sudo vim /etc/profile
11 export GOROOT=/usr/local/go
12 export GOPATH=${GOROOT}/gopath
13 export PATH=$PATH:${GOROOT}/bin
14 export GO111MODULE=on
15 export GOPROXY=https://goproxy.cn
source /etc/profile
说明:
1. GOROOT 为go安装目录, 在mac下使用pkg包安装的, 目录为 /usr/loca/go
如果用go mod gopath 设置为/usr/local/go/gopath
