请问这些错误是怎么回事呀？

Answer 1

golang.org是谷歌的, 所以被墙, 我还能说什么...

搬上知乎的一个答案

第一个方法：

由于这两个网站在 github 上都有一个同步仓库，分别在 http://github.com/golang 和 http://github.com/kubernetes 所以比较笨的方法就是去下载 github 上对应的代码，然后在手动把目录名改回去，这样 golang 就可以认了。但是这种做法一来比较麻烦，二来升级库的时候会很麻烦，三来很多自动化的依赖管理工具就不能用了，所以大的项目并不推荐这么搞。

第二个方法：

glide 算是一个还比较流行的 golang 依赖管理，他提供了一个 mirror 的命令，可以进行自动的 package 地址替换，比如我想下载 http://golang.org/x/net 那么先敲一个

glide mirror set https://golang.org/x/net https://github.com/golang/net --vcs git
可以在 ~/.glide/mirror.yaml 里看到所有进行 mirror 的 pacakge 这样就可以进行自动的地址替换。所有 http://golang.org 和 http://k8s.io 的库都加进来就可在下载的时候进行自动替换了。

不过 glide mirror 有一个问题就是无法正确的处理 subpackage 比如我想下载 http://golang.org/x/net/http2 这个 mirror 就没有办法设置了，设置成 http://github.com/golang/net 会把这个项目覆盖到 http2 目录，设置为 http://github.com/golang/net/... 又会报找不到 vcs 文件信息。

第三个方法：

也就是终极方法，使用一个我国程序员 patch 过的一个 glide 版本（大概国外人都没这个需求），给 mirror 命令新加了一个 base 参数，上面的例子通过 glide mirror set https://golang.org/x/net/http2 https://github.com/golang/net --base golang.org/x/net --vcs git 就可以解决了
具体的配置信息可以点击xkeyideal/glide，看看作者自己的一个 README。

希望经过这番折腾，可以让你写代码的时候心情好一点点。
