1、Go的安装

Go最新版安装包的下载(Go官网):https://studygolang.com/dl

WindowsMacOSnextLinuxLinuxgo/usr/local
go version

2、Go环境变量的配置

安装成功后,必须要配置环境变量。

(1) windows环境变量的配置:

windowsgogopathPathgo
GOROOTGo
GOROOT
GOPATHgo
GoGo_Workssrcpkgbin
GOPATHGoGo_Works

(2) 打开GoMOD,配置代理

在这里感谢「七牛云」为我们中国区的Golang开发者提供的代理服务

打开cmd命令窗,分别运行:

go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct
vscodevscode

(3) 在VSCode中安装Go插件

Extensionsgo$GOPATH/srchello/hello.govscode
$GOPATHD:\Program Files\Go_Works$GOPATHD:\Program Files\Go_Works
$GOPATH/srcD:\Program Files\Go_Works/src
Govscodego

(5) Go Modules的使用

Go modGOPATHGoGOPATHGo modnpm

常用命令为

go mod tidy

通俗来说就是将当前的库源码文件所依赖的包,全部安装并记录下来,多的包就删掉,少了的就自动补上

(6) 实例操作

hellogo mod init
cd $GOPATH/src/hello
go mod init
go.modgo.sum
go.mod
hellogo modgo mod tidy
go help mod
vscodelaunch.jsonsetting.json
launch.jsonDebug
{
    "version": "0.2.0",
    "configurations": [{
     "name": "LaunchGo",
     "type": "go",
     "request": "launch",
     "mode": "auto",
     "program": "${fileDirname}",
     "env": {
     // xxx.go脚本的路径为E:/Study_self/go_lesson/src/hello/xxx.go   
     // 修改"GOPATH": "E:/Study_self/go_lesson", 
     // 在xxx.go脚本目录下运行go mod init hello
     "GOPATH": "D:/Program Files/Go_Works", 
     "GOROOT": "D:/Program Files/Go"
     },
     "args": [],
     //"showLog": true
    }
    ]
   }
setting.jsongolangci-lintvscode

将出现红色异常的地方直接删除或者注释即可。之所以保留给你们,是觉得你们可能有些人也会安装相关插件使用

{
 "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": "D:/Program Files/Go",
 "go.gopath": "D:/Program Files/Go_Works",
 "go.autocompleteUnimportedPackages": true,
 "go.formatOnSave": true,
 "window.zoomLevel": 0,

}
