Cryptography Assertionerror: Sorry, But This Version Only Supports 100 Named Groups

I'm installing several python packages via pip install on travis, language: python python: - '2.7' install: - pip install -r requirements/env.txt Everything worked fine, but toda

Solution 1:

There is a bug with PyCParser - See https://github.com/pyca/cryptography/issues/3187

The work around is to use another version or to not use the binary distribution.

pip install git+https://github.com/eliben/pycparser@release_v2.14

or

pip install --no-binary pycparser
