Pip error on install (python 2.6)

[kjav]

Hi,

I was trying to install the latest version of cryptography on a build machine that doesn't currently have cryptography installed, and received an error that I can't understand. I installed the libffi-devel package from yum before running pip install cryptography.

What does this error mean, and how can I fix it?

Running setup.py develop for cryptography

Thanks very much

Could you show us the output of a pip freeze? This looks like a problem with cffi, but I'm unsure why.

Yep! Thanks for the reply.

[reaperhulk]

Definitely the right version of cffi. Would you mind upgrading your pycparser to 2.14 (the latest) to see if that resolves the issue?

Successfully installed cryptography

That fixed the issue. Thank you so much!
