Answer 1

I suppose you need to install libffi-dev and libssl-dev lib to fix this problem. For Ubuntu user, run this command:

apt-get install libffi-dev libssl-dev

For Centos user, try this:

yum install openssl-devel

Also you can try to install these dependencies, and then retry.

apt-get install python-openssl
apt-get install python-gmpy
apt-get install python-gmpy2
