問題：
go get olang.org/x/net/context
package golang.org/x/net/context: unrecognized import path "golang.org/x/net/context" (https fetch: Get https://golang.org/x/net/context?go-get=1: dial tcp 216.58.221.241:443: i/o timeout)
go get 的過程分兩步
- 從版本庫中下載包
-
go install安裝包
定位：是由于有些包國內下載不了
解決辦法：設置代理
export http_proxy='http://name:password@x.x.x.x:xx'
export https_proxy=$http_proxy
