Modules inside firebase cloud functions with python: ModuleNotFoundError: No module named 'src'

python

I have a directory structure like this:

python-functions/
--src
---- | api/
-------- | __init__.py
-------- | main.py
---- | __init__.py
---- | main.py

I’m trying to define all my functions in src/main.py but have the implementations in its corresponding folder

# src/main.py
import src.api.main as api

@https_fn.on_request(timeout_sec=300)
def status(req: https_fn.Request) -> https_fn.Response:
    return api.status(req)
# src/api/main.py
def status(req: https_fn.Request):
    return https_fn.Response("Hello", status=200)

But when deploying I get this error:

# Importing like: import src
ModuleNotFoundError: No module named 'src'
127.0.0.1 - - [18/May/2023 00:09:43] "GET /\_\_/functions.yaml HTTP/1.1" 500 -
Error: Failed to parse build specification:

- FirebaseError Expect manifest yaml to specify a version number

or this one:

# importing like: from .api.main import main
ImportError: attempted relative import with no known parent package

127.0.0.1 - - [18/May/2023 00:28:19] "GET /__/functions.yaml HTTP/1.1" 500 -

Error: Failed to parse build specification:
- FirebaseError Expect manifest yaml to specify a version number

I’ve tried other ways of importing like but I still get the same errors.

It looks like there are issues with your project’s directory structure and how you’re trying to import modules. Here are some suggestions to resolve the problems:

Update sys.path: Add the root directory of your project to sys.path in your scripts. You can do this in your main.py files.

```
# src/main.py
import sys
sys.path.append(‘/path/to/your/python-functions’)
import src.api.main as api

@https_fn.on_request(timeout_sec=300)
def status(req: https_fn.Request) -> https_fn.Response:
return api.status(req)
```

python # src/api/main.py def status(req: https_fn.Request): return https_fn.Response("Hello", status=200)

Use Relative Imports: In your src/api/main.py, use relative imports instead of absolute imports.

```python
# src/api/main.py
from .. import https_fn

def status(req: https_fn.Request):
return https_fn.Response(“Hello”, status=200)
```

Ensure Correct Module Names: Make sure that the module names in your imports match the actual file names and folder structure. Ensure there are no typos.
Check Working Directory: Ensure that the working directory when running your script is set to the root of your project.

python cd /path/to/your/python-functions python src/main.py

Firebase Configuration: The Firebase error you are encountering might be a separate issue. Ensure that your Firebase configuration files are correctly set up and that your functions.yaml specifies a version number.

By addressing these points, you should be able to resolve the import issues and deploy your functions successfully.
