Even without jest global, fresh install doesn't work. You either need to add jest-environment-node
to the npm install
command, or take out peer dependencies. Why not take out peer dependencies, they just complicate things?
Repro steps without global jest:
- Create a directory and
cd
into it - Put into
package.json
:
{
"scripts": {
"test": "jest"
},
"jest": {
"preset": "jest-puppeteer"
}
}
npm install --save-dev jest-puppeteer puppeteer
Note this warning is printed:
npm WARN [email protected] requires a peer of jest-environment-node@^22.0.0 but none is installed. You must install peer dependencies yourself.
Also note that node_modules/jest-environment-node
doesn't exit.
- Put sample code into test.js
jest test.js
gives this error:
npm test
FAIL ./test.js
● Test suite failed to run
Cannot find module 'jest-environment-node'

npm install --save-dev [email protected]
. Nownpm test
works.

I thought that jest-environment-node
was installed with jest
that's why it is a peer dependency. I will check but if it is not the case it makes sense to add move it into dependencies
.

Ah, I did an npm global install of jest
. (Updated my repro steps.) So even if jest
installed jest-environment-node
, it wouldn't be in <root_dir>/node_modules
.
Can you further explain the technical reason why the peer dependency was needed? Or just try getting rid of the peer dependencies? There's also a peer dependency in packages/jest-puppeteer/package.json; it would be nice to get rid of that too.

I have just tested to install jest locally and it installs jest-environment-node/
. Installing jest
globally is not a good practice, so please install it locally and everything will work.

Even with jest global
I think @neoziro expressly said to not use jest globally but locally and everything will work 😋
I haven't tested myself.

Sorry, I meant "even without jest global", I edited the post.
