title: Installing vendor program - libpython3.so: cannot open shared object file
body: <p>I'm getting an error at runtime when running a vendor program. I've been getting several dynamic lib errors, and have been walking through and solving each one. I am stuck on 'python3'</p>
  
  <p>I am running CentOS 7.6.</p>
  
  <p>The error I am getting is:</p>
  
  <p>error while loading shared libraries: libpython3.so: cannot open shared object file: No such file or directory</p>
  
  <p>Usually I expect to search for the package, install it, and then add any paths as necessary.</p>
  
  <ol>
  <li>I tried ldd, but the vendor file isn't a dynamic executable.</li>
  <li>LD_LIBARY_PATH is set to /user/local/lib:/opt/lib:/usr/lib:/lib</li>
  <li>If I run python3.6 -V, I get 'Python 3.6.7' which indicates python 3.* is installed.</li>
  <li>I search from / for: python3*so and there are no libraries on my disk</li>
  </ol>
  
  <p>Searches reveal specific python library versions, but not a generic python3, I'm missing something. How do I install and resolve the python3 library dependency?</p>
