解决方案是引用方式改下下面的方法:
`import { ImageCropper } from "@candies/image_cropper";`
使用如下:
```typescript
import * as image_cropper from "@candies/image_cropper";
import { ImageCropper } from "@candies/image_cropper";
import { image } from '@kit.ImageKit';
```typescript
import * as image_cropper from "@candies/image_cropper";
import { ImageCropper } from "@candies/image_cropper";
import { image } from '@kit.ImageKit';
```typescript
export interface ImageCropperConfigOptions {
