angular - 汇总 - 命名空间冲突

Question

我目前正在构建 Ionic 2-RC3 应用程序。但是自从我升级到 RC-1 后，我遇到了以下错误:(不确定它们是否保持不变，但你明白了)。

现在我的问题是，是哪条线路造成了这种情况，为什么会发生这种情况？因为对我来说，我的 package.json 中似乎没有重复值。

rm -rf node_modules && npm install 没有解决这个问题。

Answer 1

可能是 rollup.config.js 的问题

Default ionic rollup config

另请查看 Third party module exports here .

你可以:

Open node_modules/@ionic/app-scripts/config/rollup.config.js and copy and paste the file content into scripts/rollup.config.js.

然后从那里开始，但如果您有自定义设置，则需要一些返工。希望对您有所帮助。
