Chrome headless doesn't launch on UNIX,谷歌无头浏览器不能在unix运行,要安装对应的依赖侯才能正常运行无头模式。

具体解决办法参看 https://wokan.chawen.org/post/1167

Chrome headless doesn't launch on Windows

Some chrome policies might enforce running Chrome/Chromium with certain extensions.

Puppeteer passes --disable-extensions flag by default and will fail to launch when such policies are active.

To work around this, try running without the flag:

const browser = await puppeteer.launch({

ignoreDefaultArgs: ['--disable-extensions'],

});

Context: issue 3681.

Chrome headless disables GPU compositing

Chrome/Chromium requires --use-gl=egl to enable GPU acceleration in headless mode.

const browser = await puppeteer.launch({
  headless: true,
  args: ['--use-gl=egl'],
});

Chrome is downloaded but fails to launch on Node.js 14

If you get an error that looks like this when trying to launch Chromium:

(node:15505) UnhandledPromiseRejectionWarning: Error: Failed to launch the browser process!

spawn /Users/.../node_modules/puppeteer/.local-chromium/mac-756035/chrome-mac/Chromium.app/Contents/MacOS/Chromium ENOENT

This means that the browser was downloaded but failed to be extracted correctly. The most common cause is a bug in Node.js v14.0.0 which broke extract-zip, the module Puppeteer uses to extract browser downloads into the right place. The bug was fixed in Node.js v14.1.0, so please make sure you're running that version or higher. Alternatively, if you cannot upgrade, you could downgrade to Node.js v12, but we recommend upgrading when possible.

Setting Up Chrome Linux Sandbox

In order to protect the host environment from untrusted web content, Chrome uses multiple layers of sandboxing. For this to work properly, the host should be configured first. If there's no good sandbox for Chrome to use, it will crash with the error No usable sandbox!.

If you absolutely trust the content you open in Chrome, you can launch Chrome with the --no-sandbox argument:

const browser = await puppeteer.launch({

args: ['--no-sandbox', '--disable-setuid-sandbox'],

});

NOTE: Running without a sandbox is strongly discouraged. Consider configuring a sandbox instead.

There are 2 ways to configure a sandbox in Chromium.

[recommended] Enable user namespace cloning

User namespace cloning is only supported by modern kernels. Unprivileged user namespaces are generally fine to enable, but in some cases they open up more kernel attack surface for (unsandboxed) non-root processes to elevate to kernel privileges.

sudo sysctl -w kernel.unprivileged_userns_clone=1

[alternative] Setup setuid sandbox

The setuid sandbox comes as a standalone executable and is located next to the Chromium that Puppeteer downloads. It is fine to re-use the same sandbox executable for different Chromium versions, so the following could be done only once per host environment:

# cd to the downloaded instance

cd /node_modules/puppeteer/.local-chromium/linux-/chrome-linux/

sudo chown root:root chrome_sandbox

sudo chmod 4755 chrome_sandbox

# copy sandbox executable to a shared location

sudo cp -p chrome_sandbox /usr/local/sbin/chrome-devel-sandbox

# export CHROME_DEVEL_SANDBOX env variable

export CHROME_DEVEL_SANDBOX=/usr/local/sbin/chrome-devel-sandbox

You might want to export the CHROME_DEVEL_SANDBOX env variable by default. In this case, add the following to the ~/.bashrc or .zshenv: ...
