ModuleNotFoundError: No module named 'google.cloud.location'

Question

We have an application that uses firestore. It is running on Python 3.x on standard Google app engine. The application was running fine, till this morning when we tried to run the new version. The deployment of the new version is executed without any error. The requirement.txt is as follows -

firebase_admin==3.0.0
sendgrid==6.9.3
google-auth==1.35.0
google-auth-httplib2==0.1.0
jinja2==3.0.3
MarkupSafe==2.0.1
pytz==2021.3
Flask==2.0.2
twilio==6.46.0
httplib2==0.20.2
requests==2.24.0
requests_toolbelt==0.9.1
google-cloud-tasks==2.7.1
google-cloud-logging==1.15.1
googleapis-common-protos==1.54.0
protobuf==3.20.1

We get the following error.

  File "/layers/google.python.pip/pip/lib/python3.7/site-packages/google/cloud/firestore_v1/services/firestore/client.py", line 55, in <module>

from google.cloud.location import locations_pb2  # type: ignore
ModuleNotFoundError: No module named 'google.cloud.location'

Please help.

Updated (9-24-2022) with the complete error output.

Answer 1

When I ran into this issue, I fixed by uninstalling and reinstalling python on my machine, then recreating my venv. Running python 3.10 and 3.11.

Answer 2

I got this exact same error just now while trying to link a Python script to Firestore. I don't know if this is a "correct" solution but I got my code to run and save data to my Firestore database after this doing this.

In the error message, this line specifies the file where google.cloud.location is being imported:

  File "/layers/google.python.pip/pip/lib/python3.10/site-packages/google/cloud/firestore_v1/services/firestore/client.py", line 55, in <module>

If you open the client.py file and comment out the line 55 ("from google.cloud.location import locations_pb2 # type: ignore"), then run your code again, the next error message will show the other file where google.cloud.location is being imported. Repeat this process for all five files where this module is imported. (client.py, base.py, grpc.py, grpc_asyncio.py, async_client.py)

From searching through the code, I'm seeing that locations_pb2 (imported from google.cloud.location) is never used. I suspect that commenting this out entirely won't affect the functionality of firebase_admin.

It looks like Google made a mistake in setting requirements for one its Python packages.

If you create a new virtual environment, install with pip install -r you should be able to recreate the error you are seeing in production.

To fix it, I would do pip list on your local machine (in the environment that is still working) and add fixed versions of other installed google packages until it works.

You can test by creating a new Python virtual environment, installing with pip install -r and seeing if it works.

It is a tedious process unfortunately.
