go:遠程包安裝問題

在使用go get安裝gopls時發現連接超時，錯誤如下：

命令

go get golang.org/x/tools/gopls

輸出

package golang.org/x/sync/errgroup: unrecognized import path "golang.org/x/sync/errgroup" (https fetch: Get https://golang.org/x/sync/errgroup?go-get=1: dial tcp 216.239.37.1:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.)

解決方案

由於golang.org/x在github/golang下有鏡像文件，故手動在$GOPATH/src目錄創建golang.org/x子目錄，並進入目錄中，clonegithub/golang下的倉庫。

git clone https://github.com/golang/gopls
