python flask_migrate run - Flask - ImportError: No module named migrate.versioning
I'm working through a flask tutorial and am trying to run a script that creates a database instead of doing it through the command line. It uses the SQLAlchemy-migrate package, but when I try to run the script, it gives an ImportError.
This is the terminal output:
Sean:app seanpatterson$ python ./db_create.py Traceback (most recent call last): File "./db_create.py", line 2, in <module> from migrate.versioning import api ImportError: No module named migrate.versioning
This is the db_create.py script:
#!flask/bin/python from migrate.versioning import api from config import SQLALCHEMY_DATABASE_URI from config import SQLALCHEMY_MIGRATE_REPO from app import db import os.path db.create_all() if not os.path.exists(SQLALCHEMY_MIGRATE_REPO): api.create(SQLALCHEMY_MIGRATE_REPO, 'database repository') api.version_control(SQLALCHEMY_DATABASE_URI, SQLALCHEMY_MIGRATE_REPO) else: api.version_control(SQLALCHEMY_DATABASE_URI, SQLALCHEMY_MIGRATE_REPO, api.version(SQLALCHEMY_MIGRATE_REPO))
This is the config file it references:
#!/usr/bin/env python import os basedir = os.path.abspath(os.path.dirname(__file__)) SQLALCHEMY_DATABASE_URI = 'sqlite:///' + os.path.join(basedir, 'app.db') SQLALCHEMY_MIGRATE_REPO = os.path.join(basedir, 'db_repository')
This application is being run with a virtual environment. This are the module that relates to it that I have installed in the environment:
Any help appreciated
flask/bin/pip install flask-sqlalchemy without defining the version worked fine for me.
I had the same problem - "No module named migrate.versioning", and everything is much easier than we are talking about, you need to perform the commands "run" file: db_create.py or file: db_migrate.py if you using PyCharm (not from the terminal). And you will have the expected output: "New migration saved as D:...there is my path...\microblog\db_repositort/versions/001_migration.py Current database version: 1"
