项目场景：

问题描述：

warning  in ./src/components/SideBar.vue

There are multiple modules with names that only differ in casing.
This can lead to unexpected behavior when compiling on a filesystem with other case-semantic.
Use equal casing. Compare these module identifiers:

        }

原因分析：

提示：这里填写问题的分析：
例如：Handler 发送消息有两种方式，分别是 Handler.obtainMessage()和 Handler.sendMessage()，其中 obtainMessage 方式当数据量过大时，由于 MessageQuene 大小也有限，所以当 message 处理不及时时，会造成先传的数据被覆盖，进而导致数据丢失。

解决方案：

此类问题通常是router 里面的

index.js 的文件 引入组件的时候 单词写错了，注意一下组件的大小写就好了。

改成
即可。
