Database was not Created

[Dillon868]

After running python3 db_create.py the following error occurred: File "C:\Users\Admin\Desktop\mutate_cpp-master\db_create.py", line 3, in
from migrate.versioning import api
ModuleNotFoundError: No module named 'migrate'

Any advice would be appreciated.

Did you follow the installation instructions (https://github.com/nlohmann/mutate_cpp#installation)? What OS are you using?

[Dillon868]

I did follow the instructions. I’m using Windows 10

Before calling

python3 db_create.py

did you source the environment? That said, can you make sure you actually call venv/bin/python3?

Same error on Ubuntu 22.04.

I ran:

pip install virtualenv
virtualenv -p python3 venv
venv/bin/python3 db_create.py

Same error as above:

ModuleNotFoundError: No module named 'migrate'

As you mentioned, did I install the requirements? I had not, so next I ran:

venv/bin/pip install -r requirements.txt
venv/bin/python3 db_create.py

New error, now SQL Alchemy is missing (although I see it being installed by pip):

ModuleNotFoundError: No module named 'sqlalchemy.databases'

Here is the output of pip3 to make sure everything is installed for python3:

[nlohmann]

Maybe there are incompatible packages... Could you try replacing all >= entries in the requirements.txt with == and set up the virtual environment again?

[AlexisWilke]

That worked! :-)

I can now see the site. That may have other issues, but I suspect that it will work as expected.

Thank you.
