Flutter 颤振iOS模拟继续生成失败的Xcode

刚刚安装了颤振，但颤振一直未能在iOS模拟器中打开新的项目

终端错误

我试过用颤振清洁，但不起作用

我跑去看医生，但一切似乎都很好

请帮忙

更新日期：8月1日 跑了颤振跑-v，这是结果。但我还是无法从Flatter run启动文件。但是，Xcode可以很好地构建和运行该文件。Android Studio也是如此

有人知道发生了什么事吗？

没关系。我不明白为什么。擦掉我的硬盘，重新安装macOS Catalina和Xcode，现在它可以正常工作了。

Nevermind。我不明白为什么。擦掉我的硬盘，重新安装macOS Catalina和Xcode，现在它可以工作了。

所以我用Xcode运行了颤振代码的iOS部分，它确实在模拟器上运行了！（新创建的颤振应用程序）。然而，我仍然无法让它在终端上用flifter运行，不知道为什么。所以我用Xcode运行了flifter代码的iOS部分，它确实在模拟器上运行了！（新创建的颤振应用程序）。然而，我仍然无法让它在终端上运行，不知道为什么。
