【问题标题】:How to debug a TSLint error?如何调试 TSLint 错误?
【发布时间】:2017-09-20 11:43:21
【问题描述】:

我正在使用 webstorm 和 Angular 2 应用程序。发生了一些变化,似乎 tslint 不喜欢我的 tslint.json 文件。

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

我不知道如何开始调试它,因为错误没有表明(我可以看到)tslint 文件中的问题所在。

顺便说一句,我已经使用了项目附带的默认 tslint 文件,我没有做任何更改。

是否有可以在我的 tslint 文件上运行的验证命令来显示错误在哪里?

节点:7.8 TSLint:5.1

    【解决方案1】:

    您可以在终端上运行 ng lint 命令,它会准确地向您显示文件的哪一行出现此错误。这也取决于你如何设置你的 package.json。

    【讨论】:

    • 我得到:“您必须在 angular-cli 项目中才能使用 lint 命令。”但“ng serve”工作正常。
    • 好吧,在这种情况下,您的 package.json 中似乎配置错​​误。缺少 lint 命令或全局和本地角度版本不匹配。
    【解决方案2】:

    node_modules/tslint/lib/linter.js 中找到applyRule 定义并替换行:

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

    与:

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

    我提交了issue
