go get时遇到超时错误

go: golang.org/x/[email protected]: unrecognized import path "golang.org/x/sync" (https fetch: Get https://golang.org/x/sync?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)

go: golang.org/x/[email protected]: unrecognized import path "golang.org/x/net" (https fetch: Get https://golang.org/x/net?go-get=1: dial tcp 216.239.37.1:443: i/o timeout)

go环境变量

export GOROOT=/usr/local/go

export GOPATH=/root/go

export PATH=$PATH:$GOROOT/bin

GOROOT为安装目录   GOPATH为工作目录

golang 在 github 上建立了一个镜像库，下载github上的镜像库放入GOPATH下即可

mkdir -p $GOPATH/src/golang.org/x
cd $GOPATH/src/golang.org/x
git clone https://github.com/golang/net.git
git clone https://github.com/golang/sync.git

项目放在$GOPATH/src

执行go get即可成功
