title: pip install does not install package, only dist-info folder
body: <p>My package is not installing completely with pip. Importing the module does not work and there is only the dist-info directory in site-packages. I haven't been able to solve the issue with other posts. I have the following package structure. </p>
  
  <pre><code>idbd_utils
  +-- ncbi_taxonomy_utils
  |   +-- __init__.py
  |   +-- ncbi_taxonomy_utils.py 
  |   +-- ncbi_taxonomy_all_names.dat
  |   +-- ncbi_taxonomy_canonical_taxa.dat
  |   +-- ncbi_taxonomy_children_nodes.dat
  |   +-- ncbi_taxonomy_max_taxid.dat
  |   +-- ncbi_taxonomy_merged.dat
  |   +-- ncbi_taxonomy_names.dat
  |   +-- ncbi_taxonomy_nodes_rank.dat
  |   +-- ncbi_taxonomy_nodes_rel.dat
  +-- LICENSE
  +-- README.md
  +-- MANIFEST.in
  +-- setup.py
  </code></pre>
  
  <p>This is my setup.py</p>
  
  <pre><code>import setuptools
  
  with open("README.md", "r") as fh:
      long_description = fh.read()
  
  setuptools.setup(
      name="idbd_utils",
      version="0.0.1",
      author="Me",
      author_email="none@nomail.com",
      description="My packages",
      long_description=long_description,
      long_description_content_type="text/markdown",

          "License :: None",
          "Operating System :: OS Independent",
      ],
  )
  </code></pre>
  
  <p>To build, I use this command in the my_pckgs directory
  <code>python3 setup.py sdist bdist_wheel</code></p>
  
  <p>I then install with <code>pip install .</code></p>
  
  <p>When all is done, only my-pckgs-0.0.1.dist-info is in site packages, but no functional package. This is especially frustrating because it worked just fine before I changed the name of the parent directory (i.e. my_pckgs, which is just a pseudonym here, along with all other file names). I tried starting from scratch in a new directory but still have the same issue.</p>
  
  <p>Output from <code>pip install . -vvv</code></p>
