Please include code that reproduces the issue.

1. upgrade puppeteer from 1.1.1 to 1.5.0 version

What is the expected result? to run puppeteer

What happens instead? error:

    Cannot find module './types/standard' from 'index.js'

      at Resolver.resolveModule (../node_modules/jest-resolve/build/index.js:210:17)

if I return to 1.1.1 version - puppeteer runs and pass the test

Cause: The error happens because puppeteer v1.5 started to use mime@2.x: https://github.com/GoogleChrome/puppeteer/commit/37cc9f567d9c2d8da1eeb630d13202e95a48cbed#diff-b9cfc7f2cdf78a7f4b91a753d10865a2R32).

in mime@2.x they added a require to a JSON file: https://github.com/broofa/node-mime/blob/master/index.js#L4

Most “copy-paste” Jest configurations doesn’t support loading JSONs as-is, so that’s probably the cause.

To solve the problem: Simply add “json” to the moduleFileExtensions entry in the jest property in your package.json file.

// package.json

"jest": {
  "moduleFileExtensions": [
    "json"
  ]
}

- You probably already have other extensions there, so make sure not to remove them but to add “json” in addition.

Also had the same error and downgrading worked. Is there no other fix though?
