installing issues

I had some issues having downloaded your flask-starter-master.zip and following your getting started procedure:

  • cmd "python manage.py migrate init" leads to error "Directory alembic already exists".

Maybe the git-hub source should come with directory /alembic and alembic.ini removed so that a new user will not run into this issue when following your instructions.

  • cmd "python manage.py migrate revision --autogenerate -m "message describing migration" leads to error "ImportError: No module named MySQLdb"

Seems that mysql-python is a requirement...? This should be added to the requirement.txt list.

  • Having installed mysql-python and rerunning cmd "python manage.py migrate revision --autogenerate -m "message describing migration" the next error was "sqlalchemy.exc.OperationalError: (OperationalError) (1049, "Unknown database 'machineqa'") None None". Seems that no database was created...
  • Having created the database manually in mysql and rerunning cmd "python manage.py migrate revision --autogenerate -m "message describing migration" the next error was OSError: [Errno 2] No such file or directory: 'alembic/versions'.
  • Having manually created the folder 'alembic/versions' things went fine until launching dev.py where the web browser showed the following the error " "GET /login?next=%2F HTTP/1.1" 500 -

not sure what file is missing here...

Hi, thanks for the feedback - looks like I skipped some necessary info - sorry for the issues. I've updated the readme to cover all the issues you ran into and have added the MySQL and PostgreSQL drivers to requirements (I think I decided to not add them since you could use either MySQL or PostgreSQL but didn't specify).

The last issue seems to be related to not being able to find the less compiler on your machine. Have you run the npm install -g less and npm install -g coffee-script commands? If you have, then could you let me know what OS you are using and I could try and reproduce?

spitzbubchen commented

Yes, that was the issue, less and coffee-script wasn't properly installed. Thank you!

I know this is old but python manage.py wizard is what we need apparently?
