   @lhyundeadsoul I added the two lines and ran the command `docker-compose up`. Still I'm getting the  error.
   Do I need to again run some installation steps ?
   
   In fact there's a new error also.
   `Traceback (most recent call last):
     File "/usr/local/lib/python3.6/site-packages/flask/_compat.py", line 35, in reraise
       raise value
     File "/usr/local/lib/python3.6/site-packages/flask/cli.py", line 95, in find_best_app
       module=module.__name__
   flask.cli.NoAppException: Failed to find Flask application or factory in module "app". Use "FLASK_APP=app:name to specify one.`
   
   My docker-entrypoint.sh file looks something like this
   ```bash
   #!/bin/bash
   set -ex
   
   if [ "$#" -ne 0 ]; then
       exec "$@"
   elif [ "$SUPERSET_ENV" = "development" ]; then
       superset worker &
       # needed by superset runserver
       (cd superset/assets/ && yarn && yarn run sync-backend)
       (cd superset/assets/ && yarn run dev) &
       export FLASK_APP=superset
       export FLASK_ENV=development
       flask run -p 8088 --with-threads --reload --debugger --host=0.0.0.0
   elif [ "$SUPERSET_ENV" = "production" ]; then
       superset worker &
       superset runserver -a 0.0.0.0 -w $((2 * $(getconf _NPROCESSORS_ONLN) + 1))
   else
       superset --help
   fi
   ```
