前言
从vscode中直接安装go相关插件大部分是失败的，原因你懂得的。参考下面的文章，归纳下执行步骤。
执行步骤
1、定位到如下目录（没有的话就创建）
cd $GOPATH/src/golang.org/x/
2、执行如下命令
git clone https://github.com/golang/tools.git tools
3、执行完成后，定位到$GOPATH目录下，执行以下命令
cd $GOPATH
go install github.com/ramya-rao-a/go-outline
go install github.com/acroca/go-symbols
go install golang.org/x/tools/cmd/guru
go install golang.org/x/tools/cmd/gorename
go install github.com/josharian/impl
go install github.com/rogpeppe/godef
go install github.com/sqs/goreturns
go install github.com/cweill/gotests/gotests
go install github.com/ramya-rao-a/go-outline
go install github.com/acroca/go-symbols
go install golang.org/x/tools/cmd/guru
go install golang.org/x/tools/cmd/gorename
go install github.com/josharian/impl
go install github.com/rogpeppe/godef
go install github.com/sqs/goreturns
go install github.com/golang/lint/golint
go install github.com/cweill/gotests/gotests安装完成后可以愉悦的使用vscode写go了。
