当尝试运行 React native iOS 应用程序时,我收到一个错误的红色页面。这是我在 iOS 屏幕上遇到的以下错误。
Failed to load bundle(http://localhost:8081/index.bundle?platform=ios&dev=true&minify=false) with error:(Unable to resolve module ./node_modules/react-native/src/constants/screens from/Users/username/Desktop/mobile/App.js: The module ./node_modules/react-native/src/constants/screens could not be found from /Users/username/Desktop/mobile/App.js. Indeed, none of these files exist:

我尝试通过查看其他 stackoverflow 帖子来解决这个问题。但是,到目前为止,没有一种解决方案对我有用。老实说,我很困惑,不知道该怎么办。感谢您提供任何帮助或建议。
最佳答案
快速修复:npm 添加@babel/runtime
然后:rm -rf ios/build/;杀死 $(lsof -t -i:8081); react native 运行 ios
