"You can install with" instruction is a bit odd

You can install the dependencies with

for req in $(cat requirements.txt); do pip install $req; done

Is a bit strange, when

pip install -r requirements.txt

Will do

No, pip install -r requirements.txt won't work.

Take a look at #1950 for details.

Ok, closing this as a duplicate of #1950 .... it's a horrible thing to try and workaround, I'm going to bash pip a bit and see what happens ...
