我想在 Raspberry pi 零 w 上使用 puppeteer 运行节点 js 脚本，但我收到了这个错误：

你能告诉我，我能用它做什么吗？

【问题讨论】：

标签： node.js linux npm raspberry-pi puppeteer

【解决方案1】：

Puppeteer 默认使用捆绑的 Chromium。错误说它无法启动它。

您应该手动安装 Chromium 并让 Puppeteer 使用该版本。假设您已将其安装在 /usr/bin/chromium 中，这样的事情就可以完成：

const browser = await puppeteer.launch({
    product: "chrome", executablePath: "/usr/bin/chromium",
})

【讨论】：

应该是 executablePath: '/usr/bin/chromium-browser' 但 product: 'chrome' 是关键

【解决方案2】：

这是让 Chrome 无头和 Puppeteer 在 Raspberry Pi 上工作的基本代码，以及全新安装的 Raspbian Stretch Lite。

sudo apt install chromium-browser chromium-codecs-ffmpeg
sudo apt install npm
npm install puppeteer-core@v1.11.0

在 node.js 中

const puppeteer = require('puppeteer-core');

const browser = await puppeteer.launch({executablePath: '/usr/bin/chromium-browser'});
