Puppeteer 中的默认 executablePath 是什么？

Question

This initialization works well even if we are not passing executablePath in LaunchOptions in puppeteer.launch()

const browser = await puppeteer.launch();

What is default value of executablePath ?

Answer 1

The default value of the executablePath option in the puppeteer.launch() function is null . This means that Puppeteer will use the default installation of Chrome or Chromium on the system to launch the browser.

If you have multiple versions of Chrome or Chromium installed on your system, or if you want to use a specific version of the browser, you can specify the path to the executable in the 'executablePath' option. For example:

const browser = await puppeteer.launch({
  executablePath: '/path/to/chrome'
});

If you do not specify a value for the executablePath option, Puppeteer will try to find the default installation of Chrome or Chromium on the system. On Windows, this is usually C:\Program Files (x86)\Google\Chrome\Application\chrome.exe . On macOS and Linux, Puppeteer will try to use the chrome or chromium executable in the PATH .

Answer 2

The path will change based on the platform that you install puppeteer on.

https://github.com/puppeteer/puppeteer/blob/main/packages/puppeteer/src/node/install.ts
has methods for finding that path.
