Ionic 2 CLI构建失败给我以下错误:" TypeError:无法读取属性' AssetUrl'未定义"。
我的研究引导我this thread和this one。
两个主题都建议修改" package.json"文件并删除" ^"在"依赖关系"中签署版本。和" devDependencies"。
我做了然后CLI:
我仍然得到同样的错误。
在this thread的某个时刻,它建议使用一些我不熟悉的npm命令,引用它:" rm -rf node_modules和npm cache clean以及新的npm install&#34 ;。 我真的不明白所有这些内容是什么。
如果有人拿出神奇的解决方案让构建运行正常,我将不胜感激。但我也想了解如何" TypeError:无法读取属性' AssetUrl'未定义"可以与" package.json"?链接?我不知道为什么这个错误会导致这种可能的解决方案。
我的版本是: npm 3.10.3 节点6.7.0 科尔多瓦6.3.1 离子2.1.0
这是我的package.json,因为它现在看起来更像是在两个线程中读取建议:

我在CLI中的项目文件夹中执行了" npm install" +带走" ^"签署"依赖"和" devDependencies"在package.json中(在我的问题中链接的论坛帖子中建议)。它解决了它。

您还应该将@ angular / compiler-cli更新为最新版本。
