   @dosu,
   
   I am having the same error after Superset upgrade.
   Upgraded Superset from 3.0.0 to 4.1.1: `sudo pip install apache-superset --upgrade` .
   
   `superset db upgrade` passed successfully.
   
   `superset db init` returns an error: 
   ```
   ERROR:flask_migrate:Error: Directory /usr/local/lib/python3.9/site-packages/superset/extensions/../migrations already exists and is not empty
   ```
   
   I tried:
   1. deleting the `migrations` folder and running `superset db init`  again. 
   In this case the error message is:
   ```
   
   Traceback (most recent call last):
     File "/usr/local/bin/superset", line 5, in <module>
       from superset.cli.main import superset
     File "/usr/local/lib/python3.9/site-packages/superset/cli/main.py", line 53, in <module>
       module = importlib.import_module(module_name)
     File "/usr/lib64/python3.9/importlib/__init__.py", line 127, in import_module
       return _bootstrap._gcd_import(name[level:], package, level)
     File "/usr/local/lib/python3.9/site-packages/superset/cli/viz_migrations.py", line 27, in <module>
       from superset.migrations.shared.migrate_viz.base import (
   ModuleNotFoundError: No module named 'superset.migrations'
   ```
   2. Deleting all contents in the `migrations` folder except for python scripts and running `superset db init`  again. The error message persists:
   ```
   ERROR:flask_migrate:Error: Directory /usr/local/lib/python3.9/site-packages/superset/extensions/../migrations already exists and is not empty
   ```
   
   I run it on Linux CentOS.
   
   How to pass `superset db init` and fix the errors ?
