您好，我将 Flex 3 项目迁移到 Flex 4：我收到以下错误：

任何人都有关于在 Flex 4 中解决此问题的想法。

感谢您的帮助。

【问题讨论】：

你最好列出编译器错误突出显示的行。
@Constantiner 通常像这样的错误没有行号，并且与库和主项目之间的版本不匹配有关。（见我的回答）。如果您因缺乏细节而对 b/c 投了反对票，我建议您删除您的反对票，因为老实说，我相信原始海报没有更多额外的细节可提供。
@www.Flextras.com 不，我没有投反对票，我认为这些错误没有特定的行，但我认为如果主题启动者指出这一事实会更好:)
@Constantiner 我讨厌人们投票反对而没有说明原因。 ;)

【解决方案1】：

此类错误通常是由于版本不匹配问题造成的。因此，请确保您的所有外部库都使用与您的主项目相同的 Flex SDK 版本进行编译。

如果您使用的是框架，或者您在网络上找到的其他库，如果源代码可用，您可能必须自己重新编译它们。

【讨论】：

您好，其实在flex 3项目中有一个类叫PopUpManagerImpl.as。正是从这个文件中得到了所有这些错误。如果可能的话，请对此有所了解。谢谢
@FlexyBoz 除了我已经说过的话，我不知道还能告诉你什么。这个问题通常与特定的类抛出错误无关；它通常与在与主项目不同的 Flex SDK 版本中编译的库有关。 [据我所知] 没有可以更改的代码来消除这种情况。您需要重新编译您的库以使用相同版本的 Flex SDK。
