随处创建项目 使用go.mod可以使项目不依赖go path固定目录

完整创建项目详解

• 详细操作
  1. 创建文件

     mkdir SM
     cd SM && touch main.go
     go mod init SM
     go mod tidy
     mkdir -p ./ch3/model/test && cd ./ch3/model/test && touch t.go

  2. t.go

     package test
     
     import "fmt"
     
     func T() {
       fmt.Println("T方法")
     }

  3. main.go

     test.T()

  4. 保存将会自动引入包
  5. 打包

     go build -ldflags "-s -w" -o main
