问题：
Looking how actively golang packages grow and improve I wonder how the problem with package versions is solved?看看 golang 包如何积极地增长和改进，我想知道包版本的问题是如何解决的？
I see that one way is to store third-party packages under a project folder.我看到一种方法是将第三方包存储在项目文件夹下。
But what if I install it with go get ?但是如果我用go get安装它呢？
