Steps to replicate

Use this requirements.txt

[uranusjr]

Because pip just ignores the invalid tag. It is still invalid.

@techalchemy note that git+https://github.com/Theano/Theano.git@15c90dd3#egg=Theano==0.8.git works with pip.

You can test it with pip install -r https://raw.githubusercontent.com/Lasagne/Lasagne/v0.1/requirements.txt
