Question

我正在通过编写一个非常简单的聊天应用程序来学习本机（0.58.5）。 Chat.js下有一个模块components。但是错误不断要求在Main.js下缺少名为components的模块。在启动“ react-native run-android Main.js Main.js . And the error is the same even if I put the components”之前，模块back under已删除。这是错误：

这里是App.js：

import React, { Component } from "react";
import Chat from "./components/Chat";

export default class App extends Component {
  render() {
    return <Chat />;
  }
}

以上完全没有引用Main.js。是Main.js中的React Native保留模块吗？

Answer 1

搜索index.android.bundle并从您的android文件夹中删除。

杀死地铁捆绑器的所有实例。

在项目的android文件夹的cmd或powershell中运行gradlew clean

点击react-native run-android

为什么反应本机应用程序不断询问被删除的main.js？
