Question

我知道pypi上有一个软件包目录，我很好奇要知道将pip配置为在pypi上专门寻找软件包的文件在哪里。我试图了解它的基本知识，任何相关信息都将有所帮助。

pip allows you to set all command line option defaults in a standard ini style config file.

The names and locations of the configuration files vary slightly across platforms. You may have per-user, per-virtualenv or site-wide (shared amongst all users) configuration:

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 are also a legacy per-user configuration file which is also respected, these are located at:

    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

Site-wide:

    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
    Site-wide configuration is not supported on Windows Vista

If multiple configuration files are found by pip then they are combined in the following order:

    The site-wide file is read
    The per-user file is read
    The virtualenv-specific file is read

我对默认软件包索引有相同的疑问。我们当然可以在pip.ini文件中或使用--index-url选项在命令行中覆盖它，但这不能解释pypi.org默认配置的位置。

所以我去了源代码，事实证明它是硬编码的。我至少在两个活动的源文件中看到了它：

index.py
locators.py。

This commit，默认设置于2018年更改。它显示了许多其他对其进行了硬编码的测试和文档文件。

当我运行“ pip install something”时，pip从何处获取此东西？
