在安装go插件时，会自动更新很多依赖库文件，都是从Github更新下来，但是因为Github的文件中，多有应用go官网中的文件，导致，因为网络缘故，不能直接下载，导致安装失败，如下：

Installing github.com/nsf/gocode SUCCEEDED
Installing github.com/uudashr/gopkgs/cmd/gopkgs SUCCEEDED
Installing github.com/ramya-rao-a/go-outline FAILED
Installing github.com/acroca/go-symbols FAILED
Installing golang.org/x/tools/cmd/guru FAILED
Installing golang.org/x/tools/cmd/gorename FAILED
Installing github.com/fatih/gomodifytags SUCCEEDED
Installing github.com/haya14busa/goplay/cmd/goplay SUCCEEDED
Installing github.com/josharian/impl FAILED
Installing github.com/rogpeppe/godef SUCCEEDED
Installing sourcegraph.com/sqs/goreturns FAILED
Installing github.com/golang/lint/golint FAILED
Installing github.com/cweill/gotests/... FAILED
Installing github.com/derekparker/delve/cmd/dlv SUCCEEDED

8 tools failed to install.

这些失败的库，不是没有下载下来，而是以来的文件在go官网上，导致失败。以下为解决办法，

1、在%GOPATH%\src\ 目录下，建立golang.org 文件夹，并再新建x文件夹。 目录为 "%GOPATH\src\golang.org\x\"

2、完成目录切换后，开始下载插件包：
git clone https://github.com/golang/tools.git tools

3、执行完以后，会多一个tools文件夹。

4、打开vsCode终端，切换到 终端，进入“%GOPATH”目录,执行 

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

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

按此方法，可以安装成功。
