和以前一样,pip只是尝试requirements.txt从期望它是包名称的远程存储中获取。

pip help install

用法:

pip install [options] <requirement specifier> [package-index-options]...
pip install [options] -r <requirements file> [package-index-options]...

...

pip also supports installing from "requirements files", which 
provide an easy way to specify a whole environment to be installed.
