Pip running goes wrong

[悬崖勒马2011]

I use ubuntu 14.04, and when I run pip, it always show

AttributeError: 'module' object has no attribute 'SSL_ST_INIT'

I checked pip version, it shows

"python-pip is already the newest version."

I tried: "pip install --upgrade pyOpenSSL", it returns same problem.
When I run: sudo apt-get install python-openssl, it says: python-openssl is already the newest version.

How can I solve this?

Thanks!
