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

vscode啟動，出現下面提示，點安裝會失敗。 

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

下面是手工解決方案：

github.com中對應golang.org/x/tools/的路徑：

https://github.com/Go-zh/tools.git 

git clone ,如果慢，就直接下載ZIP吧。

然后解壓到： $GOPATH/src/github.com/Go-zh/tools

gopls路徑為:$GOPATH/src/github.com/Go-zh/tools/cmd/gopls

 

然后安裝就行了：

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