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.
