从 pact-js 存储库运行示例时无法找到本机模块错误

Question

我正在运行 pact-js 存储库中的消费者示例。重现下面的示例（我修改了文件以避免打字稿）：

import { PactV3, MatchersV3 } from '@pact-foundation/pact';
import path from 'path';

// Create a 'pact' between the two applications in the integration we are testing
const provider = new PactV3({
  dir: path.resolve(process.cwd(), 'pacts'),
  consumer: 'MyConsumer',
  provider: 'MyProvider',
});

// API Client that will fetch dogs from the Dog API
// This is the target of our Pact test
getMeDogs = (from) => {
  return axios.request({
    baseURL: this.url,
    params: { from },
    headers: { Accept: 'application/json' },
    method: 'GET',
    url: '/dogs',
  });
};

const dogExample = { dog: 1 };
const EXPECTED_BODY = MatchersV3.eachLike(dogExample);

describe('GET /dogs', () => {
  it('returns an HTTP 200 and a list of docs', () => {
    // Arrange: Setup our expected interactions
    //
    // We use Pact to mock out the backend API
    provider
      .given('I have a list of dogs')
      .uponReceiving('a request for all dogs with the builder pattern')
      .withRequest({
        method: 'GET',
        path: '/dogs',
        query: { from: 'today' },
        headers: { Accept: 'application/json' },
      })
      .willRespondWith({
        status: 200,
        headers: { 'Content-Type': 'application/json' },
        body: EXPECTED_BODY,
      });

    return provider.executeTest( async (mockserver) => {
      // Act: test our API client behaves correctly
      //
      // Note we configure the DogService API client dynamically to 
      // point to the mock service Pact created for us, instead of 
      // the real one
      dogService = new DogService(mockserver.url);
      const response = await dogService.getMeDogs('today')

      // Assert: check the result
      expect(response.data[0]).to.deep.eq(dogExample);
    });
  });
});

我创建了一个新目录并执行了

npm init

。我的 package.json 看起来像：

{
  "name": "repo1",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "@pact-foundation/pact": "^12.1.1"
  },
  "type": "module"
}

还有几件事：

• 节点版本20.10.0
• npm 版本 10.2.3
• 平台是macOS
• node-gyp 全局安装
• 有海湾合作委员会
• 有品牌

运行上面的示例（保存到 cons.js）会生成以下错误：

 [15:38:11.420] ERROR (28229): [email protected]: Failed to find native module for darwin-x64: TypeError: Cannot read properties of undefined (reading 'pactffiInitWithLogLevel')

有关如何运行此程序的任何指示都会有所帮助。

Answer 1

我必须升级笔记本电脑上的操作系统版本。操作系统升级后安装node、npm、Xcode开发工具后，我不再收到错误。

Answer 2

我知道OP有macos，但我在docker中使用

node:18-alpine

图像运行时遇到了同样的问题。我的解决方案是迁移到稍微重一点的图像：

node:18-slim

。

根本原因隐藏在吞咽异常中：

Error: Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by /app/node_modules/@pact-foundation/pact-core/prebuilds/linux-x64/libpact_ffi.so)
    at Object.Module._extensions..node (node:internal/modules/cjs/loader:1452:18)
    at Module.load (node:internal/modules/cjs/loader:1197:32)

此文件未在

node:18-alpine

中呈现。

调试它的另一个指针是

bash

进入docker镜像并在libpact二进制文件上运行

ldd

（更改你的路径）：

ldd /app/node_modules/@pact-foundation/pact-core/prebuilds/linux-x64/libpact_ffi.so

如果缺少所需的依赖库，您将看到错误：

ldd /app/node_modules/@pact-foundation/pact-core/prebuilds/linux-x64/libpact_ffi.so
