Resolve pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (openssl)

# yum
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   pycurl: libcurl link-time ssl backend (nss) is different from compile-time ssl backend (openssl)

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.7.5 (default, Nov  6 2016, 00:28:07)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)]

If you cannot solve this problem yourself, please go to
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

Fix

pip uninstall pycurl
export PYCURL_SSL_LIBRARY=nss
pip install --compile --install-option="--with-nss" --no-cache-dir pycurl
