|            | COMMON_EVENT_QUICK_FIX_APPLY_RESULT | COMMON_EVENT_QUICK_FIX_APPLY_RESULT |

**适配指导**

将调用ohos.commonEvent中的事件替换成调用@ohos.commonEventManager，比如以下示例代码：

```typescript
import commonEvent from '@ohos.commonEvent';
let event: string = commonEvent.Support.COMMON_EVENT_PACKAGE_CACHE_CLEARED;
```

需要修改成

```typescript
import commonEventManager from '@ohos.commonEventManager';
let event: string = commonEventManager.Support.COMMON_EVENT_PACKAGE_CACHE_CLEARED;
```
