How to resolve Uncaught Error:29.0.0 in React Native Expo project

问题

I am trying out a demo of a react-native application that was built (not by me) using Expo approach. After installing dependencies and trying to run the application; I get the error below:

Uncaught Error: 29.0.0 is not a valid SDK version. Options are 35.0.0 , 33.0.0, UNVERSIONED. 16:56:55 Fatal Error.

Here is the package.json file:

{
  "name": "food-shop",
  "main": "node_modules/expo/AppEntry.js",
  "private": true,
  "scripts": {
    "start": "expo start",
    "android": "expo start --android",
    "ios": "expo start --ios",
    "eject": "expo eject"
  },
  "dependencies": {
    "expo": "^29.0.0",
    "expokit": "^1.5.0",
    "react": "16.3.1",
    "react-native": "https://github.com/expo/react-native/archive/sdk-29.0.0.tar.gz",
    "react-navigation": "^2.11.2"
  }
}

I am using Huawei Y5 Lite, Android 8.1.0. What I wish to know is,how can I resolve this error?

Thanks.

The current version of the Expo app only supports SDK 33+

We routinely drop SDK versions that have low usage, but we’ve dropped more versions than usual with this release. SDK 33 was the first version that included 64-bit support, and in order for us to update the Expo client on Google Play, every SDK version we include must have 64-bit support. This release sees the end of life for SDKs 31 and 32. As usual, your standalone apps built with these SDK versions will continue to work; however, SDK 31 and 32 projects will no longer work within the latest version of Expo Client. At this time, you can still run expo build for SDK 31 and 32 projects. Note, however, that you must upgrade to 33 or later in order to submit an updated APK to Google Play due to the 64-bit requirement. We will remove support for SDKs 31 and 32 in expo build in a future release. If you still need to test a project running SDK 31 or 32, you can download this Android client version and this iOS client version.

You won’t be able to run that app unless you update the sdk to a more recent one.
