提示找不到组件 index-card

build 之后，目录结构如下：
/pages/components/about.wxc
/pages/components/float-avatar.wxc
/pages/components/index-card.wxc
/pages/components/qrcode.wxc
/pages/components/setting.wxc
然后还是提示找不到components；其他minui的都没报错
```shell
Error: Component is not found in path "pages/components/index-card" (using by "pages/index")
```
