打破typescript-0.9.0

错误是 bash-3.2 $ tsc helloworld.ts

/Users/tadams/git/typescript/bin/tsc.js:42270

是否有人知道发生了什么或此错误消息的含义是什么？在Mac OS X 10.8上运行typescript-0.9.0。谢谢！

更新：   打字稿.9中有一个错误。一个方法没有调用足够的参数导致这个奇怪的错误。这是bug补丁差异。

您需要确保所有依赖项都可用，特别是在我想象的示例中flags.ts：

以下是typescript.ts

的所有依赖关系

///<reference path='diagnostics.ts' />
///<reference path='flags.ts' />
///<reference path='nodeTypes.ts' />
///<reference path='hashTable.ts' />

我在过去也看到过没有格式正确的评论引起的问题。我建议总是在结束斜线前加一个空格（即使我认为这不是你的问题），即

///<reference path='/Users/tadams/git/typescript/src/compiler/typescript.ts' />

不

///<reference path='/Users/tadams/git/typescript/src/compiler/typescript.ts'/>
