Question

我是ruby on rails的新手，当我输入rails server命令时，我收到一条奇怪的消息，我不知道如何处理。

Using tzinfo-data 1.2015.7
Using uglifier 2.7.2
Using web-console 2.2.1
Bundle complete! 12 Gemfile dependencies, 53 gems now installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.

Answer 1

看起来你已经安装了nokogiri但是错误版本的ruby。它是为ruby 2.2.0安装的，但你使用的是ruby 2.2.3。

添加这两个文件：

.ruby-宝石

override func viewDidLoad() {
        super.viewDidLoad()

        UIApplication.sharedApplication().idleTimerDisabled = true
        self.navigationController?.navigationBarHidden = true
        let scene = SceneClass(fileNamed: "xxxxxxxx.sks");
        self.view = SKView();

        let skView = self.view as! SKView

        /* Sprite Kit applies additional optimizations to improve rendering performance */
        skView.ignoresSiblingOrder = true
        scene!.cockViewController = self;

        /* Set the scale mode to scale to fit the window */
        scene!.scaleMode = .Fill

        scene!.view?.autoresizesSubviews = true;
        scene?.delegates = self
        skView.presentScene(scene)

    }

.ruby版本

rails4.2.4

然后运行：

ruby-2.2.3

新的rails卡住了rails服务器命令
