41**适配指导**
42
43将调用ohos.commonEvent中的事件替换成调用@ohos.commonEventManager，比如以下示例代码：
44
45```typescript
46import commonEvent from '@ohos.commonEvent';
47let event: string = commonEvent.Support.COMMON_EVENT_PACKAGE_CACHE_CLEARED;
48```
49
50需要修改成
51
52```typescript
53import commonEventManager from '@ohos.commonEventManager';
54let event: string = commonEventManager.Support.COMMON_EVENT_PACKAGE_CACHE_CLEARED;
55```
