ModuleNotFoundError: No module named 'aws_langchain'


In local, I run this command to install the classes
pip install .

In cloud, it could not find the module, and I can't run cmd like "pip install aws_langchain".

What shall I do?

Hey @philipkang,

Can you share the GitHub repo for your app? You’ll need to add a requirements.txt file if you haven’t already so that the correct packages will be installed for your app.

That’s what I figured out by adding the requirements.txt file. Now the error complaining about ```

I have set the credentials such as AWS_REGION =“us-east-1” in the Secret of Settings. Not sure why it is still complaining.
