Bug

What is the current behavior?

When I run Jest, it fails immediately with Cannot find module 'request', but I don’t require request myself, it’s part of the Jest dependency tree.

λ npm test -- --no-cache

> nima-bot@0.0.1 test C:\Users\E\Documents\GitHub\nima
> jest "--no-cache"

 FAIL  src\__tests__\modules\calc.js

If the current behavior is a bug, please provide the steps to reproduce and either a repl.it demo through https://repl.it/languages/jest or a minimal repository on GitHub that we can yarn install and yarn test.

I’ve pushed a branch named wtf-jest to a branch that you can test it out on: https://github.com/denizdogan/nima/tree/wtf-jest

git clone -b wtf-jest https://github.com/denizdogan/nima
cd nima
yarn i
yarn test

What is the expected behavior?

I expect Jest to run my test suites.

Please provide your exact Jest configuration and mention your Jest, node, yarn/npm version and operating system.

NPM 5.6.0 Node.js 9.4.0 Jest 22.1.4 Windows 10 (64-bit)

Something is up with your installed tree, doing npm dedupe && npm prune && npm install makes the test green.

Also, you should install the babel core bridge if you’re using babel 7 (see https://facebook.github.io/jest/docs/en/getting-started.html#additional-configuration)

I had the same problem. npm list request said UNMET PEER DEPENDENCY request@2.88.2. Calling npm i -D jest fixed the issue
