在 flutter 中运行 Xcode 构建需要很长时间

Question

    My flutter doctor summary:\n    \n    Doctor summary (to see all details, run flutter doctor -v):\n    [\xe2\x9c\x93] Flutter (Channel stable, 2.8.1, on macOS 12.1 21C52 darwin-x64, locale en-IN)\n    [\xe2\x9c\x93] Android toolchain - develop for Android devices (Android SDK version 32.0.0)\n    [\xe2\x9c\x93] Xcode - develop for iOS and macOS (Xcode 13.2.1)\n    [\xe2\x9c\x93] Chrome - develop for the web\n    [\xe2\x9c\x93] Android Studio (version 2020.3)\n    [\xe2\x9c\x93] VS Code (version 1.63.2)\n    [\xe2\x9c\x93] Connected device (2 available)\n    \n    \xe2\x80\xa2 No issues found!\n\nMy flutter doctor shows no issues. Can someone help me out with this? I tried flutter clean & other stuff & did not help. But app gets opened in the simulator if i create a new project but once i add dependencies it does not build.\n\n\nUpdate:\nWhen i run flutter run -v log i get this as error:\n\n[  +47 ms] Target file "log" not found.\n[   +3 ms] \n           #0      FlutterCommand.validateCommand\n(package:flutter_tools/src/runner/flutter_command.dart:1420:9)\n           #1      RunCommand.validateCommand (package:flutter_tools/src/commands/run.dart:460:19)\n           #2      FlutterCommand.verifyThenRunCommand\n           (package:flutter_tools/src/runner/flutter_command.dart:1248:11)\n           <asynchronous suspension>\n           #3      FlutterCommand.run.<anonymous closure>\n           (package:flutter_tools/src/runner/flutter_command.dart:1140:27)\n           <asynchronous suspension>\n           #4      AppContext.run.<anonymous closure>\n(package:flutter_tools/src/base/context.dart:150:19)\n           <asynchronous suspension>\n           #5      CommandRunner.runCommand (package:args/command_runner.dart:209:13)\n           <asynchronous suspension>\n           #6      FlutterCommandRunner.runCommand.<anonymous closure>\n           (package:flutter_tools/src/runner/flutter_command_runner.dart:288:9)\n           <asynchronous suspension>\n           #7      AppContext.run.<anonymous closure>\n(package:flutter_tools/src/base/context.dart:150:19)\n           <asynchronous suspension>\n           #8      FlutterCommandRunner.runCommand\n           (package:flutter_tools/src/runner/flutter_command_runner.dart:236:5)\n           <asynchronous suspension>\n           #9      run.<anonymous closure>.<anonymous closure> (package:flutter_tools/runner.dart:62:9)\n           <asynchronous suspension>\n           #10     AppContext.run.<anonymous closure>\n(package:flutter_tools/src/base/context.dart:150:19)\n           <asynchronous suspension>\n           #11     main (package:flutter_tools/executable.dart:94:3)\n           <asynchronous suspension>\n           \n           \n[ +274 ms] ensureAnalyticsSent: 266ms\n[   +1 ms] Running shutdown hooks\n[        ] Shutdown hooks complete\n[        ] exiting with code 1\n

这是我运行 flutter run -v log 时最后得到的结果。\n我不明白在这里要做什么。有人可以帮我解决这个问题吗？

几个小时以来我一直被困在这一点上。当我在我的真实 Android 设备上运行我的应用程序时，它会在几分钟内构建完成，但是当我在 ios 模拟器上运行它时，它会持续加载“运行 Xcode 构建”几个小时并且没有给出任何结果。我的 Android 模拟器上也出现同样的问题，它卡在“正在运行 Gradle 任务 'assembleDebug'...”

我之前也遇到过同样的问题，但只是在 iOS 模拟器中，我找到了 0 个解决方案。我使用 VS code，android 运行完美，但如果我在模拟器上运行它，则需要很长的时间。我通过这些步骤解决了这个问题。

首先，扑干净。

从终端，通过此命令转到 iOS 文件夹>> cd ios。

吊舱安装

如果 pod install 卡在 IDE 终端中，则转到项目查找器位置并进入 ios 文件夹并打开终端并运行 pod install。

我用这种方法解决了我的问题。
