[HBuilder] 11:35:24.624 ERROR Build failed with errors.
[HBuilder] 11:35:24.657 项目 'tx_carling_buyer_app' 发布微信小程序失败.
错误文件是：Error: Compile failed at components/description/index.vue
在这个文件我发现事件我是这样写的：
@click.stop="preview(img, item.compute(item))"
把这句改成：
@click.stop="preview(img, item)"
就成功了
在写事件的时候，不能反复套函数
