无法解析模块ReactNativeEventEmitter

Question

After upgrading React Native from 0.29 to 0.30, I get this error message. I multiple times deleted node_modules, installed them back again, cleared watchman cache and npm start --reset-cache.

I tried it also on new project with react-native init someProject. The same error. Was this module renamed or deleted? I haven't found any info about it in release notes or in commits.

Thanks for help!

Answer 1

It's no longer needed. onTouchStart, onTouchEnd and onTouchMove are props of Views now. Look here

Answer 2

I don't know, what really happened to this component.

But, at least, currently on RN 0.30 you can require ReactNativeEventEmitter as follows:

var ReactNativeEventEmitter=require(127);

The following line ...

console.log(ReactNativeEventEmitter)

...will print then this in the console (in Debug-Mode):

(I've figured it out while searching the react-native libraries in "node-modules" in the following file: "./node_modules/react-native/ReactAndroid/src/androidTest/assets/AndroidTestBundle.js:13879", and it is also working under iOS [the screenshot above originates from iOS]).

您是否尝试使用以下代码段导入？

import { DeviceEventEmitter } from 'react-native';
