  <pre><code>/opt/bitnami/python/bin/.python2.7.bin: error while loading shared libraries:
  libreadline.so.5: cannot open shared object file: No such file or directory
  </code></pre>
  
  <p>I've attempted to use the recommendation on this link [Bitnami - /opt/bitnami/python/bin/.python2.7.bin: error while loading shared libraries: libreadline.so.5](<a href="https://stackoverflow.com/questions/12814973/bitnami-opt-bitnami-python-bin-python2-7-bin-error-while-loading-shared-lib">Bitnami - /opt/bitnami/python/bin/.python2.7.bin: error while loading shared libraries: libreadline.so.5</a> and no prevai), but it was not helpful.</p>
  
  <p>Why do I receive the error?</p>
