windows上用了vendor目录后为什么会这样？

..\src\Handlers\HandleRoot.go:4:2: cannot find package "_/D_/work/GoPath/src/Server/vendor/github.com/gin-gonic/gin" in any of: C:\Go\src\_\D_\work\GoPath\src\Server\vendor\github.com\gin-gonic\gin (from $GOROOT) D:\work\GoPath\src\_\D_\work\GoPath\src\Server\vendor\github.com\gin-gonic\gin (from $GOPATH) 如上，在vendor目录全路径前加GOROOT或GOPATH后再去搜索包？？？？直接忽略了vendor目录本身？
