Commands related to starting from a file

好像pip3 中并不在乎文件列表和位置
因为 这些文件不能独立执行,他们要被 python解释.
所以python好像将文件的概念给弱化了.

INSTALL OPTIONS
       pip install installs packages from:

          • PyPI (a.k.a. The Cheeseshop) and other indexes, using requirements specifiers.

          • VCS project urls.

          • Local project directories.

          • Local or remote source archives

          • Local wheel directories (python-pip-whl installs its wheels in /usr/share/ python-wheels and they can be locally installed by pip using --find-links)
