~/.config/pip/pip.conf

 

Mac OSX:

~/Library/Application Support/pip/pip.conf

~/.pip/pip.conf

/Library/Application Support/pip/pip.conf

 

Windows:

%HOME%\pip\pip.ini

C:\Documents and Settings\All Users\Application Data\PyPA\pip\pip.conf (Windows XP)

C:\ProgramData\PyPA\pip\pip.conf (Windows 7及以后)

 

pip配置的主要一些配置：

 

可以配置如下：

 

[global]

index-url = http://pypi.douban.com/simple #豆瓣源，可以换成其他的源

trusted-host = pypi.douban.com            #添加豆瓣源为可信主机，要不然可能报错

disable-pip-version-check = true         
#取消pip版本检查，排除每次都报最新的pip

timeout = 120
