据我所知,pip安装[extras_require here]一直工作。在添加该功能时,我找不到任何文档,但即使是在非常旧的机器上,我也从未遇到任何问题。pip install [测试]不能在python2.7.9下工作pip版本6.0.7
是pip绝对是这里的问题。我可以添加'pip install --upgrade pip',但是我没有对当前存在问题的repo的合并权限。
从setup.py
extras_require={
'test': ['flake8', 'pytest>=2.9.0'],
},
在蟒蛇2.7.9
$ python --version
Python 2.7.9
$ pip --version
pip 6.0.7 from /home/travis/virtualenv/python2.7.9/lib/python2.7/site-packages (python 2.7)
$ pip install .[test]
Collecting .[test]
Could not find any downloads that satisfy the requirement .[test]
No distributions at all found for .[test]
The command "pip install .[test]" failed and exited with 1 during .
从3.5.2:
$ python --version
Python 3.5.2
$ pip --version
pip 9.0.1 from /home/travis/virtualenv/python3.5.2/lib/python3.5/site-packages (python 3.5)

它看起来像在1.1版本的pip版本中已经被支持。见[这里](http://stackoverflow.com/questions/4796936/does-pip-handle-extras-requires-from-setuptools-distribute-based-sources)。 – Brian
