   My guess is that probably you installed airflow in `--editable` mode from sources (pip install -e ".")  and this caused 'provider' packages to be installed as well as providers available from sources (or you have airflow sources in the path). That confuses providers manager when combined with PYTHONPATH pointing to airflow sources (adn might behave differently depending on the working directory you are in). .
    
   There are several ways of solving the problem: 
   
   1) First of all this is bad idea if you want to run in production. I recommend to install airflow from package rather than from sources if possible. 
   2) If you sill decide to use --editable mode, you can uninstall all providers (after removing all provider packages (`pip freeze | grep 'apache-airlfow-providers'  | xargs  pip uninstall -y` should do that ). That should fix the problem.
   
   3) When you install Airflow 2.0.0 you can set `INSTALL_PROVIDERS_FROM_SOURCES` to `true` to avoid installing provider packages in the first place
   
   4) In Airflow 2.0.1 this will be fixed - #13439 , the providers will be automatically removed if you install airflow in editable mode. 
   
   I am closing this now, please let me know if my diagnosis if correct and if you managed to solve the problem. 
   
   If this is not the case, You might also have a problem that airflow is installed in a different namespace - please let me know more details of your installaton - how you installed airflow, which extras, whether you installed providers, do you have backport providers  installed etc.
