go环境安装

1、在mac终端安装go

在go 官方网站下载mac版本的go,安装完成后在中断运行go version和 go env确认go安装好了

例如我的：

alisadeMacBook-Pro:~ root# go version
go version go1.15.3 darwin/amd64
alisadeMacBook-Pro:~ root# go env
GO111MODULE=""
GOARCH="amd64"
GOBIN=""
GOCACHE="/var/root/Library/Caches/go-build"
GOENV="/var/root/Library/Application Support/go/env"
GOEXE=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="darwin"
GOINSECURE=""
GOMODCACHE="/var/root/go/pkg/mod"
GONOPROXY=""
GONOSUMDB=""
GOOS="darwin"
GOPATH="/var/root/go"
GOPRIVATE=""
GOPROXY="https://proxy.golang.org,direct"
GOROOT="/usr/local/Cellar/go/1.15.3/libexec"
GOSUMDB="sum.golang.org"
GOTMPDIR=""
GOTOOLDIR="/usr/local/Cellar/go/1.15.3/libexec/pkg/tool/darwin_amd64"
GCCGO="gccgo"
AR="ar"
CC="clang"
CXX="clang++"
CGO_ENABLED="1"
GOMOD=""
CGO_CFLAGS="-g -O2"
CGO_CPPFLAGS=""
CGO_CXXFLAGS="-g -O2"
CGO_FFLAGS="-g -O2"
CGO_LDFLAGS="-g -O2"
PKG_CONFIG="pkg-config"
GOGCCFLAGS="-fPIC -m64 -pthread -fno-caret-diagnostics -Qunused-arguments -fmessage-length=0 -fdebug-prefix-map=/tmp/go-build777133695=/tmp/go-build -gno-record-gcc-switches -fno-common"
alisadeMacBook-Pro:~ root#

2、下载安装vscode

查看vscode版本，点击vscode软件左上角的visual studio code查看vscode的版本

 或者在帮助中relase note中查看

 

 3、在vscode 中查找setting.json并且配置一些参数，包括自动导入啊等等

点击左侧的小齿轮，然后选setting

其中Setting内容如下

{

"editor.suggestSelection": "first",

"vsintellicode.modify.editor.suggestSelection": "automaticallyOverrodeDefaultValue",

"workbench.colorTheme": "One Monokai",

"python.languageServer": "Microsoft",

"python.pythonPath": "/usr/local/opt/python/bin/python3.7",

"atomKeymap.promptV3Features": true,

"editor.multiCursorModifier": "ctrlCmd",

"editor.formatOnPaste": true,

"editor.fontSize": 12,

"editor.snippetSuggestions": "top",

"terminal.integrated.shell.osx": "/bin/bash",

"editor.codeActionsOnSave": { "source.organizeImports": true },

"go.autocompleteUnimportedPackages": true,

"go.gocodePackageLookupMode": "go",

"go.gotoSymbol.includeImports": true,

"go.useCodeSnippetsOnFunctionSuggest": true,

"go.useCodeSnippetsOnFunctionSuggestWithoutType": true,

"files.autoSave": "afterDelay",

"go.alternateTools": {

"files.autoSave": "off",

"go.buildOnSave": true,

"go.lintOnSave": true,

"go.vetOnSave": true,

"go.buildFlags": [],

"go.lintFlags": [],

"go.vetFlags": [],

"go.coverOnSave": false,

"go.useCodeSnippetsOnFunctionSuggest": false,

"go.formatOnSave": true,

"go.formatTool": "goreturns",

"go.goroot": "/usr/local/go", //默认/usr/local/-->双引号中一般填写你的goroot路径

"go.gopath": "/Users/mayan/golang_project",//-->一般填写你的gopath路径

} //括号内地内容为新增加

}

4、安装完成后在桌面创建demo文件夹，在demo文件夹中创建main.go，然后在vscode中打开main.go开始写第一个程序
