Scala-js: Cannot find module 'jsdom'

[japgolly]

Hi. Using 0.6.13 I decided to try out nodejs & jsdom.

The only Scala.JS test setting I set is:

requiresDOM := true

I installed jsdom globally, see here:

> npm list -g jsdom
/usr/lib
└── [email protected] 

However when I run tests I get:

> sbt

Versions are:

> node --version
v7.0.0
> npm --version 
3.10.9

Do you see something I'm missing?

It doesn't work when installed globally (for some reason), so you need to install it per project. Remember to add node_modules to .gitignore :)

Also in Travis the default version of Node is too old so you need to add to your .travis.yml this:

install:
  - . $HOME/.nvm/nvm.sh
  - nvm install stable
  - nvm use stable
  - npm install
  - npm install jsdom

@ochrons Are you able to have a quick look at my .travis.yml? I can't get scalajs-react with jsdom in Travis. It keeps saying "Node.js isn't connected".

[japgolly]

Same issue as #2378?

[ochrons]

The node/jsdom setup works with spa tutorial (https://travis-ci.org/ochrons/scalajs-spa-tutorial/builds/184434514) but perhaps in your setup there are too many concurrent tests and that causes issues? Can you try making tests run in serial on Travis?

Thanks @ochrons. I added set parallelExecution in ThisBuild := false to Travis and it seems to have fixed it.
