windows - 为什么 "go get gopkg.in/..."不工作而 "go get github.com/..."正常？

Question

我尝试使用go get gopkg.in/fatih/pool.v2 安装pool根据Readme.md，但是无法成功:

C:\Users\xiaona\Documents\GitHub> go get -v gopkg.in/fatih/pool.v2
Fetching https://gopkg.in/fatih/pool.v2?go-get=1
https fetch failed.
Fetching http://gopkg.in/fatih/pool.v2?go-get=1
import "gopkg.in/fatih/pool.v2": http/https fetch: Get http://gopkg.in/fatih/poo
l.v2?go-get=1: dial tcp 107.178.216.236:80: ConnectEx tcp: A connection attempt

me, or established connection failed because connected host has failed to respon
d.
package gopkg.in/fatih/pool.v2: unrecognized import path "gopkg.in/fatih/pool.v2
"

虽然在网络浏览器中访问 107.178.216.236:80 是正常的。

我尝试使用 go get github.com/fatih/pool，它也可以正常工作。

谁能就这个问题提供一些线索？

顺便说一句:我使用 windows powershell 和 git 版本是 1.9.5。

根本原因找到了:因为我的电脑使用了web代理，所以需要在环境变量中设置代理:

C:\Users\xiaona>set https_proxy=https://web-proxy.corp.hp.com:8080/

C:\Users\xiaona>set http_proxy=https://web-proxy.corp.hp.com:8080/

C:\Users\xiaona>go get -v gopkg.in/fatih/pool.v2
Fetching https://gopkg.in/fatih/pool.v2?go-get=1
Parsing meta tags from https://gopkg.in/fatih/pool.v2?go-get=1 (status code 200)

get "gopkg.in/fatih/pool.v2": found meta tag main.metaImport{Prefix:"gopkg.in/fa
tih/pool.v2", VCS:"git", RepoRoot:"https://gopkg.in/fatih/pool.v2"} at https://g
opkg.in/fatih/pool.v2?go-get=1
gopkg.in/fatih/pool.v2 (download)
gopkg.in/fatih/pool.v2

那么，一切就OK了!
