Go dependency management tool
dep: version : devel build date : git hash : go version : go1.10 go compiler : gc platform : linux/amd64
Latest release
爲v0.4.1
linux
go get -u github.com/golang/dep/cmd/dep
若$GOPATH/bin
不在PATH
下,則須要將生成的dep
文件從$GOPATH/bin
移動至$GOBIAN
下git
$ dep Dep is a tool for managing dependencies for Go projects Usage: "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 information Examples: 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.
在項目根目錄執行初始化命令,dep
在初始化時會分析應用程序所須要的全部依賴包,得出依賴包清單github
並生成vendor
目錄,Gopkg.toml
、Gopkg.lock
文件golang
$ dep init -v
直接從對應網絡資源處下載json
$ dep init -gopath -v
該命令會先從$GOPATH
查找既有的依賴包,若不存在則從對應網絡資源處下載安全
該文件由dep init
生成,包含管理dep
行爲的規則聲明網絡
required = ["github.com/user/thing/cmd/thing"] ignored = [ "github.com/user/project/pkgX", "bitbucket.org/user/project/pkgA/pkgY" ] [metadata] key1 = "value that convey data to other systems" system1-data = "value that is used by a system" system2-data = "value that is used by another system" [[constraint]] # Required: the root import path of the project being constrained. name = "github.com/user/project" # Recommended: the version constraint to enforce for the project. # Note that only one of "branch", "version" or "revision" can be specified. version = "1.0.0" branch = "master" revision = "abc123" # Optional: an alternate location (URL or import path) for the project's source. source = "https://github.com/myfork/package.git" # Optional: metadata about the constraint or override that could be used by other independent systems [metadata] key1 = "value that convey data to other systems" system1-data = "value that is used by a system" system2-data = "value that is used by another system"
該文件由dep ensure
和dep init
生成,包含一個項目依賴關係圖的傳遞完整快照,表示爲一系列[[project]]
節ide
# 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"
從項目中的Gopkg.toml
和Gopkg.lock
中分析關係圖,並獲取所需的依賴包工具
用於確保本地的關係圖、鎖、依賴包清單徹底一致jsonp
# 引入該依賴包的最新版本 dep ensure -add github.com/pkg/foo # 引入具備特定約束(指定版本)的依賴包 dep ensure -add github.com/pkg/foo@^1.0.1
將Gopkg.lock
中的約定依賴項更新爲Gopkg.toml
容許的最新版本
目前dep
還在官方試驗階段,但已表示生產可安全使用
若是出現什麼問題,你們能夠一塊兒留個言討論討論
