ios - Flutter 应用程序未在 ios 上运行（来自 CocoaPods 的错误输出）

问题描述

我的颤振应用程序没有在 ios 模拟器上运行，这就是它所说的：

   [!] Automatically assigning platform `iOS` with version `9.0` on target
    `Runner` because no platform was specified. Please specify a platform for
    this target in your Podfile. See
    `https://guides.cocoapods.org/syntax/podfile.html#platform`.

Error running pod install
Error launching application on iPhone 12 Pro Max.

当我运行颤振医生时，它显示了这一点：

[✓] Flutter (Channel stable, 2.0.3, on macOS 11.2 20D64 darwin-arm, locale en)
[✓] Android toolchain - develop for Android devices (Android SDK version 30.0.3)
[✓] Xcode - develop for iOS and macOS
[✓] Chrome - develop for the web
[✓] Android Studio (version 4.1)
[✓] VS Code (version 1.54.3)
[✓] Connected device (2 available)

此外，当我对此发表评论时，platform :ios, '9.0'它向我展示了这一点：

    [!] CocoaPods could not find compatible versions for pod "cloud_firestore":
      In Podfile:
        cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`)

    Specs satisfying the `cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`)` dependency were found, but they required a higher minimum
    deployment target.

请有人帮忙解决这个问题，这个问题已经有一段时间了。

解决方案

检查 iOS 文件夹中的 Podfile 并将全局版本设置为 9.0

取消注释此行以为您的项目定义一个全球平台

平台：ios，'9.0'
