Adobe Flash Builder（1046：找不到类型或不是编译时常量）

Question

我是第一次使用 Adob​​e Flash Builder，我正在尝试创建一个 Flex 项目。我将在 nodeJS 应用程序中嵌入 Flash 游戏，所以我使用https://github.com/sinnus/socket.io-flash。 Socket.io-flash 需要 websocketJS，我已将 socket.io-flash 文件夹（直接来自 github）和 websocketJS 文件夹（也来自 github）添加到 Flash Builder 的源路径（因此文件应该在它们被识别时被识别）是进口的 - 他们是）。我收到两个导入的错误：

1046: Type was not found or was not a compile-time constant: SocketIOEvent.

还有……

1046: Type was not found or was not a compile-time constant: SocketIOErrorEvent.

就像我说的，导入行很好（那里没有抛出错误）-错误来自方法声明-这是我的 .mxml 文件：

我已经用 '**' 封装了引发错误的行（由于某种原因，导入的内容有问题）。在我的 Flash Builder 项目中，libs 文件夹、websocketJS 文件夹和 socket.io-flash 文件夹中都有，它们都已添加到源路径中。任何帮助将不胜感激 - 谢谢！

函数“logMessage”根本没有定义。使用“trace”作为替代（例如 trace(event.type + ":" + event.text);
