1. dep简介

dep是一个golang项目的包管理工具，一般只需要2-3个命令就可以将go依赖包自动下载并归档到vendor的目录中。dep官网参考：https://github.com/golang/dep

2. dep安装

  1. go get -u github.com/golang/dep/cmd/dep

3. dep使用

  1. #进入到项目目录
  2. cd /home/gopath/src/demo
  3. #dep初始化，初始化配置文件Gopkg.toml
  4. dep init
  5. #dep加载依赖包，自动归档到vendor目录
  6. dep ensure 
  7. # 最终会生成vendor目录，Gopkg.toml和Gopkg.lock的文件

4. dep的配置文件

Gopkg.toml记录依赖包列表。

  27. ignored = ["demo"]
  29. [[constraint]]
  30.   name = "github.com/BurntSushi/toml"
  31.   version = "0.3.0"
