flutter - 在 `cloud_firestore` 中找不到 `.symlinks/plugins/cloud_firestore/ios` 的 podspec

Question

在我的 pubspec.yaml 文件中添加 cloud_firestore 依赖项后，我遇到了这个问题。

这是控制台中的完整消息:

如果我删除 cloud_firestore 依赖项，该应用程序会正常运行。

将 Firestore 添加到我的项目时，我开始执行 Firebase 控制台中的所有步骤，因此我还执行了第 3 步:pod init、pod 'Firebase/Core'、pod install。 然后通过在线搜索其他资源，我了解到我不应该这样做。 这可能是原因吗？

更新 根据要求，这是我的 pubspec.yaml。很简单

    sdk: flutter
  rxdart: 0.18.1
  rx_command: 2.0.5
  flutter_localizations:

  cloud_firestore: 0.8.2+3
  device_id: 0.1.3

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.

dev_dependencies:

我尝试了您的 pubspec.yaml 文件，从支持 Swift 的 Flutter 应用程序开始。

name: flutter_app_so_53935700
description: A new Flutter application.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# Read more about versioning at semver.org.
version: 1.0.0+1

environment:
  sdk: ">=2.0.0-dev.68.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  rxdart: 0.18.1
  rx_command: 2.0.5
  flutter_localizations:
    sdk: flutter
  cloud_firestore: 0.8.2+3
  device_id: 0.1.3

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  built_value: "6.1.2"
  built_collection: "4.0.0"

dev_dependencies:
  flutter_test:
    sdk: flutter
  build_runner: 0.10.2
  built_value_generator: 6.1.2
  flutter_launcher_icons: "0.6.1"


# For information on the generic Dart part of this file, see the
# following page: https://www.dartlang.org/tools/pub/pubspec

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  # assets:
  #  - images/a_dot_burr.jpeg
  #  - images/a_dot_ham.jpeg

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.io/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
  #
  # For details regarding fonts from package dependencies,
  # see https://flutter.io/custom-fonts/#from-packages

一切都很好。

Launching lib/main.dart on iPhone XR in debug mode...
Running pod install...
Starting Xcode build...
Xcode build done.                                           122.0s

使用有效的 .ios/Runner/GoogleService-Info.plist 我最终得到了一个正在运行的 flutter 演示应用程序。

再次阅读你的问题，特别是

step 3: pod init, pod 'Firebase/Core', pod install

看来您还更改了 .ios/Podfile 文件，手动添加 pod 'Firebase/Core'。您不必那样做。

您可以在这里找到正确的说明:

您必须停止广告第 2 步。无论如何请尝试此codelab Firebase for Flutter它将指导您完成在 Flutter 应用程序中添加 Cloud Firestore 的过程。
