1、环境变量

GOROOT 指定SDK安装目录根
Path bin目录
GOPATH 工作目录

2、默认go env

查看

go env GOOS

set AR=ar
set CC=gcc
set CGO_CFLAGS=-O2 -g
set CGO_CPPFLAGS=
set CGO_CXXFLAGS=-O2 -g
set CGO_ENABLED=0
set CGO_FFLAGS=-O2 -g
set CGO_LDFLAGS=-O2 -g
set CXX=g++
set GCCGO=gccgo
set GO111MODULE=
set GOAMD64=v1
set GOARCH=amd64
set GOAUTH=netrc
set GOBIN=
set GOCACHE=C:\Users\MOREFINE\AppData\Local\go-build
set GOCACHEPROG=
set GODEBUG=
set GOENV=C:\Users\MOREFINE\AppData\Roaming\go\env
set GOEXE=.exe
set GOEXPERIMENT=
set GOFIPS140=off

set GOTOOLDIR=C:\Program Files\Go\pkg\tool\windows_amd64
set GOVCS=
set GOVERSION=go1.25.5
set GOWORK=
set PKG_CONFIG=pkg-config

3、编译

# 编译
go build main.go
# 指定输出文件名
go build -o m.exe main.go

编译X86平台

set GOARCH=amd64
set GOOS=linux
set CGO_ENABLED=0
go build -o main_amd64 main.go

编译ARM平台

set GOARCH=arm64
set GOARM=v8.0
set GOOS=linux
set CGO_ENABLED=0
go build -o main_arm64 main.go

4、配置vscode开发环境

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

安装vscode的Go扩展

有条件的要FQ，要从github上下载。在vscode界面按键盘 ctrl+shift+p，输入 Go: install/update tools，回车如下图，选择要安装的依赖（这里全选），等待安装完成。

调试环境

工作目录：D:\00_develop\ycx-study\ycx-go

项目目录：D:\00_develop\ycx-study\ycx-go\src\p1

初始化mod，在p1目录下执行

go mod init github.com/ycx/p1

vscode打开p1目录，F5开始调试，F10单步，F11进入

在.vscode目录下添加launch.json文件

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Package",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${workspaceRoot}",
            "args": ["-config", " server.json"],
            "cwd": "${workspaceRoot}",
            "buildFlags": "-tags 'server'",
        }
    ]
}

5、环境变量

PowerShell

临时设置

$env:VariableName = "Value"

永久设置

# 用户变量
[System.Environment]::SetEnvironmentVariable("VariableName", "Value", "User")

#系统变量
[System.Environment]::SetEnvironmentVariable("VariableName", "Value", "Machine")

所有环境变量

Get-ChildItem Env:
gci Env:

特定环境变量

$env:Path
Get-Item Env:Path

CMD

临时设置

set VariableName=Value

永久设置

# 用户变量
setx VariableName Value

# 系统变量
setx /M VariableName Value

所有环境变量

set

特定环境变量

echo %Path%
