错误从ng2.0.0-beta.0移至ng2.0.0-beta.7 [英] errors moving from ng2.0.0-beta.0 to ng2.0.0-beta.7
问题描述
我有一个配置了ng2.0.0-beta.0软件包的apache cordova打字稿项目，并且已成功启动，请参见下面的package.json和javascript控制台输出.
I have an apache cordova typescript project with ng2.0.0-beta.0 package configured and successfully working on startup, see package.json and javascript console output below.
我正尝试移至该项目中的当前ng2.0.0-beta.7软件包，以查看它是否解决了意外问题，当我更改模板引用的类成员变量时，视图未更新，有关详细信息，请参见" cordova应用程序角度2成员变量未更新正在更新对其的模板引用".
I was attempting to move to the current ng2.0.0-beta.7 package in that project to see if it address an unexpected issue I am experiencing where views are not updating when template referenced class member variables changed, for details see "cordova app angular 2 member variable update not updating template reference to it".
当我切换到ng2.0.0-beta.7软件包时，一切都可以正常编译，但是ng2无法成功启动，请参见下面的package.json和javascript控制台输出.
When I switch to ng2.0.0-beta.7 package everything transpiles fine but ng2 doesn't successfully startup, see package.json and javascript console output below.
我在 https://github的主分支中对ng2.0.0-beta.0的情况进行了复制.com/myusrn/acu6withng2 和ng2.0.0-beta.7在acu6withng27主题分支https://github.com/myusrn/acu6withng2/tree/acu6withng27 .
I have repro for the ng2.0.0-beta.0 case in master branch of https://github.com/myusrn/acu6withng2 and ng2.0.0-beta.7 case in acu6withng27 topic branch https://github.com/myusrn/acu6withng2/tree/acu6withng27.
任何人都看到过ng2.0.0-beta.7出现此运行时错误，如果是的话，是由于我忽略了某些步骤还是有已知的解决方法?
Anyone seen this runtime error with ng2.0.0-beta.7 and if so is it due to some step i'm overlooking or perhaps there is a known fix for it?

推荐答案
我找到了解决方案，该解决方案涉及将以下内容简单地添加到index.html脚本标签列表中，并使用新的ng 2.0.0-beta.8软件包作为好吧.
I found a resolution to this which involved simply adding the following to index.html script tags list and worked with new ng 2.0.0-beta.8 package as well.
<script src="node_modules/reflect-metadata/Reflect.js"></script>
由于此详细信息不属于当前 https://angular.io/guide/quickstart 我不确定差异是否是我的hello world项目环境存在问题，还是需要添加到index.html脚本标记中应包含的内容的快速入门笔记中.
Since this detail isn't a part of the current https://angular.io/guide/quickstart I'm not sure if the difference is a problem with my hello world project environment or a detail that needs to get added to quickstart notes on what should go in index.html script tags.
