Ionic 2 Build TypeError:无法读取未定义的属性'AssetUrl' [英] Ionic 2 Build TypeError: Cannot read property 'AssetUrl' of undefined
问题描述
Ionic 2 CLI构建失败给我以下错误:TypeError:无法读取属性'AssetUrl'未定义。
Ionic 2 failed CLI build giving me the following error: "TypeError: Cannot read property 'AssetUrl' of undefined".
两个线程都建议修改package.json文件并删除dependencies和devDependencies中版本前面的^符号。
我做了然后CLI:
- ionic rm platform android
- ionic添加平台android
- 最后:离子构建android
我仍然得到同样的错误。
I still get the same error.
这个主题,它暗示你唱一些npm命令我还不熟悉(引用它):rm -rf node_modules和npm cache clean以及新的npm install。 我真的不明白所有这些内容是什么。
At some point in this thread , it suggests using some npm command I am not familiar with (yet), quoting it: "rm -rf node_modules and npm cache clean and a fresh npm install". I don't really understand what is under the hood of all this.
如果有人想出了神奇的解决方案,我将不胜感激使构建运行正常。但是我也想了解如何TypeError:无法读取未定义的属性'AssetUrl'可以与package.json链接?我不明白为什么这个错误会导致可能的解决方案。
I would be grateful if someone come up with the magic solution to make the build run fine. But also I'd like to understand how "TypeError: Cannot read property 'AssetUrl' of undefined" could be linked with the "package.json"? I don't get why this error lead to that possible solution.
我的版本是:
npm 3.10.3
节点6.7.0
cordova 6.3.1
离子2.1.0
My version are: npm 3.10.3 node 6.7.0 cordova 6.3.1 ionic 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:
Here is my package.json as it looks now afer operating the suggestion read in both threads:

我在项目文件夹中的CLI中执行了npm install+在package.json中删除依赖项和devDependencies前面的^符号(如在我的问题链接的论坛帖子中建议)。它解决了它。
I did in CLI within the folder of the projet an "npm install" + take away "^" sign in front of "dependencies" and "devDependencies" in package.json (as advised in the forum threads which are linked in my question). And it solved it.
