更新到MacOS 10.15 Catalina后,Flutter存在问题。具体来说,Flutter doctor报告以下问题:
下载的可执行文件无法在主机上执行。
CocoaPods未安装。
需要说明的是,在更新之前,当我的电脑运行Mojave 10.14时,这些与Flutter有关的问题并不存在,因此flutter doctor -v报告没有任何问题。
关于第一个问题: 下载的可执行文件无法在主机上执行。 Flutter doctor提供了此链接:https://github.com/flutter/flutter/issues/6207。
然而,该链接所涉及的文章指的是Linux,而不是MacOS...
关于第二个问题:CocoaPods未安装。 Flutter doctor建议使用以下解决方案: brew install cocoapods pod setup 然而,尽管“install cocoapods”工作正常,但“pod setup”失败,指示以下错误:
运行flutter doctor -v命令,将返回以下结果:

恳请您帮忙解释一下,当显示“下载的可执行文件无法在主机上执行”时,这是什么意思?
还有,如何解决这个问题呢?请您帮帮忙!
此外,如果在使用Mojave 10.14时,Cocoapods正常运行,现在无法成功运行"pod setup",可能出了什么问题?
在升级到MacOS 10.15 Catalina Beta后,是否有其他人遇到 Flutter的任何问题,而之前在Mojave上没有?
非常感谢!!!
更新......
研究了这个问题后,我看到了一个非常令人难过的评论,它表明Catalina基本上不支持Flutter。
请查看以下链接: https://github.com/flutter/flutter/issues/34000
那个评论说: 尚未支持Flutter在macOS 10.15上运行,尽管我们正在关注它。这与#22598重复,涉及从Catalina中删除32位支持。
因此,我开始认为回到Mojave的安全状态可能是个好主意,至少Flutter工作得很好...
请分享您的想法、建议和意见?
