golang The "gopls" command is not available. Use "go get -v golang.org/x/tools/cmd/gopls" to install.

vscode启动，出现下面提示，点安装会失败。 

The "gopls" command is not available. Use "go get -v golang.org/x/tools/cmd/gopls" to install.

下面是手工解决方案：

github.com中对应golang.org/x/tools/的路径：

https://github.com/Go-zh/tools.git 

git clone ,如果慢，就直接下载ZIP吧。

然后解压到： $GOPATH/src/github.com/Go-zh/tools

gopls路径为:$GOPATH/src/github.com/Go-zh/tools/cmd/gopls

然后安装就行了：

cd $GOPATH/src
go install github.com/Go-zh/tools/cmd/gopls
