【中文标题】在 Bluemix 上使用 MobileFirst Services Starter 创建应用程序

【英文标题】：Creating an application with MobileFirst Services Starter on Bluemix

【问题描述】：

我正在学习教程：https://www.ibm.com/developerworks/library/mo-android-mobiledata-app/index.html

当应用程序启动时，它立即被阻塞并停止运行。

在活动信息频道出现如下信息：

应用实例已被阻止：发生 2 个错误：* 发生 2 个错误：* Exited with stat...

默认情况下我已经保留了所有内容，并且我在不同的地区（美国南部、英国……）进行了尝试，并且行为是相同的……

我不知道是什么问题。

问候

【问题讨论】：

@atanony 您指的是开发者作品中的旧博客，您能否通过以下 youtube 链接和 github 链接了解有关如何使用 android 应用程序进行推送通知的更多信息。 youtube.com/watch?v=Fza8kj74Lqsgithub.com/ibm-bluemix-mobile-services/…

@pradeep-sg 感谢您的评论和链接。

我能够重现该问题。我在日志中得到的错误是这样的：

这是因为在 Node.js 0.12 中默认未启用 ES6 导致的错误。正如@pradeep sg 所说，该博客文章和启动器已经过时了。如果您查看启动器的代码，它会在 package.json 中指定 Node 版本 0.12。

要为您的本地环境解决此问题，请下载起始代码，然后修改 package.json，如下所示：

  "name": "HelloTodo",
  "description": "A simple todo list application created with StringLoop, LoopBack and Bluemix Mobile Services",
  "version": "1.0.0",
  "main": "server/server.js",
  "scripts": 
    "start": "node ."
  ,
  "author": "Anton Aleksandrov",
  "dependencies": 
    "bluemix-appid": "1.x",
    "compression": "^1.0.3",
    "cors": "^2.5.2",
    "loopback": "^2.22.0",
    "loopback-boot": "^2.6.5",
    "loopback-component-explorer": "^2.1.0",
    "loopback-connector-mysql": "^2.2.0",
    "loopback-datasource-juggler": "^2.39.0",
    "passport": "^0.3.2",
    "serve-favicon": "^2.0.1"
  ,
  "repository": 
    "type": "git",
    "url": "https://github.com/ibm-bluemix-mobile-services/bms-hellotodo-strongloop.git"
  ,
  "engines": 
    "node": "8.9.x"
  ,
  "license": "Apache-2.0"

然后做一个bx cf push重新部署，所以它使用了一个更新的Node引擎。

在我这样做之后，它起作用了：

如果您想查找移动团队正在制作的最新内容，请在此处查看他们在 Bluemix 上的仪表板：

这将提供最新的入门工具包、演示、博客和他们正在发布的内容。

我会通知他们这个问题，以便部署正常工作。
