Flask app running into issue when running "fly launch"

Questions / Help Build debugging

I’m trying to deploy this app, but running into an issue. I’m able to run it locally without a problem. I’m using Windows 10.

The repo is here: gutoarraes/bot: chatbot (github.com)

Upon doing fly deploy I receive the following:

Upon running pip install python-dotenv it says Requirement already satisfied: python-dotenv in j:\vscode projects\chatbot\bot\.venv\lib\site-packages (1.0.1).

Hi there,

python-dotenv is not in your repo’s requirements.txt, so it’s not being installed in the image thus resulting in the error you see.

It works locally because you likely did pip install python-dotenv at some point, but didn’t add it to requirements.txt or run pip freeze.

Regards,
