Expo没有找到“主要"在生产构建中的应用? [英] Expo does not find "main" application in production build?

问题描述

几周前我一直在尝试修复此错误，但没有成功.问题是我无法发布我的应用程序.

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.

当我为 iOS 或 Android 中的任何一个构建我的 expo 应用程序时，Expo CLI 签名过程运行良好，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，它会显示启动画面连续 4 或 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:

签出没有结果:

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} />;
}

我尝试过同样的结果:

• 将 "appKey": "main" 添加到 app.json 中
• 将 AppRegistry.registerComponent('main', () => App); 添加到 App.js 并展示 registerRootComponent(App) (分开并一起，这些都不起作用)
• 更改主"路径package.json 直接到 App.js 并使用上述方法注册应用程序手动

• 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

当我运行构建时，我也运行:

When I run build I also run:

exp start --no-dev --minify

所以我等待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，因此我无法发布我的应用程序.

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

推荐答案

原来我的 App 是一个函数，而我只是将函数本身传递给两个注册方法(react native 和 expo):

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 我缺少一个箭头函数:S

But in registerRootComponent I was missing an arrow function :S

registerRootComponent(()=>App())

:)
