The fix would be upgrading pip, which is not feasible unless we have newer packages and we're not using them... IIRC we use pip 1.5.6, release on May 17, 2014. The next version which fixes this problem is 6.0, released on Dec 22, 2014. There are many GitHub issues in the gunicorn project mentioning this "bug": https://github.com/benoitc/gunicorn/issues/860 https://github.com/benoitc/gunicorn/issues/810 https://github.com/benoitc/gunicorn/issues/1017 https://github.com/benoitc/gunicorn/issues/982 https://github.com/benoitc/gunicorn/issues/974 https://github.com/benoitc/gunicorn/issues/952 https://github.com/benoitc/gunicorn/issues/871 https://github.com/benoitc/gunicorn/issues/868 https://github.com/benoitc/gunicorn/issues/819 https://github.com/benoitc/gunicorn/issues/788 Issue on pip: https://github.com/pypa/pip/issues/1873 --- Additional comment from Michal Fojtik on 2015-08-17 07:35:12 EDT --- wewang, since this is pending a fix in upstream pip being available in RHEL package of 'pip', I'm moving this bug to SCL team to deal with it. There is nothing we can do about this right now. Please feel free to re-open this after the SCL team bump the version and you will still see this error.
