reactjs React + Typescript + ESLint:no-unused-vars仅用于导出的Enum-s

我已经配置了一个基本的React-Typescript项目(由React-react-app创建)。
对于以下文件:MeetingLevels.ts

enum MeetingLevels {
  SiteLeader = 1,
  AreaManager = 2,
  GroupLeader = 3,
  TeamLeader = 4,
}

export default MeetingLevels;

.. npm run lint产生以下错误:

C:\...\models\MeetingLevels.ts
  1:6  warning  'MeetingLevels' is defined but never used  no-unused-vars
  2:3  warning  'SomeLeader' is defined but never used     no-unused-vars
  3:3  warning  'SpaceManager' is defined but never used   no-unused-vars
  4:3  warning  'GroupLeader' is defined but never used    no-unused-vars

但它被用在了这个项目的多个地方。(在IntelliJ IDEA中Shift+单击也可以找到它)-例如:SomeReactFile.tsx

import MeetingLevels from "../../models/MeetingLevels";
 ...

  const mapMeetingButton = (level: number): string => {
    switch (level) {
      case MeetingLevels.SomeLeader:
        return "A_CUSTOM_STRING";
      case MeetingLevels.SpaceManager:
        return "SOME_OTHER_CUSTOM_STRING";

我试图解决这个问题,但显然,我的.eslintrc.js似乎很好。到目前为止,我所尝试的都不起作用,这个ESLint错误只存在于这里。(这是我在项目中唯一的enum

您可以禁用默认的no-unused-vars规则,而使用@typescript-eslint/no-unused-vars(如果未启用):

"@typescript-eslint/no-unused-vars": "warn",
"no-unused-vars": "off"

我想首先导出枚举并将其导入到任何你想要的地方,就像这样:

export enum MeetingLevels {
      SiteLeader = 1,
      AreaManager = 2,
      GroupLeader = 3,
      TeamLeader = 4,
    }

并导入:

import { MeetingLevels } from "../to-the-target";
