[Bug] Failed building wheel for cryptography

Executed Command pip install cryptography==1.4

Error occured build/temp.linux-x86_64-2.7/_openssl.c:429:30: fatal error: openssl/opensslv.h: No such file or directory

Proposed Solution Try to run this command from the system terminal. Make sure that you use the correct version of 'pip' installed for your Python interpreter located at '/usr/bin/python2.7'.
