vscode默认会提示安装缺少的插件，但有些插件需要翻墙，需要手动安装。
不需要翻墙的可直接go get，否则需要手动下载对应的插件包，放到系统GOPATH/src下，
并建立对应的目录结构，执行go install
go install http://github.com/nsf/gocode
go install http://github.com/rogpeppe/godef
go install http://github.com/zmb3/gogetdoc
go install http://github.com/golang/lint/golint
go install http://github.com/lukehoban/go-outline
go install http://sourcegraph.com/sqs/goreturns
go install http://golang.org/x/tools/cmd/gorename
go install http://github.com/tpng/gopkgs
go install http://github.com/newhook/go-symbols
go install http://github.com/cweill/gotests/...
go install http://golang.org/x/tools/cmd/guru
//如果需要在vscode中调试go程序，需要下载安装dlv
