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

Resolving "protoc-gen-go: program not found or is not executable" Error in Go gRPC Projects

When attempting to generate code for a gRPC application in Go, users may encounter the "protoc-gen-go: program not found or is not executable" error. This issue arises because the protoc-gen-go plugin, a crucial component for code generation, is either absent or inaccessible.

Solution:

For Go versions 1.17 and above, the following steps should resolve the issue:

1. Update Installation Method: As of Go 1.17, using go get to install executables is deprecated. Use go install instead.

2. Set Environment Variables: Configure the GOPATH and PATH environment variables as follows:

   • ~/.bashrc

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

3. Install Plugins: Install the protoc-gen-go and protoc-gen-go-grpc plugins using:

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

4. Generate Code: Once the plugins are installed, use the following command to generate the code:

   protoc --go-grpc_out=. *.proto

By following these steps, you should be able to successfully generate code for your gRPC application in Go. Ensure that your environment variables are set correctly and that the necessary plugins are installed.
