mac 搭建 sublime3 + golang 环境

搭建流程

• 默认情况下 preference – package control 是找不到GoSiblime 插件的
• 需要去github手动下载然后安装
• 步骤
  • 确保go的环境变量存在 echo $GOROOT echo $GOPATH 查看
  • cd /Users/yourname/Library/Application Support/Sublime Text 3/Packages
  • git clone https://margo.sh/GoSublime
  • 重新打开sublime option+` 打开控制台 没有报错就安装成功
• 如果有error
  • 则 command+. command+x 代开margo.go 替换所有代码为以下代码

  	package margo
  	
  	import (
  		"margo.sh/golang"
  		"margo.sh/mg"
  		"time"
  	)

  	func Margo(m mg.Args) {
  		// See the documentation for `mg.Reducer`
  		// comments beginning with `gs:` denote features that replace old GoSublime settings
  	
  		// add our reducers (margo plugins) to the store
  		// they are run in the specified order
  		// and should ideally not block for more than a couple milliseconds

  			//
  			// It adds a new command `motd.sync` available via the UserCmd palette as `Sync MOTD`
  			//
  			// Interval can be set in order to enable automatic update fetching.
  			//
  			// When new updates are found, it displays the message in the status bar
  			// e.g. `★ margo.sh/cl/18.09.14 ★` a url where you see the upcoming changes before updating
  			//
  			// It sends the following data to the url https://api.margo.sh/motd.json:
  			// * current editor plugin name e.g. `?client=gosublime`
  			//   this tells us which editor plugin's changelog to check
  			// * current editor plugin version e.g. `?tag=r18.09.14-1`
  			//   this allows us to determine if there any updates
  			// * whether or not this is the first request of the day e.g. `?firstHit=1`
  			//   this allows us to get an estimated count of active users without storing
  			//   any personally identifiable data
  			//
  			// No other data is sent. For more info contact privacy at kuroku.io
