Question

更新到 MacOS 10.15 Catalina 后， Flutter 出现了问题。

具体来说，Flutter医生抱怨以下方面：

下载的可执行文件无法在主机上执行。

未安装CocoaPods。

重要的是要解释一下，在更新之前，当我的计算机运行 Mojave 10.14 时，不存在Flutter的这些问题，因此flutter医生-v报告没有问题一切。

关于第一个问题：下载的可执行文件无法在主机上执行。

Flutter医生提供了以下链接：https://github.com/flutter/flutter/issues/6207

尽管如此，链接的文章指的是 Linux ，而不是 MacOS ...

关于第二个问题：未安装CocoaPods。

Flutter医生提出以下解决方案：

酿造可可豆

吊舱设置

尽管如此，尽管“ install cocoapods” 正常工作，但“ pod setup” 失败，指示以下错误：

/usr/local/bin/pod: /usr/local/Cellar/cocoapods/1.7.4/libexec/bin/pod: /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/pod: line 2: /usr/local/Cellar/cocoapods/1.7.4/libexec/bin/pod: Undefined error: 0

运行 flutter doctor -v 可获得以下结果：

请谦虚地请求您的帮助，以阐明当下载的可执行文件无法在主机上执行时是什么意思？

，该如何解决呢？请？

此外，如果使用Mojave 10.14时cocoapods运行良好，那么现在可能是什么问题，似乎无法成功运行 pod设置？

在升级到 MacOs 10.15 Catalina Beta之后，这里的其他人是否对Flutter产生了任何问题，而您在Mojave之前没有遇到过？

谢谢！！！

更新... 在研究此问题时，我遇到了一个非常悲伤的评论，这表明在Catalina中基本上不支持Flutter ...

请在这里找到它： https://github.com/flutter/flutter/issues/34000

评论说： 在MacOS 10.15上尚不支持Flutter ，尽管我们显然正在研究它。这是＃22598的重复，它与删除Catalina中的32位支持有关。

所以，我开始认为回到Mojave的安全可能是个好主意，至少Flutter工作得很好...

请分享您的想法，建议和建议？

Answer 1

可以安装cocoapods，运行flutter build ios并在iOS模拟器上运行。

brew uninstall cocoapods
sudo gem install -n /usr/local/bin cocoapods
pod install

详细说明在这里：This terminal won't let me run or install cocoa pods because I am on MacOS Catalina Beta?

Answer 2

对于此问题：

[！] Flutter（在Mac OS X 10.15 19A487m上为Channel dev，v1.7.11，语言环境 zh-CN）✗无法在主机上执行下载的可执行文件。看到 https://github.com/flutter/flutter/issues/6207了解更多信息

轻松修复：在MAC上打开终端并运行以下命令：

> flutter channel master

> flutter doctor

Answer 3

卸载并重新安装（如果您使用的是homebrew，则为）。

只需运行：

brew uninstall cocoapods && brew install cocoapods

MacOS 10.15 Catalina出现颤振问题
