[开发工具]Go工具包手动安装

VSCODE配置go语言环境时被墙怕了，直接手动吧

在GOPATH目录下下载这些工具包

go get -u -v github.com/nsf/gocode	
go get -u -v github.com/uudashr/gopkgs/v2/cmd/gopkgs
go get -u -v github.com/ramya-rao-a/go-outline		
go get -u -v github.com/acroca/go-symbols	 
go get -u -v golang.org/x/tools/cmd/guru	 
go get -u -v golang.org/x/tools/cmd/gorename	
go get -u -v github.com/fatih/gomodifytags		 
go get -u -v github.com/haya14busa/goplay/cmd/goplay	 
go get -u -v github.com/josharian/impl	
go get -u -v github.com/davidrjenni/reftools/cmd/fillstruct	
go get -u -v github.com/rogpeppe/godef	 
go get -u -v golang.org/x/tools/cmd/godoc	
go get -u -v sourcegraph.com/sqs/goreturns		 
go get -u -v github.com/golang/lint/golint	
go get -u -v github.com/cweill/gotests/...	
go get -u github.com/go-delve/delve/cmd/dlv
go get -u -v github.com/zmb3/gogetdoc	 	 
go get -u -v golang.org/x/tools/cmd/goimports

可以加个代理

// 开启代理设置，Go 1.13 以上默认启用，可跳过此步
go env -w GO111MODULE=on

// 设置代理
go env -w GOPROXY=https://goproxy.io,direct
