I'd guess you have an old version of pip that doesn't understand the
environment marker on the very last line of the file. I would either:

- Upgrade pip

- Edit the requirements file and remove the last line if you have
Python 2.7 or remove everything from and including the ; onwards if
you have Python 2.6. Then, re-run pip install -r requirements_py2.txt.
