vscode设置go环境

1. 下载 Vs Code

2. 下载 Go 环境

3. 配置 go 环境变量
   3.1 配置 GOROOT（Go安装路径in）
   3.2 配置 GOPATH（Go工作区）
   

4. 新建hello.go文件用vs code打开

   package main
   import (
       "fmt"
   )
   
   func main() {
       fmt.Println("Hello World!") 
   }
   

   vscode会提示你安装go插件 点击 install all 会安装失败 (被墙了)
   

   安装Go插件，就这一个就可以

   安装Go语言开发工具包 ctrl+Shift+P
   输入框中输入go:install 会自动搜索相关命令，选择Go:Install/Update Tools
   

5. 安装失败解决办法：

   1. 在GOPATH的src目录下创建golang.org/x目录

   2. 在GOPATH/src/golang.org/x目录下

   3. 执行 git clone https://github.com/golang/tools.git tools命令

   4. 执行 git clone https://github.com/golang/lint.git 命令

   5. 按下Ctrl/Command+Shift+P再次执行 Go:Install/Update Tools 命令，在弹出的窗口全选并点击确定，这一次的安装都会SUCCESSED了

      git clone https://github.com/golang/tools.git tools
      go install github.com/ramya-rao-a/go-outline
      go install github.com/acroca/go-symbols
      go install golang.org/x/tools/cmd/guru
      go install golang.org/x/tools/cmd/gorename
      go install github.com/josharian/impl
      go install github.com/rogpeppe/godef
      go install github.com/sqs/goreturns
      go install github.com/golang/lint/golint
      go install github.com/cweill/gotests/gotests
      go install github.com/ramya-rao-a/go-outline
      go install github.com/acroca/go-symbols
      go install golang.org/x/tools/cmd/guru
      go install golang.org/x/tools/cmd/gorename
      go install github.com/josharian/impl
      go install github.com/rogpeppe/godef
      go install github.com/sqs/goreturns
      go install github.com/golang/lint/golint
      go install github.com/cweill/gotests/gotests

6. 安装失败解决办法 使用go mod 代理安装

   # Go 1.13 及以上（推荐）
   
   # Windows执行
   go env -w GO111MODULE=on
   go env -w GOPROXY=https://goproxy.io,direct
   
   # Windows PowerShell 执行 
   $env:GO111MODULE = "on"
   $env:GOPROXY = "https://goproxy.cn"
   
   # macOS 或 Linux 执行
   export GO111MODULE=on
   export GOPROXY=https://goproxy.cn
   
   # 或者  macOS 或 Linux 执行
   echo "export GO111MODULE=on" >> ~/.profile
   echo "export GOPROXY=https://goproxy.cn" >> ~/.profile
   source ~/.profile
   
   
   // 手动安装
   go get -u -v github.com/mdempsky/gocode
   go get -u -v github.com/uudashr/gopkgs/v2/cmd/gopkgs
   go get -u -v github.com/ramya-rao-a/go-outline
   go get -u -v github.com/acroca/go-symbols
   go get -u -v golang.org/x/tools/cmd/guru
   go get -u -v golang.org/x/tools/cmd/gorename
   go get -u -v github.com/cweill/gotests/...
   go get -u -v github.com/fatih/gomodifytags
   go get -u -v github.com/josharian/impl
   go get -u -v github.com/davidrjenni/reftools/cmd/fillstruct
   go get -u -v github.com/haya14busa/goplay/cmd/goplay
   go get -u -v github.com/godoctor/godoctor
   go get -u -v github.com/go-delve/delve/cmd/dlv
   go get -u -v github.com/stamblerre/gocode
   go get -u -v github.com/rogpeppe/godef
   go get -u -v github.com/sqs/goreturns
   go get -u -v golang.org/x/lint/golint
   

7. 项目下执行：go mod init 项目名 生成 go.mod

8. vscode配置go环境
   文件–>首选项–>设置

   {
    "go.buildOnSave": true,
    "go.buildFlags": [],
    "go.buildTags": "",
    "go.lintOnSave": true,
    "go.formatOnSave": true,
    "go.gopath": "E:\gohmoe",
    "go.goroot": "C:\go"
   }
   

   
   执行：go run 文件名
   或者设置F5 launch.json里添加

   {
       "version": "0.2.0",
       "configurations": [
           {
               "name": "LaunchGo",
               "type": "go",
               "request": "launch",
               "mode": "auto",
               "remotePath": "",
               "port": 5546,
               "host": "127.0.0.1",
               "program": "${fileDirname}",
               "env": {
                   "GOPATH": "E:/GoCode",
                   "GOROOT": "C:/Program Files/Go"
               },
               "args": [],
               //"showLog": true
           }
       ]
   }
   

   按 F5 Debug执行

9. 安装 code runner 插件 执行按钮执 行代码
