Python Flask: Unable to Initialize SQLite Database
Pure educated guesswork here. But in the code you've shown you have the following:
@app.cli.command('initdb')def initdb_command(): """Initializes the database.""" init_db() print('Initialized the database.')I think that should be
@app.cli.command()def initdb(): ...Notice that there is no argument to the decorator and that the function was renamed to match the command you are invoking in the command line.
A cursory glance at the Flask and click docs does not show that you can pass a string to the decorator and invoke it as labeled.
I received the same error as I worked through the tutorial. I found that I had opened a new terminal window to work in why the server ran in another. I fixed the issue by running the export command again:
export FLASK_APP=flaskrThen:
flask initdb
Try this:
python -m flask initdb
Another thing to check, if you're going through the tutorial: is your __init__.py file in the correct location? It should be in the second level flaskr directory, not in the top-level directory.
