Error protoc-gen-go-grpc: program not found or is not executable occurs in Go you try to “generate Go gRPC code using the protoc tool, but the required plugin protoc-gen-go-grpc is not installed or not in the system’s PATH.”
Diagram of error and its solution
How to fix the error?
To fix the protoc-gen-go-grpc: program not found or is not executable error in Go, install the protoc-gen-go-grpc plugin using this command: go install google.golang.org/protobuf/cmd/protoc-gen-go@latest. This command will download and install the protoc-gen-go-grpc plugin into your GOBIN or GOPATH/bin directory.
Starting in Go 1.17, installing executables with “go get” has been deprecated. That’s why I used “go install.”
After installing the plugin, follow these steps:
- Ensure that your GOBIN or GOPATH/bin directory is added to your system’s PATH environment variable. This allows the protoc compiler to find and use the protoc-gen-go-grpc plugin.
- Add the following line to your ~/.bashrc, ~/.bash_profile, or ~/.zshrc file (depending on your shell):
export PATH=$PATH:$(go env GOPATH)/bin - After adding this line, restart your terminal or run source ~/.bashrc, source ~/.bash_profile, or source ~/.zshrc to apply the changes.
Now the protoc compiler should be able to find and use the protoc-gen-go-grpc plugin when generating the gRPC code for Go. This is a one-stop solution, as I fixed the error myself, and it will work for you as well.
If you are using Linux, you can download the package using this command:
sudo apt install golang-goprotobuf-devThat’s it.
