title: Can't set environment variables at my bashrc file (Permission Denied)
body: <p>I was trying to set some environment variables requested by python on my macOS 10.14.6, however when I look up to my bashrc file at <code>/etc/</code> I can't do anything (<code>nano ~/.bashrc</code>) since I only have permission to read the file. A thing that makes me wondering is that this file is named as bashrc instead of .bashrc, same thing to my bash_profile.</p>
  <p>Hope you can help me, I've been searching answers for a long time, however didn't find one that works for me.</p>
