已尝试操作 #

• 删除node_modules和package-lock.json后重新安装依赖，问题未解决

原因分析 #

1. CSS语法错误：报错指向src/index.css，其中存在两处语法问题：
   • .contact类中使用单引号包裹属性值（background:'#f1f1f1'、border-radius:'10px'），生产构建的CSS解析器对这类语法兼容性差；
   • .text404类中存在多余分号（color: midnightblue !important;;），属于无效CSS语法，触发解析异常。
2. 依赖版本冲突：项目同时安装了@material-ui/core（v4）和@mui/material（v5），二者为同一UI库的不同大版本，会干扰webpack样式loader的正常工作流程。

解决方案 #

1. 修复CSS语法错误 #

修改src/index.css中的错误代码：

/* 修复.contact类的属性值引号问题 */
.contact{
  margin: auto !important;
  background-color: #ebebeb !important;
  background: #f1f1f1 !important;
  border-radius: 10px !important;
}

/* 移除.text404类的多余分号 */
.text404{
  color: midnightblue !important;
}

2. 清理冲突依赖 #

卸载v4版本的Material-UI依赖，避免与v5版本冲突：

npm uninstall @material-ui/core @material-ui/icons

重新安装依赖：

npm install

3. 重新执行构建 #

npm run build
