...and is there a question in there somewhere??? You posted a dump of some generic package-install stuff, and don't bother providing ANY usable details. Read the "Question Guidelines" in my posting signature. Things like version/distro of Linux, etc.,

Actually I have mention it in subject line sorry for miscommunication ..

ansible installation error in centos 7

while installing using pip I got that error I have tried to install cryptography but still not work ..

And the VERY FIRST HIT in Google for "how to install ansible on centos 7" is:
http://www.liquidweb.com/kb/how-to-i...tos-7-via-yum/

...complete instructions on how to install via yum. Why are you installing via pip/source? And did you actually read what you posted? It says you have TWO cryptography packages (0.8.2 and you're trying to install 1.4). Pick one.
