我正在尝试在M1 mac上构建flutter应用程序，并收到以下错误.

I'm trying to build a flutter app on M1 mac and getting the following error.

$ flutter build ios --release

推荐答案

我遇到了同样的问题.我运行 flutter build ios 时遇到了相同的错误.

I had the same issue. I saw the same error when I ran flutter build ios.

该错误消息在我的VS代码终端上显示为红色，但是有点误导.我发现这不是主要问题.

The error message was displayed red color on my VS code terminal, but it was kind of misleading. I found it was not the main issue.

实际问题应该在以下错误部分.

因此，请运行 flutter build ios --verbose 并仔细阅读输出.

So, please run flutter build ios --verbose and read the output carefully.

在我的情况下，还有 flutter build ios 失败的其他问题.问题就像忘记放入 GoogleService-Info.plist 一样，或者iOS目标版本小于flutter软件包的要求.

In my situation, there were other issues of the failure of flutter build ios. The issues were like forget to put in GoogleService-Info.plist or iOS target version is less than the requirement of flutter packages.
