提问by Roymunson
Is there a way to let my code compile with ts-node even if there is unused property warnings in one line of my .tsfile withoutsetting "noUsedLocals": falsein my tsconfig.jsonfile?
有没有办法让我的代码用 ts-node 编译，即使我的.ts文件的一行中有未使用的属性警告而不"noUsedLocals": false在我的tsconfig.json文件中设置？

Since TypeScript 2.6 you can suppress errors with // @ts-ignore.
从 TypeScript 2.6 开始，您可以使用// @ts-ignore.
A
// @ts-ignorecomment suppresses all errors that originate on the following line. It is recommended practice to have the remainder of the comment following @ts-ignore explain which error is being suppressed.Please note that this comment only suppresses the error reporting, and we recommend you use this comments very sparingly.
一个
// @ts-ignore评论抑制了以下行发起的所有错误。建议的做法是让 @ts-ignore 后面的评论说明正在抑制哪个错误。请注意，此注释仅抑制错误报告，我们建议您非常谨慎地使用此注释。

It is now possible to use _for unused params.
现在可以_用于未使用的参数。
function myFunc(_, b: string) {}
function otherFunc(_, _1, c: string) {} // multiple unsused
