golang環(huán)境安裝

brew install golang
保險起見可以先brew update

IDE安裝

可以直接使用sublime、webstrom、eclipse等,在這里我使用的是VSCode

• sublime: 沒辦法跑測試
• eclipse: 翻墻下載go插件好坑~~

Delve調(diào)試環(huán)境安裝

brew install go-delve/delve/delve
檢查是否安裝成功dlv version，提示不存在該命令

錯誤提示

解決辦法

cd $HOME/Library/Caches/Homebrew
tar xf delve-*.gz
go into directory ( mine is delve-1.0.0-rc.1 )
sh scripts/gencert.sh

it will asks for password, and you're done.
After that just re run brew install go-delve/delve/delve

參考：https://github.com/go-delve/homebrew-delve/issues/19#issuecomment-330442033

設(shè)置好后重新安裝

命令行dlv version

Delve Debugger
Version: 1.0.0
Build: v1.0.0

IDE啟動

檢測最簡單的服務(wù)器代碼

func HelloServer1(w http.ResponseWriter, req *http.Request) {

    fmt.Fprint(w,"hello world")
}
func main() {
    http.HandleFunc("/test", HelloServer1)
    err := http.ListenAndServe(":23456", nil)
    if err != nil {
        log.Fatal("ListenAndServe: ", err.Error())
    }
}

報錯如下

compile: version "go1.9" does not match go tool version "go1.9.1"
參考：https://stackoverflow.com/questions/46693653/compile-version-go1-9-does-not-match-go-tool-version-go1-9-1

解決辦法 export GOROOT=/usr/local/opt/go/libexec, 簡單粗暴

調(diào)試

提示錯誤：debugserver or lldb-server not found: install XCode's command line tools or lldb-server
老版本解決辦法：xcode-select --install
新版本不再有這個工具，只能去開發(fā)者網(wǎng)站下載：https://developer.apple.com/download/more/
找到自己對應(yīng)系統(tǒng)和xcode版本編號的下載即可

SUCCESS!
