Actual Behavior

Unable to resolve signature of method decorator when called as an expression.
Experimental support for decorators is a feature that is subject to change in a future release. Set the 'experimentalDecorators' option in your 'tsconfig' or 'jsconfig' to remove this warning.

Steps to reproduce the bug

// a.ts
export function autoBind(
  target: Record<string, any>,
  propertyKey: string,
  { configurable, enumerable, value: fn }: TypedPropertyDescriptor<(...arg: any[]) => any>
): TypedPropertyDescriptor<(...arg: any[]) => any> {
  return {
    configurable,
    enumerable,
    get(): (...arg: any[]) => any {
      if (!fn) {
        throw new Error('函数不得为空');
      }
      return fn.bind(this);
    }
  };
}
// b.ts
import { autoBind } from './a';
class B {
  @autoBind
  private test(): void {
    console.log(this);
  }
}

I can't seem to reproduce this. My best guess is that TypeDoc isn't seeing your config file.
