I'm using the very latest Ubuntu 21.04 for aarch64. In order to experiment with gRPC, I installed grpc stuff:
python3 -m pip install grpc
python3 -m pip install grpcio-tools
I also tried:
pip3 install grpc
pip3 install grpcio-tools
These appeared to be successful however when I tried to generate my gRPC Python code from the .proto file, I was told by the system that grpcio-tools is not installed.
How to fix this? Is Ubuntu for aarch64 just broken?
For me the problem was that I used python instead of python3 when executed the generation:
python3 -m grpc_tools.protoc --help
I don't have access to an ARM64 instance and so can't repro this.
According to Running gRPC and Protobuf on ARM64 (on Linux), it should be supported (with Python)
Please include in your question more details.
For me on Ubuntu 20.04 on an AMD64:
python -m grpc_tools.protoc --help
/usr/bin/python: No module named grpc_tools
python -m venv venv
source venv/bin/activate
python3 -m pip install grpcio grpcio-tools

And, I can run e.g. the hello-world Python sample
It worked for me after closing both VSCode and Terminal, and starting them again.
