v-model： searchInfo is not defined

v-model： searchInfo is not defined

一个检索输入框，输入内容，点击查询按钮，代码如下

 "true" class="demo-form-inline">
      <el-form-item>
        <el-input
            v-model="searchInfo"
            class="search_name"
            placeholder="输入文件名称查询">
        el-input>
      el-form-item>
      <el-form-item>
        <el-button
            link
            type="primary"
            icon="Search"
            @click="onSearch()"
            class="el-icon-search">查询
        el-button>
      el-form-item>
 .....
data() {
    return {
      ruleForm: {
        userId: '',
        userName: '',
        userDate: '',
        userAddress: ''
      },
      tableData: [],
      searchInfo: "",
      dialogVisible: false,
    }
  },
。。。
  onSearch() {
      let postData = this.qs.stringify({
        userName: this.searchInfo
      });
      this.axios({
。。。。

本地运行是可以的，输入关键字，点击查询，正常，但是进行打包，打包命令如下，npm run build，打包后的dist文件夹部署在服务器的nginx下，然后输入框不让输入，点击输入就报错如下：

其他文件package.json：

{
  "name": "minio-upload-web",
  "version": "0.0.0",
  "scripts": {
    "dev": "vite",
    "build": "vite build",
    "preview": "vite preview --port 4173"
  },

    "axios": "^0.27.2",

    "@vitejs/plugin-vue": "^3.0.1",

}

初始化修改为 obj:{searchInfo:''}, 即可了
