grunt-contrib-connect |根路径必须是使用的字符串

Question

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.
TypeError: root path must be a string

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
        }
    }
}

我已经尝试过卸载并安装npm包，但到目前为止还没有成功。

有人能指出，我到底遗漏了什么吗？

Answer 1

我的中间件函数中的options.base似乎变成了一个数组，因为我已经将npm包grunt-contrib-connect更新为最新的0.10.1。

我不得不修改代码片段：

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

它必须是一个数组，并且它应该开始工作：

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

希望它也能帮助到一些人！
