test

import puppeteer from 'puppeteer'

describe('academy', function() {
  let browser: puppeteer.Browser;
  let page: puppeteer.Page;

  before(async function() {
    browser = await puppeteer.launch({ headless: true })
    page = await browser.newPage();
  });
});

Step 1

Error shows when npm run test

$ npm run test
Error: Failed to launch chrome! spawn /node_modules/puppeteer/.local-chromium/linux-669486/chrome-linux/chrome ENOENT

• ENOENT: No such file or directory
• Error No Entry or Error No Entity

Step 2

Check existence of /node_modules/puppeteer/.local-chromium/linux-669486/chrome-linux/chrome

$ ls -lha /node_modules/puppeteer/.local-chromium/linux-669486/chrome-linux/chrome
-rwxr-xr-x    1 pptruser pptruser  822.8M Jun 24 11:35 /node_modules/puppeteer/.local-chromium/linux-669486/chrome-linux/chrome

Step 3

Use ldd (Link Dynamic Dependencies) command to check dependencies

$ ldd /node_modules/puppeteer/.local-chromium/linux-669486/chrome-linux/chrome | grep not
Error loading shared library ld-linux-x86-64.so.2: No such file or directory (needed by ./chrome)
