個人心得：
國外翻牆無法連線下載時，用gopm下載方法
先安裝gopm，gopm的安裝網路不影響！
go get -v https://github.com/gpmgo/gopm
然後用gopm來下載其他應用
gopm get -g -v -u github.com/nsf/gocode
gopm get -g -v -u github.com/golang/lint/golint
gopm get -g -v -u github.com/lukehoban/go-outline
gopm get -g -v -u sourcegraph.com/sqs/goreturns
gopm get -g -v -u golang.org/x/tools/cmd/gorename
gopm get -g -v -u github.com/tpng/gopkgs
gopm get -g -v -u github.com/newhook/go-symbols
gopm get -g -v -u golang.org/x/tools/cmd/guru
gopm get -g -v -u golang.org/x/tools/cmd/goimports
gopm get -g -v -u github.com/rogpeppe/godef
下載完畢之後，進入gopath路徑來逐步安裝！
