## README

# go项目

## step 1
```
➜  mkdir godemo && cd godemo
➜  touch README.md main.go
➜  go mod init godemo
```
## step 2
使用go get安装第三方包
```
➜  go get github.com/satori/go.uuid
```
这个命令会将包安装到系统的GOPATH,并且会修改go.mod和go.sum文件

```
➜  cat go.mod
module godemo

go 1.18

require github.com/satori/go.uuid v1.2.0 // indirect
```
```
➜  cat go.sum
github.com/satori/go.uuid v1.2.0 h1:0uYX9dsZ2yD7q2RtLRtPSdGDWzjeM3TbMJP9utgA0ww=
github.com/satori/go.uuid v1.2.0/go.mod h1:dA0hQrYB0VpLJoorglMZABFdXlWrHn1NEOzdhQKdks0=
```
```
ls ~/go/pkg/mod/github.com/satori/go.uuid@v1.2.0/
LICENSE           codec_test.go     sql.go            uuid_test.go
README.md         generator.go      sql_test.go
codec.go          generator_test.go uuid.go
```

## step 3
直接运行
```
➜  godemo go run main.go
this prints from sys module
this prints from submod.sub1
UUIDv4: eddf906d-aab3-4bf9-9b0f-022ddac48043
```
编译运行
```
➜  godemo go build
➜  godemo ./godemo
this prints from sys module
this prints from submod.sub1
UUIDv4: f9c14e9e-13a5-4541-9058-64b333ab8a23
```
