reactjs - 31.0.0 不是有效的 SDK 版本。选项为 32.0.0 UNVERSIONED

Question

我无法在模拟器和设备上运行我的应用程序。之前它可以正常工作。

我已尝试过此博客中提到的每一步

Official Blog for updation

我的package.json是

{
"main": "node_modules/expo/AppEntry.js",
  "scripts": {
"android-windows": "react-native bundle --platform android --dev false --entry-file App.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res && react-native run-android",
"start": "expo start",
"android": "expo start --android",
"ios": "expo start --ios",
"eject": "expo eject",
"debugWindow": "start 'rndebugger://set-debugger-loc?host=localhost&port=8081'",
"debugLinux": "open 'rndebugger://set-debugger-loc?host=localhost&port=8081'"
 },

"dependencies": {
    "expo": "^31.0.4",
    "react": "16.5.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-31.0.1.tar.gz",
    "react-navigation": "^3.0.8"
  },
  "devDependencies": {
    "babel-preset-expo": "^5.0.0"
  },
  "private": true
}

并且 App.json 是

{


 "expo": {
    "name": "AwesomeProject",
    "slug": "AwesomeProject",
    "privacy": "public",
    "sdkVersion": "31.0.0",
    "platforms": [
      "ios",
      "android"
    ],
    "version": "1.0.0",
    "orientation": "portrait",
    "icon": "./assets/icon.png",
    "splash": {
      "image": "./assets/splash.png",
      "resizeMode": "contain",
      "backgroundColor": "#ffffff"
    },
    "updates": {
      "fallbackToCacheTimeout": 0
    },
    "assetBundlePatterns": [
      "**/*"
    ],
    "ios": {
      "supportsTablet": true
    }
  }
}

我尝试运行 npm install 2-3 次，但似乎没有任何效果。

我不明白为什么它建议使用选项 32.0.0，而此链接上没有此选项的发行说明。 Upgrading Expo

这是一个已知问题 https://github.com/expo/expo/issues/3112

这是由于 Play 商店中的 Expo 应用程序存在错误。如果您使用的是 v2.10.0，那么您应该升级到 v2.10.1

Sorry guys for the trouble 😞 We've fixed this issue in v2.10.1 that was released just a few hours later so you should already have an update.
