【问题描述】：

我无法使用 expo android 应用程序运行我的应用程序。我的设备在 Android Pie (8) 上运行。

世博安卓应用版本：2.11.10

我尝试在另一台设备上运行应用程序，但遇到同样的问题

error screen 27.0.0 不是有效的 SDK 版本。选项是 31.0.0、32.0.0、33.0.0 未版本化

我的 package.json 如下所示：

【解决方案1】：

您需要更新您的 expo 版本：

npm install（用于节点模块）
展会更新
npm install react-native-gesture-handler --save
npm 开始

我遇到了同样的问题，但是我运行了上面的命令并得到了输出

你可以在这里看到为什么会这样的解释：https://blog.expo.io/updated-expo-client-available-on-app-store-and-play-store-8747bd3a1364

【解决方案3】：

对我来说，解决方案是： “在您的 app.json 和 package.json 文件中，sdk 版本应该相同”

 "expo": {
"name": "ThirdReactApp",
"slug": "Third-React-App",
"privacy": "public",
"sdkVersion": "33.0.0",
"platforms": [
  "ios",
  "android"
],

  "dependencies": {
    "expo": "^34.0.1",
    "react": "16.8.3",
    "react-dom": "^16.8.6",
    "react-native": "https://github.com/expo/react-native/archive/sdk-33.0.0.tar.gz",
    "react-native-web": "^0.11.4"
  },

【解决方案4】：

您设备上的 Expo 客户端可能是最新的并且很好，但是您尝试加载的应用程序（项目）已经过时了。您只需将您的应用程序（项目）更新为更新且更兼容的 sdk。也就是说，请按照本网站上的说明获取有关如何执行此操作的分步指南。

【解决方案5】：

对于 27.0.0，您可以使用 Expo apk 2.10.6
