运行 Grunt 任务时，出现以下错误。

Running "connect:client" (connect) task
Warning: root path must be a string Use --force to continue.

Grunt 任务如下：

connect: {
    client: {
        options: {
            // The server's port, and the folder to serve from:
            // Ex: 'localhost:9000' would serve up 'client/index.html'
            port: 9000,
            // change this to '0.0.0.0' to access the server from outside
            hostname: 'localhost',
            base: '<%= jsb.app %>',
            // Custom middleware for the HTTP server:
            // The injected JavaScript reloads the page.
            middleware: livereloadMiddleware
        }
    }
}

已尝试卸载并安装 npm 包，但到目前为止没有运气。

有人可以指出，我到底在这里想念什么？

似乎options.base我的中间件函数正在变成一个数组，因为我已将 npm 包更新grunt-contrib-connect为最新的0.10.1.

必须更改代码段：

connect.static(options.base),
// Make empty directories browsable.
connect.directory(options.base)

它必须是一个数组，它应该开始工作：

connect.static(options.base[0]),
// Make empty directories browsable.
connect.directory(options.base[0])

希望它也对某人有所帮助！
