title: Failed to find package metadata for jsonschema
body: <p>I am fairly new to this. I installed <code>jsonschema</code> and <code>importlib_metadata</code> manually and copied it to the folder where I was doing <code>synthesis</code> using <code>make syn</code> i.e., <code>vlsi</code> folder in my case.</p>
  <p>It terminates with this error: <code>importlib_metadata.PackageNotFoundError: No package metadata was found for jsonschema</code></p>
  <pre><code>[usr@serv vlsi]$ make syn
  ./example-vlsi -e /home/usr/chipyard/vlsi/env.yml  -p example.yml  -p /home/usr/chipyard/vlsi/build/chipyard.TestHarness.RocketConfig-ChipTop/inputs.yml --obj_dir /home/usr/chipyard/vlsi/build/chipyard.TestHarness.RocketConfig-ChipTop build

  <p>I found some solutions to this here: <a href="http://biercoff.com/how-to-fix-package-not-found-error-importlib-metadata/" rel="nofollow noreferrer">http://biercoff.com/how-to-fix-package-not-found-error-importlib-metadata/</a> but where to find serverless.yml file and will making <code>slim</code> true to false affect other things?
  Any idea what could be causing this error?</p>
