Installation fails with no such option: --allow-external

[dzieciou]

I have followed installation instructions from https://blocks.readthedocs.io/en/latest/setup.html but the installation fails with

pip install git+git:/mila-udem/blocks.git@stable -r https://raw.githubusercontent.com/mila-udem/blocks/stable/requirements.txt
Usage: pip [options]

ERROR: Invalid requirement: --allow-external theano
pip: error: no such option: --allow-external

I've run it on on Windows 10 for Python 3.7 and pip 19.1.1 (higher than the required 1.5)

What am I missing?

Same here.

Also install master will have following error:

Same issue happened with me.

1. Install fuel.
2. Just clone the git and change the requirement.txt to the include the same numpy version as installed by the fuel.
   The problem is resolved.
