我有同样的问题。

帮助我调整了世博会的版本和版本。

它是:

package.json

"dependencies": {
  "expo": "^30.0.1",
  "react-native": "https://github.com/expo/react-native/archive/sdk-29.0.0.tar.
}

app.json

"expo": {
  "sdkVersion": "29.0.0",
}

它变成了:

package.json

"dependencies": {
  "expo": "^30.0.1",
  "react-native": "https://github.com/expo/react-native/archive/sdk-30.0.0.tar.
}

app.json

"expo": {
  "sdkVersion": "30.0.0",
}
