我正在开发我的Nuxt.js应用程序。数据库我选择了Milvus。我想做相似度搜索，但在浏览器控制台中遇到错误。

我有以下代码：

应用程序.vue

// Other code

<script setup lang="ts">
import { MilvusClient } from "@zilliz/milvus2-sdk-node";

// I also have other code not related to Milvus here, but I don't think it's relevant

(async () => {
  const milvusClient = new MilvusClient({
    address: "localhost:19530",
    username: "",
    password: "",
  });

  // Similarity search
  const test = await milvusClient.search({
    collection_name: "xxxxx", // My collection name here
    vector: [ // My vector here ],
  });

  // Sort the results by score in descending order
  const sortedResults = test.results.sort((a, b) => b.score - a.score);

  // Display the descriptions with scores
  sortedResults.forEach((result) => {
    console.log(`[${result.score}]: ${result.description}`);
  });
})();
</script>

包.json

{
  "name": "nuxt-app",
  "private": true,
  "type": "module",
  "scripts": {
    "build": "nuxt build",
    "dev": "nuxt dev",
    "generate": "nuxt generate",
    "preview": "nuxt preview",
    "postinstall": "nuxt prepare"
  },
  "devDependencies": {
    "autoprefixer": "^10.4.16",
    "nuxt": "^3.9.3",
    "postcss": "^8.4.33",
    "tailwindcss": "^3.4.1",
    "vue": "^3.4.6",
    "vue-router": "^4.2.5"
  },
  "dependencies": {
    "@nuxt/ui": "^2.10.0",
    "@zilliz/milvus2-sdk-node": "^2.3.5",
    "nuxt-security": "^1.1.0"
  }
}

正如您在上面看到的app.vue，我使用Milvus 2 Node.js SDK，但我在浏览器控制台中收到以下错误：

TypeError: Class extends value undefined is not a constructor or null

我一般性地搜索了这个错误，并在 StackOverflow 上找到了多个答案，说这可能是由循环依赖引起的。我曾经dpdm发现潜在的循环依赖。

我运行了以下命令：

dpdm app.vue

但没有发现循环依赖：

✔ [0/0] Analyze done!
• Dependencies Tree
  - 0) app.vue

• Circular Dependencies
  ✅ Congratulations, no circular dependency was found in your project.

• Warnings

我按照官方示例尝试了很长一段时间，但无法解决此错误。
