node.js - 未处理的 promise 拒绝警告 : Error: Cannot find module '/MyProject/node_modules/react-native-scripts/build/scripts/init.js'

Question

我正在尝试使用 Facebook React Native 教程构建一个新的 React Native 项目。这个命令以前对我有用，但现在我突然收到这个错误消息。

(node:14866) UnhandledPromiseRejectionWarning: Error: Cannot find module '/MyProject/node_modules/react-native-scripts/build/scripts/init.js'

我不确定发生了什么变化，但我找不到解决方法。谁能帮忙？

编辑:启动 React Native 应用程序的新方法可在此处找到:https://github.com/react-community/create-react-native-app

答案如下。

Answer 1

Create React Native App 已更改，现在使用新的 Expo CLI。

我按照此处的说明操作:https://github.com/react-community/create-react-native-app

$ npm install -g expo-cli
$ expo init AwesomeProject
$ cd AwesomeProject
$ expo start

它现在将打开一个新的本地主机 Metro Bundler，它有一个 GUI，允许您运行模拟器、发送链接或发布您的项目。
