我已经将一个分离的 Expo 项目升级到 Expo SDK 29。现在我想运行 pod install，但是当我这样做时，我收到以下错误消息:

[!] CocoaPods could not find compatible versions for pod "EXPermissionsInterface":
  In Podfile:
    EXCamera (from `../node_modules/expo-camera/ios`) was resolved to 1.0.1, which depends on
      EXPermissionsInterface

    EXPermissionsInterface (from `../node_modules/expo-permissions-interface/ios`)

Specs satisfying the `EXPermissionsInterface (from `../node_modules/expo-permissions-interface/ios`), EXPermissionsInterface` dependency were found, but they required a higher minimum deployment target.

很遗憾，我还没有在网络上发现这个错误。我的 Podfile 看起来像这样:

  end
end

为了创建 Podfile，我按照 Expo 在 Github 上提供的说明进行操作。

我认为解决我的问题并不重要，但是，这是我的 package.json:

{
  "main": "node_modules/expo/AppEntry.js",
  "private": true,
  "dependencies": {
    "@expo/react-native-action-sheet": "^1.1.2",
    "@mapbox/polyline": "^1.0.0",
    "expo": "^29.0.0",
    "i18next": "^11.9.0",
    "i18next-locize-backend": "^1.6.0",
    "locize-editor": "^1.6.0",
    "native-base": "^2.7.2",
    "prop-types": "^15.6.2",
    "react": "16.3.1",
    "react-i18next": "^7.12.0",
    "react-native": "https://github.com/expo/react-native/archive/sdk-29.0.0.tar.gz",
    "react-native-create-bridge": "^2.0.1",
    "react-native-keyboard-spacer": "^0.4.1",
    "react-native-maps": "^0.21.0",

    "redux-thunk": "^2.3.0"
  }
}

最佳答案

我也在 Github 上问过这个问题并在那里得到了有效的答案:https://github.com/expo/expo/issues/2585 .

问题是我在 Podfile 中定义的最低 iOS 版本。将此版本从 9.0 更改为 10.0 后，我可以毫无问题地运行 pod update。

关于ios - 博览会套件 : 'pod update' error after updating to SDK 29，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53143437/
