問題：
Looking how actively golang packages grow and improve I wonder how the problem with package versions is solved?看看 golang 包如何積極地增長和改進，我想知道包版本的問題是如何解決的？
I see that one way is to store third-party packages under a project folder.我看到一種方法是將第三方包存儲在項目文件夾下。
But what if I install it with go get ?但是如果我用go get安裝它呢？
