Flutter 为什么颤振桌面嵌入会在构建时抛出错误？

我想在windows上运行我现有的颤振应用程序，所以我加载了最新的颤振桌面嵌入版本，将代码放入其中并尝试运行它。它很快就会崩溃，只有一个例外：

Build process failed. To view the stack trace, please run `flutter run -d windows -v`.

我正在主频道上开发，已经进行了颤振升级，否则我想我已经做了我需要做的一切。使用Flatter desktop embedding运行示例comming不会引发任何异常，而且如果我将lib文件夹复制到examples文件夹中，应用程序将不会生成

有人也面临这个问题吗？

这个问题是由颤振版本解决的

打开终端并写入

flatter升级--force

打开Windows Flatter项目并编写

Flatter run

正如错误消息所说，您当前需要以详细模式进行构建，以获得必要的输出，从而了解底层本机构建失败的原因。那里的

flatter

工具堆栈跟踪只表明本机构建失败；该步骤中的任何失败都将具有相同的堆栈。您忘了提到这是详细输出它肯定不是整个详细输出，因为在您所展示的内容中，本机构建步骤中绝对没有输出。如果输出中没有指示生成中失败的部分，则无法调试问题。
