我已经完成了所有类似的问题,但没有任何运气。我有一个Ionic 2项目正在我的旧笔记本电脑上运行,其中包含以下详细信息:
Cordova CLI Version: 6.5.0
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 10
Node Version: v4.2.6
Xcode version: Not installed
在我的新笔记本电脑上安装最新的NPM和Ionic后,我通过git克隆了该项目。我遇到了一些我解决的问题。此时,当我运行 ionic serve 时,我的浏览器中会加载一个空白页面,并在控制台中显示以下错误:
Failed to load resource: the server responded with a status of 404 (Not Found)
以下是Ionic 2在我的新笔记本电脑中的样子:
Cordova CLI: 6.5.0
Ionic Framework Version: 2.0.0-rc.4
Ionic CLI Version: 2.2.3
Ionic App Lib Version: 2.2.1
Ionic App Scripts Version: 0.0.47
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 10
Node Version: v7.9.0
Xcode version: Not installed
知道问题是什么,或者我该如何调试呢?

然而,在此之后我收到了存储错误。我用这里的答案解决了这个问题:
Can't resolve all parameters for Storage: (?)
希望这有助于其他人。
