微信小程序开发错误：WXML 文件编译错误 -1: 缺少 img 标签闭合标签

The error is caused by the missing closing tag </img> for the <img> element within the <button> element. \n\nTo fix the error, you need to add the closing tag </img> after the alt attribute of the <img> element. Here's the corrected code:\n\nhtml\n<button class='scan-btn' bindtap='scanBarcode'>\n <img src='../../tools/scanIcon.jpg' alt='Scan Barcode'></img>扫码获取邮件编号\n</button>\n\n\nAfter making this change, the error should be resolved.'}
