Hello,
I'm trying to setup the Neo4J-Flask course but, after some tries I still receive the same error when launch Flask run command:
"Error: While importing 'api', an ImportError was raised."
below the full cmd log.
New to Flask configuration (Windows).
Thanks for hints.
Best regards
(sandbox) C:\VirtualEnv\Neo4J\_Flask\>flask run
- Serving Flask app 'api' (lazy loading)
- Environment: development
- Debug mode: on
Usage: flask run [OPTIONS]
Try 'flask run --help' for help.
Error: While importing 'api', an ImportError was raised.

Hi there,
so, after nearly throwing in the towel, I found a solution for me: I had the wrong Python-Version (3.10) installed. Uninstalled Version 3.10 and **installing Version 3.9 works** now for me. Maybe the course designer could mark that with some color, that the Python version is crucial!
Hopefully I can do the course without any further obstacles now 😉

Hello all, is there a way to do this in Windows with python 3.10? I am getting the same error as above...

BTW as an FYI for Window cmd some of the code in the project setup is different:
1. sandbox\Scripts\activate instead of source sandbox/bin/activate
2. copy .env.example .env instead of cp .env.example .env

Hi,
I didn't find a solution. In order to make it work, the project needs to be rewritten with python 3.10 I think.

'Flask run' command only can be run under python-3.9.

Hi,
As an alternative you can use conda instead of venv (so frustating)
conda create -n pthon-neo4j python=3.9
(Mac Path) --\> /Users/\/opt/anaconda3/envs/pthon-neo4j/bin/pip install -r requirements.tx
And then
flask run
That worked for me!

Since it hasn't been stated yet, the course has been updated for python version 3.10. This issue should be resolved.
