ios - ExpoKit : 'pod update' error after updating to SDK 29

我已经将一个独立的 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:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'

要创建 Podfile，我已按照 Expo 在 Github 上提供的相应说明进行操作。

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",

    "locize-editor": "^1.6.0",
    "native-base": "^2.7.2",

我也在 Github 上问过这个问题，并在那里得到了一个有效的答案: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。
