// No problem at all with this code
import {View, Text} from 'react-native'
const App = () => {
    return (
        <View>
            <Text>
                Test
            </Text>
        </View>
    )
}

export default App

OUTPUT: LOG  Running "Chat" with {"rootTag":161,"initialProps":{}}
info Reloading app...
 BUNDLE  ./index.js 

********************************************

// but as soon as I import

import {View, Text} from 'react-native'
import {Voximplant} from 'react-native-voximplant';  <--

const client = Voximplant.getInstance();   <--

const App = () => {
    
    return (
        <View>
            <Text>
                Test
            </Text>
        </View>
    )
}

export default App

// I get the following.
OUTPUT: LOG  Running "Chat" with {"rootTag":171,"initialProps":{}}
 ERROR  Invariant Violation: `new NativeEventEmitter()` requires a non-null argument., js engine: hermes

我已经尝试了GitHub上所有最新的答案和堆栈溢出,但没有一个工作。在这一点上,我不知道该怎么办。做这个问题,我无法使用Voximplant。

只是为了确认一下,在添加新模块后,你是否在ios文件夹中运行了pod install
当你安装了一个新模块,但没有为iOS开发生成pod时,这看起来像是一个错误。
步骤:
1.导航到react-native项目中的ios文件夹。
1.从终端运行pod install
1.在Xcode上,使用快捷方式cmd+shift+k清理项目。(专业提示:您可以删除~/Library/Developer/XCode/DerivedData中的DerivedData文件夹,它将在您成功构建应用程序后重新生成)。
1.构建您的应用程序(cmd+r);
