安装

|
go get -u github.com/golang/dep/cmd/dep |
若$GOPATH/bin不在PATH下，则需要将生成的dep文件从$GOPATH/bin移动至$GOBIAN下

$ depDep is a tool for managing dependencies for Go projectsUsage: "dep [command]" Commands: init Set up a new Go project, or migrate an existing one status Report the status of the project's dependencies ensure Ensure a dependency is safely vendored in the project prune Pruning is now performed automatically by dep ensure. version Show the dep version informationExamples: dep init set up a new project dep ensure install the project's dependencies dep ensure -update update the locked versions of all dependencies dep ensure -add github.com/pkg/errors add a dependency to the project Use "dep help [command]" for more information about a command. |
初始化
在项目根目录执行初始化命令，dep在初始化时会分析应用程序所需要的所有依赖包，得出依赖包清单
并生成vendor目录，Gopkg.toml、Gopkg.lock文件
默认初始化
|
1
|
$ dep init -v |
直接从对应网络资源处下载
优先从$GOPATH初始化
|
1
|
$ dep init -gopath -v |
该命令会先从$GOPATH查找既有的依赖包，若不存在则从对应网络资源处下载
Gopkg.toml
该文件由dep init生成，包含管理dep行为的规则声明

Gopkg.lock
该文件由dep ensure和dep init生成，包含一个项目依赖关系图的传递完整快照，表示为一系列[[project]]节

# This file is autogenerated, do not edit; changes may be undone by the next 'dep ensure'. [[projects]] branch = "master" name = "github.com/golang/protobuf" packages = [ "jsonpb", "proto", "protoc-gen-go/descriptor", "ptypes", "ptypes/any", "ptypes/duration", "ptypes/struct", "ptypes/timestamp" ] revision = "bbd03ef6da3a115852eaf24c8a1c46aeb39aa175" |
常用命令
dep ensure
从项目中的Gopkg.toml和Gopkg.lock中分析关系图，并获取所需的依赖包
用于确保本地的关系图、锁、依赖包清单完全一致
dep ensure -add

# 引入该依赖包的最新版本dep ensure -add github.com/pkg/foo # 引入具有特定约束（指定版本）的依赖包dep ensure -add github.com/pkg/foo@^1.0.1 |
dep ensure -update
将Gopkg.lock中的约定依赖项更新为Gopkg.toml允许的最新版本
