在 flutter 运行期间出现错误。 错误有一些 pod 文件。 有谁知道如何解决？

Question

我做了 pod repo 更新。 它不工作。 我在 Mac 上运行。 我尝试重新安装 cocapods，但它也没有帮助。 我该如何解决这个问题？ 现在真的被困了一天。 这是它给出的错误：

错误：CocoaPods 的规范存储库太旧，无法满足依赖关系。 要更新 CocoaPods 规范，请运行： pod repo update

[!] CocoaPods could not find compatible versions for pod "Firebase/CoreOnly":
  In snapshot (Podfile.lock):
    Firebase/CoreOnly (= 8.7.0)

  In Podfile:
    firebase_core (from `.symlinks/plugins/firebase_core/ios`) was resolved to 1.10.6, which depends on
      Firebase/CoreOnly (= 8.9.0)


You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `Firebase/CoreOnly` inside your development pod `firebase_core`.
   You should run `pod update Firebase/CoreOnly` to apply changes you've made.

好吧，基本上你的 CocoaPods 设置会坏掉。 您将不得不手动删除 Specs 存储库的任何本地副本并重新克隆 Specs 存储库的新版本。 您可以使用以下命令执行此操作：

经过大量解决方案应用后，我找到了一种成功解决此错误的方法，如下所示

可以通过在终端执行以下命令来解决。

Go 到项目内的 /ios 文件夹。 删除英特尔芯片用户的 Podfile.lock (YourPoject/ios/Podfile.lock)

运行 pod install --repo-update （确保您的 cd 进入 flutter 应用程序的 iOS 目录）对于 M1 芯片用户

首先安装 ffi（如果没有）在常规终端中使用命令： sudo arch -x86_64 gem install ffi 然后 arch -x86_64 pod install --repo-update

运行 flutter 清洁

完成后，重新构建您的 Flutter 应用程序： flutter 运行
