title: Deprecated wheel error when installing package in Python
body: <p>I am using Python 3-6.10, package which is supported by <code>Pycld2</code>.
  But when I call <code>pip install pycld2</code> in command prompt or in Jupyter Notebook, the same message appears:</p>
  <pre><code>**ValueError: path '/home/rmyeid/code/pycld2/bindings/encodings.cc' cannot be absolute**
    ----------------------------------------
  ERROR: Failed building wheel for pycld2
  Running setup.py clean for pycld2
  Failed to build pycld2
  DEPRECATION: Could not build wheels for pycld2 which do not use PEP 517. 
  pip will fall back to legacy 'setup.py install' for these. pip 21.0 will remove support for this functionality. 
  **A possible replacement is to fix the wheel build issue reported above. 
  You can find discussion regarding this at https://github.com/pypa/pip/issues/8368.**

  <p>From what I understand, it seems that there is a problem with the wheel (I don't know how to solve that),
  a problem with ValueError encodings and command error exit status 1.
  I don't know whether they are all the same problem.
  I have followed the link <a href="https://github.com/pypa/pip/issues/8368" rel="nofollow noreferrer">https://github.com/pypa/pip/issues/8368</a> and still can't find the solution.</p>
