go-zero protoc & protoc-gen-go安裝

前言

protoc是一款用C++編寫的工具，其可以將proto文件翻譯為指定語言的代碼。在go-zero的微服務(wù)中，我們采用grpc進行服務(wù)間的通信，而grpc的編寫就需要用到protoc和翻譯成go語言rpc stub代碼的插件protoc-gen-go。

方式一：goctl一鍵安裝

$ goctl env check -i -f --verbose                                 
[goctl-env]: preparing to check env

[goctl-env]: looking up "protoc"
[goctl-env]: "protoc" is not found in PATH
[goctl-env]: preparing to install "protoc"
"protoc" installed from cache
[goctl-env]: "protoc" is already installed in "/Users/keson/go/bin/protoc"

[goctl-env]: looking up "protoc-gen-go"
[goctl-env]: "protoc-gen-go" is not found in PATH
[goctl-env]: preparing to install "protoc-gen-go"
"protoc-gen-go" installed from cache
[goctl-env]: "protoc-gen-go" is already installed in "/Users/keson/go/bin/protoc-gen-go"

[goctl-env]: looking up "protoc-gen-go-grpc"
[goctl-env]: "protoc-gen-go-grpc" is not found in PATH
[goctl-env]: preparing to install "protoc-gen-go-grpc"
"protoc-gen-go-grpc" installed from cache
[goctl-env]: "protoc-gen-go-grpc" is already installed in "/Users/keson/go/bin/protoc-gen-go-grpc"

[goctl-env]: congratulations! your goctl environment is ready!

方式二： 源文件安裝

protoc安裝

• 進入protobuf release 頁面，選擇適合自己操作系統(tǒng)的壓縮包文件
• 解壓?protoc-x.x.x-osx-x86_64.zip?并進入?protoc-x.x.x-osx-x86_64?

  $ cd protoc-x.x.x-osx-x86_64/bin

• 將啟動的protoc二進制文件移動到被添加到環(huán)境變量的任意path下，如$GOPATH/bin，這里不建議直接將其和系統(tǒng)的以下path放在一起。

  $ mv protoc $GOPATH/bin

 Tip
$GOPATH為你本機的實際文件夾地址

• 驗證安裝結(jié)果

  $ protoc --version

  libprotoc x.x.x

protoc-gen-go/protoc-gen-go-grpc 安裝

• 下載安裝protoc-gen-go

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