英文:
What does the `...` mean in go get
问题
在这种情况下，...表示通配符，用于匹配指定路径下的所有子包。执行go get github.com/constabulary/gb/...命令将会下载并安装github.com/constabulary/gb包及其所有子包。
英文:
I wanted to install gb
The installation steps says to execute the command:
go get github.com/constabulary/gb/...
What does the ... mean in this case?

...（省略号）告诉go get命令还要获取包的子包/依赖项。
根据go help packages的说明：
如果导入路径包含一个或多个“...”通配符，则它是一个模式，每个通配符可以匹配任何字符串，包括空字符串和包含斜杠的字符串。这样的模式会扩展为在GOPATH树中找到的与模式匹配的所有包目录。作为一个特例，x/...也会匹配x及其子目录。例如，net/...会扩展为net以及其子目录中的包。
关于如何使用它的示例，请参考这个答案。
英文:
The ... (ellipsis) tells go get to also fetch the package's subpackages/dependencies.
From go help packages:
> An import path is a pattern if it includes one or more "..."
> wildcards, each of which can match any string, including the empty
> string and strings containing slashes. Such a pattern expands to all
> package directories found in the GOPATH trees with names matching the
> patterns. As a special case, x/... matches x as well as x's
> subdirectories. For example, net/... expands to net and packages in
> its subdirectories.
