运行Puppeteer报错：无法找到Chrome（版本118.0.5993.70）

问题描述 #

我是编程新手，表述若有不当请见谅。我编写了一个使用Puppeteer的.js程序，在台式机上运行正常，但在笔记本电脑上运行时出现以下错误：

C:\Users\andre\OneDrive\Coding\Projects\Websscraper\node_modules\puppeteer-core\lib\cjs\puppeteer\node\ProductLauncher.js:298
                    throw new Error(`Could not find Chrome (ver. ${this.puppeteer.browserRevision}). This can occur if either\n` +
                          ^

Error: Could not find Chrome (ver. 118.0.5993.70). This can occur if either
 1. you did not perform an installation before running the script (e.g. `npm install`) or
 2. your cache path is incorrectly configured (which is: C:\Users\andre\.cache\puppeteer).
For (2), check out our guide on configuring puppeteer at https://pptr.dev/guides/configuration.

Node.js v20.7.0

我已确认Puppeteer已安装，检查了Package.Json（如下所示），且已将Chrome更新至最新版本：

{
  "name": "websscraper",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "dependencies": {
    "axios": "^1.6.0",
    "cheerio": "^1.0.0-rc.12",
    "dotenv": "^16.3.1",
    "express": "^4.18.2",
    "node-notifier": "^10.0.1",
    "nodemon": "^3.0.1",
    "open": "^9.1.0",
    "pupeteer": "^0.0.1",
    "puppeteer": "^21.4.1",
    "twilio": "^4.19.0"
  }
}

解决办法 #

• 清理重复依赖：你的package.json里存在拼写错误的pupeteer和正确的puppeteer两个重复依赖，先卸载错误的依赖，再重新安装正确版本：

  npm uninstall pupeteer
  npm uninstall puppeteer && npm install puppeteer
  

  这能避免依赖冲突，确保Puppeteer安装完整。

• 指定本地Chrome路径：如果Puppeteer仍无法找到Chrome，直接在代码中指定笔记本上Chrome的实际安装路径。Windows系统下Chrome默认路径通常为C:\Program Files\Google\Chrome\Application\chrome.exe，修改你的启动代码：

  const browser = await puppeteer.launch({
    executablePath: 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe',
    // 保留你的其他配置项
  });
  

  注意路径中的反斜杠需要转义，也可以用正斜杠替代：'C:/Program Files/Google/Chrome/Application/chrome.exe'。

• 重置Puppeteer缓存：删除错误提示中的缓存文件夹C:\Users\andre\.cache\puppeteer，然后重新执行npm install，让Puppeteer重新下载对应版本的Chrome，同时确保该缓存文件夹有读写权限。
