装好vim-go插件后，本可以在vim中使用:GoInstallBinaries来安装各种依赖。
但可能网络不好使，需要go设置好7牛的代理来命令行安装包.

下载

golang官网已可以从中国访问，地址:The Go Programming Language
下载对应平台的bin包(源码编译需要golang1.4以上),并解压。

$ wget https://golang.google.cn/dl/go1.18.linux-arm64.tar.gz
$ tar zxvf go1.18.linux-arm64.tar.gz

golang path 库不适配win，用path/filepath替代

坑

now1 := time.Now()
time.Sleep(18 * time.Microsecond)
now2 := time.Now()
fmt.Println(now2.Sub(now1))
