Golang 解决 golang.org/x/ 下包下载不下来的问题

软链接

git clone https://github.com/golang/sys.git $GOPATH/src/github.com/golang/sys
git clone https://github.com/golang/net.git $GOPATH/src/github.com/golang/net
git clone https://github.com/golang/text.git $GOPATH/src/github.com/golang/text
git clone https://github.com/golang/lint.git $GOPATH/src/github.com/golang/lint
git clone https://github.com/golang/tools.git $GOPATH/src/github.com/golang/tools
git clone https://github.com/golang/crypto.git $GOPATH/src/github.com/golang/crypto

ln -s $GOPATH/src/github.com/golang/ $GOPATH/src/golang.org/x

手工创建

go env 查看 go path
进入或创建目录：
$GOPATH/src/golang.org/x
进入目录，git clone github.com上项目代替

git clone https://github.com/golang/sys.git 
git clone https://github.com/golang/net.git 
git clone https://github.com/golang/text.git 
git clone https://github.com/golang/lint.git 
git clone https://github.com/golang/tools.git 
git clone https://github.com/golang/crypto.git
