vscode设置go环境

下载 Vs Code
下载 Go 环境
配置 go 环境变量
3.1 配置 GOROOT（Go安装路径bin）
3.2 配置 GOPATH（Go工作区）
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

安装失败解决办法：

在GOPATH的src目录下创建golang.org/x目录
在GOPATH/src/golang.org/x目录下
执行 git clone https://github.com/golang/tools.git tools命令
执行 git clone https://github.com/golang/lint.git 命令
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

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 github.com/rogpeppe/godef
go get -u -v github.com/sqs/goreturns
go get -u -v golang.org/x/lint/golint

项目下执行：go mod init 项目名生成 go.mod

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",

            "remotePath": "",
            "port": 5546,
            "host": "127.0.0.1",
            "program": "${fileDirname}",
            "env": {
                "GOPATH": "E:/GoCode",
                "GOROOT": "C:/Program Files/Go"
            },
            "args": [],
            //"showLog": true
        }
    ]
}
