## 环境配置 当你的 Golang 安装完成后,需要检查以下环境变量是否配置正确: - `$GOPATH` 配置 go 的工作目录 - `$PATH` 将 $GOPATH/bin 目录加入该环境变量,可以直接执行安装的命令 - `$GO111MODULE` 配置 "on" 开启 go mod - `$GOPROXY` 配置 "https://goproxy.io" 开启代理 配置完成后查看配置结果: ~~~ $> go env GO111MODULE="on" GOARCH="amd64" GOBIN="/Users/***/golang/bin" GOCACHE="/Users/***/Library/Caches/go-build" GOENV="/Users/***/Library/Application Support/go/env" GOEXE="" GOFLAGS="" GOHOSTARCH="amd64" GOHOSTOS="darwin" GONOPROXY="" GONOSUMDB="" GOOS="darwin" GOPATH="/Users/***/golang" GOPRIVATE="" GOPROXY="https://goproxy.io" GOROOT="/usr/local/go" GOSUMDB="sum.golang.org" GOTMPDIR="" GOTOOLDIR="/usr/local/go/pkg/tool/darwin_amd64" GCCGO="gccgo" AR="ar" CC="clang" CXX="clang++" CGO_ENABLED="1" GOMOD="/Users/***/***/go.mod" 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=/var/folders/gw/f8fnsvhj3dgcsgyz9vfx28040000gn/T/go-build030193521=/tmp/go-build -gno-record-gcc-switches -fno-common" ~~~
