Couldn't build proto file into descriptor pool

[wadeira]

I'm getting this error when i try to run my program.

from steam import SteamClient
from csgo import CSGOClient

client = SteamClient()
cs = CSGOClient(client)


client.cli_login()
client.run_forever()


@cs.on('ready')
def gc_ready():
	print("Game coordinator is now ready!")


@cs.on('notready')
def gc_notready():
	print("Lost connection to Game Coordinator!")

What OS? Can you also provide the output of pip freeze ?

Right, this is an issue with protobuf binary wheels. The work around it to install the pure python implementation or fix proto files, so they don't have namespace collisions.

pip uninstall protobuf
pip install --no-binary=protobuf protobuf

Ref: protocolbuffers/protobuf#2739

[wadeira]

It works now, thanks for the help!

[rossengeorgiev]

I've implemented a fix in the way protobufs are compiled. Using the binary protobuf package should work now.

@rossengeorgiev I have another question, how to write pip install --no-binary=protobuf protobuf this in requirements.txt file?

[rossengeorgiev]

Hi @caimaoy, that is not possible, but you shouldn't need to.

I recently ran into this issue while deploying gcp cloud functions in Python. Here is my requirements.txt

jsonschema
protobuf
google-cloud-firestore
google-cloud-logging
apache_beam[gcp]
dependency/dist/schema-registry-client-0.1.1 #this is the private dependency I want to be installed using pip while deployment.

can you please help in solving this issue?

@onkarpathak833 See #8 (comment) that is all I know.
