Go + VsCode 环境配置详解

1. 下载并安装

• Git https://gitforwindows.org/
• Go https://golang.google.cn/dl/
• VsCode https://golang.google.cn/dl/

2. 配置GOPATH

• 自定义创建GOPATH目录，例如：D:\SoftWare\Go\workplace，并在该目录下创建src、pkg、bin三个文件夹
• 环境变量GOPATH
  
• 打开控制台(win+r,输入cmd，按回车)，输入 go env 查看go配置信息
  

3. VsCode 配置

• 安装Go扩展
  
• 修改settings.json文件
  
  
• 粘贴以下代码

{
    "workbench.colorTheme": "Default Light+",
    "go.alternateTools": {
        "editor.wordWrap": "on",
        // 如果useLanguageServer设为true，那么在编写代码时引入本地没有的package时，会自动下载安装
        // 就是有时候会非常卡，保存go的编码文件时偶尔会卡死。这点你们自己取舍吧
        "go.useLanguageServer": false,
        "editor.minimap.renderCharacters": false,
        "editor.minimap.enabled": false,
        "terminal.external.osxExec": "iTerm.app",
        "go.docsTool": "gogetdoc",
        "go.testFlags": ["-v","-count=1"],
        "go.buildTags": "",
        "go.buildFlags": [],
        "go.lintFlags": [],
        "go.vetFlags": [],
        "go.coverOnSave": false,
        "go.useCodeSnippetsOnFunctionSuggest": false,
        "go.formatTool": "goreturns",
        "go.gocodeAutoBuild": false,
        "go.goroot": "填写GOROOT路径",
        "go.gopath": "填写GOPATH路径",
        "go.autocompleteUnimportedPackages": true,
        "go.formatOnSave": true,
        "window.zoomLevel": 0,
        "debug.console.fontSize": 16,
        "debug.console.lineHeight": 30,
    }
}

• 创建Go文件
  
• 安装 Go 依赖
  1. 修改 Go 国内镜像
     go env -w GOPROXY=https://goproxy.cn,direct
  2. 安装依赖

     1. 自动安装

        1. Windows平台按下Ctrl+Shift+P
        2. 输入框中输入>go:install，下面会自动搜索相关命令，我们选择 Go:Install/Update Tools 这个命令
        3. 选中所有并回车
        4. 弹出
        5. 等待即可

     2. 手动安装

        1. 到 GOPATH 目录下创建 golang.org/x 目录
        2. 然后在 golang.org/x 路径下启动 CMD 或者 Git Bash
        3. 执行命令

        git clone http://github.com/golang/tools
        git clone http://github.com/golang/lint
        git clone http://github.com/golang/net
        git clone http://github.com/golang/text
        git clone http://github.com/golang/crypto
        git clone http://github.com/golang/sys		
        

        4. 进入GOPATH目录，执行以下命令：

        go get -u -v github.com/nsf/gocode
        go get -u -v github.com/sqs/goreturns
        go get -u -v github.com/golang/lint/golint
        go get -u -v github.com/newhook/go-symbols
        go install golang.org/x/tools/cmd/guru
        go install golang.org/x/tools/cmd/gorename
        go get -u -v github.com/rogpeppe/godef
        go get -u -v github.com/lukehoban/go-outline
        go get -u -v github.com/derekparker/delve/cmd/dlv
        

4. F5 调试运行

• lanuch.json 文件配置

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "GoLaunch",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "remotePath": "",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "${fileDirname}//main.go",	  // 将 main.go 换成你的文件名
            "env": {
                "GOPATH": "D:/SoftWare/Go/workplace/",    // 你的GOPATH
                "GOROOT": "D:/SoftWare/Go/"	// GOROOT，GO的安装目录
            },
            "args": [],
            //"showLog": true
        }
    ]
}
