title: Conda error: The environment is inconsistent, please check the package plan carefully
body: <p>I tried to update my Pandas package via Conda prompt, however, it altered me the 'environment inconsistency'</p>
  
  <p>I have tried 'conda install anaconda' from the advice: <a href="https://stackoverflow.com/questions/55527354/the-environment-is-inconsistent-please-check-the-package-plan-carefully">The environment is inconsistent, please check the package plan carefully</a></p>
  
  <p>But it does not fix the problem, it failed </p>
  
  <p>(base) C:\Users\leon>conda install anaconda</p>
