如何调试TSLint错误？

问题描述：

我正在使用webstorm和Angular 2应用程序。有些东西已经改变，它似乎tslint不喜欢我的tslint.json文件。如何调试TSLint错误？

TSLint: TypeError: Cannot read property '1' of undefined

我不知道如何开始调试它作为错误不表明（我可以看到），其中在tslint文件的问题。

顺便说一句，我采取了项目的默认tslint文件，我没有做任何改变。

是否有一个验证命令，我可以在我的tslint文件上运行，它会告诉我错误在哪里？

节点：7.8 TSLint：5.1

您可以运行纳克皮棉你的终端上命令，它会准确地告诉你在文件中的哪一行数行吧有这个错误。这也取决于你如何设置你的package.json。

我得到：“你必须在角度cli项目中才能使用lint命令。”但“ng服务”工作正常。 –

那么在这种情况下，好像在package.json中配置错了。 lint命令丢失或全局和本地角度版本不匹配。 – amulamul

在node_modules/tslint/lib/linter.js找到applyRule定义和替换行：

error_1.showWarningOnce("Warning: " + error.message);

有：

error_1.showWarningOnce("Warning: " + error.message + " " + error.stack);

我提交的issue。
