[英]Force a specific version for a dependency when using dep
I am using dep to manage the dependencies of a Go tool I'm writing. 我正在使用dep来管理我正在编写的Go工具的依赖项。
This tool uses https://github.com/desertbit/grumble as an dependency. 此工具使用https://github.com/desertbit/grumble作为依赖项。 This in turn uses https://github.com/chzyer/readline as a dependency. 这反过来使用https://github.com/chzyer/readline作为依赖。 The problem is that when trying to run my tool I get the following error: vendor/github.com/desertbit/grumble/app.go:295:20: unknown field 'HistorySearchFold' in struct literal of type readline.Config
问题是,当我尝试运行我的工具时,我收到以下错误: vendor/github.com/desertbit/grumble/app.go:295:20: unknown field 'HistorySearchFold' in struct literal of type readline.Config
I know why this is happending. 我知道为什么会这样。 grumble uses the master branch of readline as a dependency. grumble使用readline的master分支作为依赖。 In this the field HistorySearchFold
is available. 在此,可以使用HistorySearchFold
字段。 When using dep init
/ dep ensure
not the master but the 1.4 tag is pulled into the vendor folder. 使用dep init
/ dep ensure
不是master,而是将1.4标签拉入vendor文件夹。
My question therefore is: How can I force dep to pull the master branch instead? 因此我的问题是:我如何强制dep拉取主分支呢?
I tried adding the following in my Gopkg.toml file: 我尝试在我的Gopkg.toml文件中添加以下内容:
[[constraint]]
branch = "master"
name = "github.com/chzyer/readline"
Sadly this is not working. 可悲的是,这不起作用。 When I check the version pulled into the vendor folder it is still 1.4 . 当我检查拉入供应商文件夹的版本时,它仍然是1.4 。
If you are trying to control the version of a transient dependency (not one directly used by your package, you should use the [[override]]
directive 如果您试图控制瞬态依赖的版本(不是您的包直接使用的版本),您应该使用[[override]]
指令
It looks exactly the same as a constraint, but it will constrain dependencies even when not directly inherited by your package. 它看起来与约束完全相同,但即使不直接由包继承,它也会限制依赖关系。
[[override]]
branch = "master"
name = "github.com/chzyer/readline"
Note that this is also useful for when the dependency solver finds conflicting dependencies, eg your package P makes use of packages A and B, and both depend on different versions of package X... you can use an override on package X inside of your package P 请注意,这对于依赖项解算器发现冲突依赖项时也很有用,例如,包P使用包A和B,并且两者都依赖于包X的不同版本...您可以在包内使用包X上的覆盖包P
