【问题描述】:
我刚刚设置了一个应用程序以开始构建它,并且我不断从我的 App.js 中收到此错误。这是 udemy 课程的一部分,在该课程中,我遵循了 T 的每条指令......所以我对到底发生了什么感到非常困惑,并且我遵循了我能找到的每一个建议。 Unable to resolve module react-navigation from /Users/3x7r3m157/Development/React-Native/food/App.js: Module react-navigation does not exist in the Haste module map.
This might be related to https://github.com/facebook/react-native/issues/4968
To resolve try the following:
1. Clear watchman watches: `watchman watch-del-all`.
2. Delete the `node_modules` folder: `rm -rf node_modules && npm install`.
3. Reset Metro Bundler cache: `rm -rf /tmp/metro-bundler-cache-*` or `npm start -- --reset-cache`.
4. Remove haste cache: `rm -rf /tmp/haste-map-react-native-packager-*`.

这是我的 App.js:
import { createAppContainer } from 'react-navigation';
import { createStackNavigator } from 'react-navigation-stack';
import SearchScreen from './src/screens/SearchScreen';
const navigator = createStackNavigator ({
Search: SearchScreen
}, {
initialRouteName: 'Search',
defaultNavigationOptions: {
title: 'BusinessSearch'
}
});
export default createAppContainer(navigator);
【问题讨论】:
-
你安装了 react-navigation 吗?你应该将你的 package.json 添加到这个问题中,因为错误似乎与它有关
-
就是这样。细节中的魔鬼......谢谢!
