  <p>I have updated my pip version. <br>
  I tried to reinstall xcode command line tools again. <code>xcode-select --install</code><br>
  I installed <code>xcode</code>. <br>
  Tried to update setup tools <code>pip3 install --upgrade setuptools</code>.<br>
  I tried all solutions of this question : <a href="https://stackoverflow.com/questions/61365790/error-could-not-build-wheels-for-scipy-which-use-pep-517-and-cannot-be-installe">this SO solution</a></p>
  <p>Nothing seems to work, and I'm exhausted. Mac updates are worst. This is happening after I updated my mac last night.</p>
  <p>I have also installed cython using <code>pip install cython</code>.</p>
