我有没有困难，直到这一点直接从MXMLC命令行。在编写ActionScript 3的code我遇到了一个依赖问题。

I've had not trouble until this point directly from MXMLC command line. While compiling Actionscript 3 code I ran into a dependency problem.

import flash.filesystem;

和我得到

    Error: Definition flash:filesystem could not be found

有另外一个或两个文件相关的库如文件流。我在哪里可以找到这些标准库，我怎么可能把它们添加到我的MXMLC库路径？

There are another or two file-related libraries such as filestream. Where can I find these standard libraries and how might I add them to my MXMLC library PATH?

推荐答案

什么是您要使用特定的类？如果要导入所有的类在 flash.filesystem 包，你需要一个 * 在该月底import语句。否则，你需要追加的类名（S）。类似于下列之一：

What are the specific classes you are trying to use? If you want to import all of the classes in the flash.filesystem package you need a * at the end of that import statement. Otherwise you need to append the class name(s). Something like one of these:

import flash.filesystem.*;

或

import flash.filesystem.File;

这可能是一个问题的另一件事是在你的Flex-config.xml中（或空气-config.xml文件）文件，该文件是SDK的一部分价值。您可能需要配置这包括类在AIR SDK等。

The other thing that might be an issue is the values in your flex-config.XML (or air-config.xml) file that is part of the SDK. You might need to configure this to include the classes in the AIR sdk, etc.
