MacOS 10.15 Catalina 的 Flutter 问题

Question

更新到 后MacOS 10.15 Catalina ，有问题 flutter .

具体来说，Flutter 医生提示以下几点:

下载的可执行文件无法在主机上执行。

未安装 CocoaPods。

需要说明的是，在更新之前，当我的计算机运行 Mojave 10.14 时，Flutter 不存在这些问题，因此 flutter doctor -v 没有报告任何问题。

关于第一期:下载的可执行文件无法在主机上执行。

Flutter 医生提供此链接:https://github.com/flutter/flutter/issues/6207

然而，链接的文章指的是 Linux，而不是 MacOS...

关于第二期:未安装 CocoaPods。

Flutter 医生建议如下解决方案:

brew 安装 cocoapods

pods 设置

尽管如此，虽然“安装 cocoapods”工作正常，但“pod setup”失败，提示以下错误:

/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 医生 -v 提供以下结果:

我虚心地请求您的帮助，请澄清 的含义。下载的可执行文件无法在主机 上执行?

并且，可以做些什么来解决它？ 请？

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

这里还有其他人吗 Flutter 的任何问题 升级到 后MacOs 10.15 Catalina Beta，您之前在 Mojave 中没有？

谢谢你 !!!

更新...
研究这个问题，遇到了一个很伤心的评论，说Catalina基本不支持Flutter...

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

评论说:
macOS 10.15 尚不支持 Flutter ，虽然我们显然正在研究它。这是#22598 的副本，它与从 Catalina 中删除 32 位支持有关。

所以，我开始认为回到 Mojave 的安全地带可能是个好主意，至少 Flutter 工作正常......

请分享您的想法，建议，意见？

Answer 1

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

brew uninstall cocoapods

sudo gem install -n /usr/local/bin cocoapods

pod install
