世博会没有找到“主要”生产应用中的应用？ [英] Expo does not find "main" application in production build?

问题描述

从几周前开始，我一直在尝试纠正此错误，但没有成功。问题是因为这个原因，我无法发布我的应用。

I've been trying to fix this error from a couple weeks ago with no success. The problem is I cannot publish my app because of this.

当我同时为iOS或Android中的任何一个构建博览会应用时，Expo CLI签名过程进行得很好，没有错误并生成最终捆绑包，但是当我将spa或apk文件安装到真实设备中时，它会连续显示启动屏幕4到5次（某种循环），最后显示以下错误消息：

When I build my expo app for any of both, iOS or Android, the Expo CLI signing process goes well, no errors and generates final bundles but when I install the spa or apk file into a real device it shows the splash screen 4 or 5 times in a row (some kind of loop) and finally shows the following error messages:

我的package.json看起来像这样：

My package.json looks like this:

{
  "name": "Sxunco",
  "homepage": "https://www.sxunco.com",
  "version": "1.0.3",
  "private": true,
  "main": "node_modules/expo/AppEntry.js",
  "jest": {
    "preset": "jest-expo",
    "transformIgnorePatterns": [
      "node_modules/(?!((jest-)?react-native|react-clone-referenced-element|expo(nent)?|@expo(nent)?/.*|react-navigation|redux-persist|native-base(-shoutem-theme)|native-base|react-native-router-flux))"
    ]
  },....

我的App.js：

import React from 'react';
import Root from './src/native/index';
import configureStore from './src/store/index';

const { persistor, store } = configureStore();

export default function App() {
  return <Root store={store} persistor={persistor} />;
}

我尝试过相同的结果：

• 将 appKey： main 添加到app.json


• 添加 AppRegistry.registerComponent（'main'，（）=> App）; 进入App.js并同时博览会 registerRootComponent（App）（分开并一起使用，都不起作用）


• 将
  package.json中的主要路径直接更改为App.js，并使用上述方法$ b注册应用手动$ b

• Adding "appKey": "main" into app.json
• Adding AppRegistry.registerComponent(‘main’, () => App); into App.js and also expo registerRootComponent(App) (separated and both together, none of that works)
• Changing "main" path in package.json directly to App.js and register app with above methods manually

当我运行build时，我也运行：

When I run build I also run:

exp start --no-dev --minify

所以我等让服务器完成加载，然后运行 expo build：android

So I wait for the server to finish loading and then run expo build:android

请我不知道该怎么做，因此无法发布我的应用。

Please I don't know what to do, I cannot publish my app because of this.

推荐答案

结果是我的App是一个函数，而我只是在传递该函数本身对两种注册方法（反应本机和博览会）：

Turns out my App is a function, and I was just passing the function itself to both registration methods (react native & expo):

registerRootComponent（App（））

AppRegistry.registerComponent（appName，（）=> App（））;

但是在 registerRootComponent 中我缺少一个箭头函数： S

But in registerRootComponent I was missing an arrow function :S

registerRootComponent（（）=> App（））

：）
