环境变量
GOPATH : D:\code\go
GOROOT : C:\Program Files\Go
Path : %GOPATH%\bin;%GOROOT%\bin;

在GOPATH目录下新建bin、pkg、src三个文件夹

如果使用的ide是vscode 建议重启系统

存放地址：%GOPATH%\src\golang.org\x
https://github.com/golang/tools.git
https://github.com/golang/mod.git
https://github.com/golang/xerrors.git
https://github.com/golang/lint.git

存放地址：%GOPATH%\src下 一级目录是url中的域名，即：github.com
子目录结构同url地址
例如：git clone https://github.com/mdempsky/gocode.git
存放的地址就是%GOPATH%\src\github.com\mdempsky\
