1）安裝go 1.76

    a.環境變數設定很重要：

export GOROOT=/usr/local/go

export GOBIN=$GOROOT/bin

export GOARCH=amd64

export GOOS=darwin

export GOPATH=../GO

export PATH=/usr/bin:/usr/sbin:/bin:/sbin:/usr/X11R6/bin:/usr/local/go/bin:/usr/local/bin

  b.{gopath}  目錄結構

    bin

    pkg

    src

  c.讓當前mac使用者可以 管理/usr/local/go 目錄很重要，命令為：

sudo -i

Password:

chown -R ｛user｝ /usr/local/go

d.go 外掛安裝

• gocode: go get -u -v github.com/nsf/gocode
• godef: go get -u -v github.com/rogpeppe/godef
• golint: go get -u -v github.com/golang/lint/golint
• go-outline: go get -u -v github.com/lukehoban/go-outline
• goreturns: go get -u -v sourcegraph.com/sqs/goreturns
• gorename: go get -u -v golang.org/x/tools/cmd/gorename
• gopkgs: go get -u -v github.com/tpng/gopkgs
• go-symbols: go get -u -v github.com/newhook/go-symbols
• guru: go get -u -v golang.org/x/tools/cmd/guru

部分元件安裝下載不了，需要翻牆執行

除錯外掛安裝

安裝 homebrew https://brew.sh/

$ brew install go-delve/delve/delve

$go get -v -u github.com/derekparker/delve/cmd/dlv 再執行一遍

2）安裝vscode 1.151

    vscode環境變數user settings

3)下載go ethereum 1.6.7版本，原始碼拷貝程式碼到{gopath}/src/github.com/ethereum/go-ethereum 目錄下

4）ok
