英文:
how to check 'go get <package>' installation status?
问题
go get 命令有没有选项可以告诉我它是否真的做了什么？
例如，如果包 X 已经安装了，我想知道 go get X 没有执行任何下载/安装操作。
英文:
Is there any option for go get that can tell me whether it actually did anything?
For example, if the package X was already installed, I would like to know that go get X didn't perform any downloading/installation.

使用 go get -v 命令。
下面是一个示例，展示了使用和不使用 go get 命令的区别：
$ go get -v github.com/peak6/envflag
github.com/peak6/envflag (下载) # 下载包
github.com/peak6/envflag # 构建包（我认为）
$ go get -v github.com/peak6/envflag
$ # 无需操作
英文:
Use go get -v
Here's an example of get doing something vs not:
$ go get -v github.com/peak6/envflag
github.com/peak6/envflag (download) # downloaded package
github.com/peak6/envflag # built package (I think)
$ go get -v github.com/peak6/envflag
$ # nothing to do
