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:
- Update Installation Method: As of Go 1.17, using go get to install executables is deprecated. Use go install instead.
-
Set Environment Variables: Configure the GOPATH and PATH environment variables as follows:
-
~/.bashrc
export GOPATH=$HOME/go export PATH=$PATH:$GOPATH/bin
-
-
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
-
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.

Go Error Handling: Best Practices and PatternsMay 04, 2025 am 12:19 AMIn Go programming, ways to effectively manage errors include: 1) using error values instead of exceptions, 2) using error wrapping techniques, 3) defining custom error types, 4) reusing error values for performance, 5) using panic and recovery with caution, 6) ensuring that error messages are clear and consistent, 7) recording error handling strategies, 8) treating errors as first-class citizens, 9) using error channels to handle asynchronous errors. These practices and patterns help write more robust, maintainable and efficient code.
How do you implement concurrency in Go?May 04, 2025 am 12:13 AMImplementing concurrency in Go can be achieved by using goroutines and channels. 1) Use goroutines to perform tasks in parallel, such as enjoying music and observing friends at the same time in the example. 2) Securely transfer data between goroutines through channels, such as producer and consumer models. 3) Avoid excessive use of goroutines and deadlocks, and design the system reasonably to optimize concurrent programs.

Centralized Error Handling Strategies in GoMay 03, 2025 am 12:17 AMCentralized error handling can improve the readability and maintainability of code in Go language. Its implementation methods and advantages include: 1. Separate error handling logic from business logic and simplify code. 2. Ensure the consistency of error handling by centrally handling. 3. Use defer and recover to capture and process panics to enhance program robustness.
