ESLint：打字稿中未定义“部分”

Question

ESLint 无法识别Partial打字稿，但编译后的模块没有给出任何错误。

const initialState: IAuthState = {
  authenticated: false,
  processing: false,
};

const authReducer = (state: IAuthState = initialState, action: any): IAuthState => {
  const State = (newState: Partial<IAuthState>): IAuthState => ({...state, ...newState});

  switch (action.type) {
    case Actions.SIGN_IN_PROCESS_INITIATED:
      return State({processing: true});

    case Actions.SIGN_IN_PROCESS_FAILED:
      return State({processing: false});

    default:
      return state;
  }
};

我知道这可以被抑制，// eslint-disable-next-line no-undef但我仍然想要一个解释和一个永久的解决方案，这样我就不会得到这个错误Error。

我前段时间遇到过类似的情况，并通过安装@typescript-eslint/parser为 devDependency 并将其包含在 eslint 配置中来修复它：

  "extends": [..., "@typescript-eslint/parser"],
