pip允许将所有的默认选项保存为一个ini格式的配置文件pip.conf

---------以下来源于官方文档------------------

Per-user:

• On Unix the default configuration file is: 

  $HOME/.config/pip/pip.conf

   which respects the 

  XDG_CONFIG_HOME

   environment variable.
• On macOS the configuration file is 

  $HOME/Library/Application Support/pip/pip.conf

   if directory 

  $HOME/Library/Application Support/pip

   exists else 

  $HOME/.config/pip/pip.conf

  .
• On Windows the configuration file is 

  %APPDATA%\pip\pip.ini

  .

There is also a legacy per-user configuration file which is also respected. To find its location:

• On Unix and macOS the configuration file is: 

  $HOME/.pip/pip.conf

• On Windows the configuration file is: 

  %HOME%\pip\pip.ini

You can set a custom path location for this config file using the environment variable 

PIP_CONFIG_FILE

.

Inside a virtualenv:

• On Unix and macOS the file is 

  $VIRTUAL_ENV/pip.conf

• On Windows the file is: 

  %VIRTUAL_ENV%\pip.ini

Global:

• On Unix the file may be located in 

  /etc/pip.conf

  . Alternatively it may be in a “pip” subdirectory of any of the paths set in the environment variable 

  XDG_CONFIG_DIRS

   (if it exists), for example 

  /etc/xdg/pip/pip.conf

  .
• On macOS the file is: 

  /Library/Application Support/pip/pip.conf

• On Windows XP the file is: 

  C:\Documents and Settings\All Users\Application Data\pip\pip.ini

• On Windows 7 and later the file is hidden, but writeable at 

  C:\ProgramData\pip\pip.ini

• Global configuration is not supported on Windows Vista.
