在本地找不到预期的浏览器 chrome

Question

此 Meteor 代码使用“puppeteer 8.0.0”、“puppeteer-core 10.0.0”、puppeteer-extra 3.1.18”和“puppeteer-extra-plugin-stealth 2.7.8”，它给出以下错误：

错误：无法在本地找到所需的浏览器（chrome）。运行npm install以下载正确的 Chromium 修订版 (884014)。

尝试“npm install”无济于事。在线阅读，尝试从 package.json 依赖项中删除 "puppeteer-core": "^10.0.0" 但无济于事。

非常感谢任何帮助。谢谢

const puppeteer = require('puppeteer-extra');
const nameH = require('./NameH');

const puppeteerOptions = {
    headless: true,
    ignoreHTTPSErrors: true,

}

let browser;
let pageNameH;

const init = async () => {
    const StealthPlugin = require('puppeteer-extra-plugin-stealth');
    console.log('1')         //>>>>>>>>>>>> Prints 1
    puppeteer.use(StealthPlugin());

Answer 1

也许你可以尝试这个，它对我在 linux(centOS)、puppeteer(10.2.0) 上有效。

cd ./node_modules/puppeteer
npm run install

如果失败，您还可以尝试运行：

cd ./node_modules/puppeteer
npm install

这会将 chromium 下载到 ./node_modules/puppeteer/.local-chromium

Answer 2

通过运行此命令手动安装 chromium 来修复它。

node node_modules/puppeteer/install.js

Answer 3

我有同样的问题。我检查了我的环境变量，即使 PUPPETEER_SKIP_CHROMIUM_DOWNLOAD 设置为 false，它仍然无法工作。在我删除变量（对于 mac 取消设置 PUPPETEER_SKIP_CHROMIUM_DOWNLOAD）后，它起作用了。

相关依赖：

  "dependencies": {
    "chrome-aws-lambda": "^10.0.0",
    "puppeteer-core": "^10.0.0",
  },
  "devDependencies": {
    "puppeteer": "^10.0.0",
  }

启动铬：

    import chromium from "chrome-aws-lambda";

    const browser = await chromium.puppeteer.launch({
        executablePath: await chromium.executablePath,
    });

Answer 4

如果您在本地测试，请确保您已将 puppeteer 安装为开发依赖项。具体来说

npm install puppeteer --save-dev

https://github.com/alixaxel/chrome-aws-lambda/wiki/HOWTO:-Local-Development#workaround

这种方法使我们能够依靠 puppeteer 进行本地开发，并依靠 puppeteer-core 进行生产部署。
