_base: 'C:\Users\Administrator\AppData\Roaming\Python' (exists)                                 
USER_SITE: 'C:\Users\Administrator\AppData\Roaming\Python\Python37\site-packages' (exists)        
ENABLE_USER_SITE: True

可以看到

• python安装目录
• USER_SITE：自定义Python依赖安装包的基础路径
• USER_base:自定义Python脚本

2. 查看依赖配置site.py的路径

   python -m site -help                                                          
   # site.py的路径
   D:Program Filespythonlibsite.py [--user-base] [--user-site]     
   

3. 修改site.py

# USER_SITE = None
# USER_base = None
USER_SITE = "D:\Program Files\python\Lib\site-packages"
USER_base = "D:\Program Files\python\scripts"

注意尽量写到python目录
