Why Does 'protoc' Fail with 'protoc-gen-go: Program Not Found' and How Do I Fix It?

Unable to Generate Code with "Protoc" Due to "protoc-gen-go: Program Not Found" Error

Question:

I am facing the following error when generating code with "protoc":

"protoc-gen-go: program not found or is not executable
--go_out: protoc-gen-go: Plugin failed with status code 1."

Despite installing the necessary libraries, such as google.golang.org/grpc and github.com/golang/protobuf/protoc-gen-go, I cannot resolve this issue.

Resolution:

For Go versions 1.17 and above, the installation of executables using go get is deprecated. Instead, use go install:

1. Update Environment Variables:

Edit ~/.bashrc or ~/.zshrc and add the following lines:

export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

2. Install Protobuf and gRPC Plugins:

Install the Protobuf and gRPC plugins using the following commands:

go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

3. Generate Code:

You should now be able to generate code using protoc as follows:

protoc --go-grpc_out=. *.proto
