【问题描述】：
我有一个要移植到 iphone 的 android 应用程序。几乎准备好了，在我的测试 iphone 上运行 30 多个编译，同时进行更改等。在提交到商店之前我需要运行的最后一次编译失败。
我为此花费了无数个小时，走上了许多不同的道路。从锁定文件夹中的损坏文件开始，通过不再有证书钥匙串条目移动，现在终于到了一个我什至不再知道出了什么问题的地方，所以我迫切需要一些帮助。
这是我的颤振医生的输出：

You may also want to add it to your PATH environment variable.

这就是我现在从 flutter run -v 得到的：
TL;DR 部分可能在这里？这也是我尝试从 Xcode 启动时遇到的相同错误，但正如我所说，我之前能够多次运行此应用程序，但我没有添加任何内容：

更大的输出在这里，但由于字符限制，我无法包括所有输出：
