 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

python2.6 is not supported anymore, try to change you SYS PATH to point for new python and pip

check this : Python ENV

alternatively you can use the following:

/path/to/pip3 install ....
/path/to/python3 <NAME_OF_THE_SCRIPT>

you need to set your PATH something like `export PATH="$PATH:/usr/local/bin/python"` that is depend where your python3 is installed you may found it out using `which python3` – LinPy May 15 '19 at 07:04
I update my answer for a workaround if you want to keep python2.6 the default for your system – LinPy May 15 '19 at 07:26

Change your Default python version using this link Change default python version

you have installed pyopenssl for python2 environment. so first uninstall it.

check version: python3.6 -V, pip3 -V etc While installing pyopenssl or any software use pip3.

use sudo pip3 install pyopenssl or pip3 install pyopenssl, It will work.

This is because of some dependency problem. don't uninstall python2 otherwise you need to reinstall the centOS again. if you did then the dependancy problem will not go anyway. https://linuxize.com/post/how-to-install-python-3-on-centos-7/ – griez007 May 15 '19 at 07:37
