Jest: Cannot find module 'request'

[denizdogan]

Do you want to request a _feature_ or report a _bug_?

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

> [email protected] test C:\Users\E\Documents\GitHub\nima
> jest "--no-cache"

npm ERR! Test failed.  See above for more details.

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)

[SimenB]

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)

[denizdogan]

@SimenB Thanks, it works now. I think the docs are outdated with regards to babel-jest though, because 'babel-core@^7.0.0-0' is not found.

[SimenB]

It works on my machine.

$ mkdir test
$ cd test
$ yarn init -y
$ yarn add babel-core@^7.0.0-0
success Saved 1 new dependency.

@SimenB Maybe this is a difference between NPM and Yarn? Or maybe you had the package in your cache? This is what it looks like to me:

Then I figured it might have to do with the apostrophes, so I tried without them:

That's very odd.

I can only guess a windows bug with npm... You can try opening up an issue with them?

[nikolay-borzov]

I had the same problem. npm list request said UNMET PEER DEPENDENCY [email protected].
Calling npm i -D jest fixed the issue
