Cannot deploy app | Protobuf Issues

Deployment
1

Summary

I’m having a hard time trying to get my app deployed as I keep getting hit with package conflict issues with protobuf.

If I use the latest version of protobuf, the app doesn’t work locally, giving this instruction’ Downgrade the protobuf package to 3.20.x or lower.’

If I downgrade protobuf to 3.20.0 the app works perfectly locally, but then fails deployment as it seems other packages require a more recent protobuf version?

Is there a magic protobuf version I need to use?

Expected behavior:

App gets deployed successfully

Actual behavior:

Deployment fails as ‘Error installing requirements.’

Debug info

ERROR: Cannot install -r /app/file_uploader/requirements.txt (line 18) and protobuf==3.20.0 because these package versions have conflicting dependencies.


The conflict is caused by:

    The user requested protobuf==3.20.0

    google-api-core 2.11.0 depends on protobuf!=3.20.0, !=3.20.1, !=4.21.0, !=4.21.1, !=4.21.2, !=4.21.3, !=4.21.4, !=4.21.5, <5.0.0dev and >=3.19.5


To fix this you could try to:

1. loosen the range of package versions you've specified

2. remove package versions to allow pip attempt to solve the dependency conflict

Hi @Thomas_Ellyatt, welcome to the forum!

Changing these lines worked for me requirements.txt protobuf - Diff Checker with python 3.10.3

Here’s how I went about resolving this:

  1. Tried to install it in a new virtual environment and verified that I got the same error you did
  2. Looked for a compatible version of protobuf according to the error (first tried 3.19.4)
  3. Saw a new issue complaining about 3.19.4, saying some dependencies needed >= 3.19.5, so I tried 3.19.5
  4. Noticed some issues related to grpcio, so I tried unpinning those packages (leaving off the ==) in the requirements.txt, and pip installing to see if it found a compatible version
  5. Once it worked, I used pip freeze | grep grpcio to see what versions got installed, and updated the requirements.txt to reflect those.

Hope this works for you, and those steps are helpful for the future.
