body: <p>How can I install python3-dev in Oracle Linux?</p>
  
  <p><code>yum install python3-dev</code> is not working.</p>
  
  <p>It gives a message:</p>
  
  <blockquote>
    <p>No package python3-dev available.</p>
  </blockquote>
  
  <p>I need python3-dev to convert a python script to Linux executable using Cython.</p>
  
  <p>I tried to search rpm files, that also did not work.</p>
