Question

启动命令npm run eject后，我按照以下步骤操作：

光秃秃的：我想要一个裸露的React Native项目。
我设置了应用程序和xcode项目的名称

命令返回此消息Ejected successfully! 之后，在ios生成的文件夹中，运行命令pod install，结果为Pod installation complete!

执行此过程后，我尝试使用ios模拟器运行应用程序，但出现此错误：

Expo SDK需要运行Expo。似乎本地Expo模块不可用，并且此代码未在Expo上运行。访问https://docs.expo.io，以了解有关开发世博项目的更多信息。

请注意，在执行npm run eject命令之前，应用程序正常运行。

这是package.json之前的eject：

{
  "main": "node_modules/expo/AppEntry.js",
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "web": "expo start --web",
    "eject": "expo eject"
  },
  "dependencies": {
    "@apollo/react-hooks": "^3.0.1",
    "apollo-boost": "^0.4.4",

  },
  "devDependencies": {
    "babel-preset-expo": "^6.0.0"
  },

}

在eject之后，package.json变为：

您遇到的问题是，您在App.js中有一个来自“ expo”包的AppLoading，如果没有expExpSDK，就不会提供支持。您必须删除该字体并将字体放在componentDidMount（）

中

使用expo退出应用程序后出现问题
