How to Fix the 'protoc-gen-go: program not found or is not executable' Error in gRPC Code Generation?

Generating gRPC Code: Resolving "protoc-gen-go: program not found or is not executable" Error

In attempting to build a gRPC application with Go, users may encounter difficulties when generating code using the "protoc" command. This error message, "protoc-gen-go: program not found or is not executable," indicates that the necessary tools are missing or not configured correctly.

Resolution for Go 1.17

Recent versions of Go have deprecated the use of "go get" for installing executables. Instead, use "go install" as recommended in the official documentation.

1. Update .bashrc:

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

   Copy after login

2. Install Tools:

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

   Copy after login

3. Generate Code:

   protoc --go-grpc_out=. *.proto

   Copy after login

Additional Notes:

• Ensure that the "go" command points to the correct Go installation.
• If the error persists, try setting the path to the "protoc-gen-go" executable explicitly.
• Consult the Go documentation for additional information on managing packages and tools: https://go.dev/doc/go-get-install-deprecation
