protoc installation
Overview
protoc is a tool to generate code based on proto files that generate code in multiple languages such as C++, Java, Python, Go, PHP, etc. while gRPC code generation depends on protocol-gen-go,protocol-gen-go-grpc plugin for gRPC code generation in Go language.1. one-click Installation (recommended)
You can install with goctl one click installation protocol,protocol-gen-go,protocol-gen-go-grpc related components, you can execute the following command：
$ goctl env check --install --verbose --force
For more information about goctl env instructions, refer to goctl env

2.2 Installation
Extract downloads and move them to $GOBIN directory, see $GOBIN directory：
$ go env GOPATH
GOBIN is $GOPATH/bin, if you $GOPATH do not $PATH you need to add it to $PATH.
3. Validation
Once installed, you can perform the following instructions to verify whether you have installed successfully：
$ goctl env check --verbose
[goctl-env]: preparing to check env
[goctl-env]: looking up "protoc"
[goctl-env]: "protoc" is installed
[goctl-env]: looking up "protoc-gen-go"
[goctl-env]: "protoc-gen-go" is installed
[goctl-env]: looking up "protoc-gen-go-grpc"
[goctl-env]: "protoc-gen-go-grpc" is installed
[goctl-env]: congratulations! your goctl environment is ready!
