打破 typescript-0.9.0

错误是 bash-3.2$ tsc helloworld.ts

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

有谁知道发生了什么或此错误消息意味着什么？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。没有使用足够的参数调用方法，这导致了这个奇怪的错误。这是错误补丁差异。

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：

这里是所有的依赖typescript.ts

///<reference path='diagnostics.ts' />
///<reference path='flags.ts' />
///<reference path='nodeTypes.ts' />
///<reference path='hashTable.ts' />
///<reference path='ast.ts' />
///<reference path='astWalker.ts' />
///<reference path='astWalkerCallback.ts' />
///<reference path='astPath.ts' />
///<reference path='astLogger.ts' />
///<reference path='binder.ts' />
///<reference path='base64.ts' />
///<reference path='sourceMapping.ts' />
///<reference path='emitter.ts' />
///<reference path='errorReporter.ts' />
///<reference path='parser.ts' />
///<reference path='printContext.ts' />
///<reference path='scanner.ts' />
///<reference path='scopeAssignment.ts' />
///<reference path='scopeWalk.ts' />
///<reference path='signatures.ts' />
///<reference path='symbols.ts' />
///<reference path='symbolScope.ts' />
///<reference path='tokens.ts' />
///<reference path='typeChecker.ts' />
///<reference path='typeCollection.ts' />
///<reference path='typeFlow.ts' />
///<reference path='types.ts' />

///<reference path='referenceResolution.ts' />
///<reference path='precompile.ts' />
///<reference path='incrementalParser.ts' />
///<reference path='declarationEmitter.ts' />

过去我也看到过由格式不完全正确的注释引起的问题。我建议始终在结束斜杠之前放置一个空格（即使我认为这不是您的问题），即

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

不是

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