title: How to install python3-devel on red hat 7
body: <p>I am trying to install something in my virtual environment, which uses anaconda python 3.6. I get <code>the gcc failed with exit status 1</code>, hinting on the absence of the right python3-devel package, as described in <a href="https://stackoverflow.com/questions/11094718/error-command-gcc-failed-with-exit-status-1-while-installing-eventlet">error: command &#39;gcc&#39; failed with exit status 1 while installing eventlet</a>.</p>
  
  <p>To fix the error, I tried to install the python3-devel package on my server running RHEL 7.3. 
  I did <code>yum install python3-devel</code>, but got a <code>'package not found'</code> error. Then I found <a href="https://serverfault.com/questions/710354/repository-for-python3-devel-on-centos-7">https://serverfault.com/questions/710354/repository-for-python3-devel-on-centos-7</a>, which hints to the python34-devel package in the EPEL repository. I installed it using yum, but upon trying to install something in my virtual environment, I still get <code>the gcc failed with exit status 1</code> error.</p>
  
  <p>Does someone know how I can fix this? All help would be much apprechiated.</p>
