go get -u github.com/gocolly/colly/... 

有些包无法下载，我们通过git来下载

git clone https://github.com/golang/net.git  $GOPATH/src/golang.org/x/net 

git clone https://github.com/golang/text.git  $GOPATH/src/golang.org/x/text     

git clone https://github.com/golang/protobuf.git  $GOPATH/src/github.com/golang/protobuf         

git clone https://github.com/golang/appengine.git $GOPATH/src/google.golang.org/appengine
