【问题描述】：

当我在 iOS 模拟器上为 iOS 构建 Flutter 项目时，它给了我一个错误

ld: framework not found Flutter

构建失败。

这是我尝试从 xcode 构建颤振项目时的错误消息：

【解决方案1】：

只需要删除flutter文件夹，然后你可以把flutter文件夹放到同一个路径，解压最新的flutter zip，重启系统，就可以了..

【讨论】：

    【解决方案2】：

    我已经尝试了很多解决此错误的方法。 唯一可能的解决方案是删除 FLUTTER PATH 中的flutter文件夹，然后重新复制flutter文件夹。

    这解决了我的错误。

    【讨论】：

    • 谢谢伙计。我一直在做：清理这个，删除这个，已经 3 天了。 Flutter clean，flutter upgrade，pod install，pod disintegrate，clean build folder，删除一些路径。他们都没有工作。这是唯一的解决方案！干杯。
    • 从哪里复制？
    • @Mikki 你可以重新复制到相同的路径，感谢 Anivesh Readdy 的工作原理
    • 唯一有效的解决方案，遗憾的是这个错误还没有修复！
    • FLUTTER PATH ，是 sdk 路径 .... 只需下载新的 sdk 并用新下载的 sdk(flutter) 替换旧的 sdk 文件夹 (flutter)。
    【解决方案3】：

    错误原因是我从 Documents 文件夹中删除了颤振命令行。但它通过运行flutter upgrade 解决了

    【讨论】：

    • 就我而言，它有帮助。
    【解决方案4】：

    这对我有用。

    删除项目中的ios 文件夹，然后再次运行。

    【讨论】：

      【解决方案5】：

      您缺少 Flutter 以将其添加到其 PATH

      导航到flutter包，获取文件夹路径并将其添加到应该看起来像的路径中。

      export PATH=$PATH:/package_to_flutter/bin

      此外，格式化您的问题，以便人们更容易快速回答。

      干杯

      【讨论】：

      • 我成功为android编译和构建。但是当我要为 ios 编译和构建时，会显示错误“找不到 Flutter 框架”。所以这可能不是路径问题。请看一下。命令“echo $PATH”的输出：- /Library/Frameworks/Python.framework/Versions/3.6/bin:/Library/Frameworks/Python.framework/Versions/3.6/bin:/usr/local/bin:/usr/ bin:/bin:/usr/sbin:/sbin:/Users/abhijeetnigoskar/android-sdks/platform-tools/:/Users/abhijeetnigoskar/android-sdks/tools/:/Users/abhijeetnigoskar/flutter/bin
      • 似乎是某种类型的颤振依赖问题。尝试运行flutter channel master，然后运行flutter upgrade，然后尝试重新运行构建。
      【解决方案6】：

      尝试从您的项目中删除 CocoaPod

      cd ios
pod deintegrate
flutter clean
flutter run

      如果这不起作用，请尝试重新安装 Flutter

      【讨论】：

        【解决方案7】：

        不安装整个包即可解决问题

        我错误地从框架目录中删除了Flutter.runner 文件。它在构建版本时开始显示此错误。然后我做了以下步骤而不是安装所有包

        1. 删除了myproject/ios/Flutter/Flutter.framework 文件夹
        2. 在iOS目录下运行pod install（你可以试试，删除所有pod配置重新安装）

        可能会发生什么？对于一些开发人员来说，他们正在重新安装颤振包，然后问题就消失了，基本上在我的情况下，我想通过丢失项目的flutter.runner 文件来补充一点，你正在删除你的颤振应用程序的 iOS 配置。 Flutter 命令不起作用，因此解决方案有效。

        【讨论】：

          【解决方案8】：

          我亲自尝试了我在论坛上看到的所有内容，但对我有用的是删除 Flutter SDK 并重新下载然后运行。它对我有用，其他东西可能对你有用。 问题基本上是两天前该项目运行良好，然后可能发生了一些我可能做过的颤振升级降级等事情，这似乎是导致这个问题的原因。但总的来说

          总结：删除flutter SDK并为我下载新的工作

          【讨论】：

            【解决方案9】：

            删除flutter SDK文件夹并重新下载

            flutter upgrade
flutter pub get
pod install

            【讨论】：

              【解决方案10】：

              在我的情况下，我在尝试清理我的 258go macbook 上的一些存储以更新 Xcode 时删除颤振实例后收到此错误 :(，这样做我可能删除了颤振框架。

              这里给出的解决方案对我来说没有任何改变。

              所以我尝试清理 pod 中的所有内容，包括缓存。 pod install命令失败，因为它错过了ios工具，可以用flutter precache --ios下载。

              所以为我解决这个问题的完整过程是：

              cd ios
pod cache clean --all
rm -rf ~/Library/Caches/CocoaPods
rm -rf Pods
rm -rf ~/Library/Developer/Xcode/DerivedData/*
pod deintegrate
flutter precache --ios
pod install

              我希望这个解决方案能帮助某人，防止他们像我一样失去一整天的工作。
