==> Warning: Quotes in command arguments can confuse scripts like configure.
  The following arguments may cause problems when executed:
      source /dev/null &> /dev/null && python3 -c "import os, json; print(json.dumps(dict(os.environ)))"
  Quotes aren't needed because spack doesn't use a shell.
  Consider removing them
