Error during loading of karma-jsdom-launcher on Windows 10

[Ghislain B.]

I'm trying karma-jsdom-launcher for the first time and I'm getting the following error when starting karma:

Error during loading "C:\myProject\node_modules/karma-jsdom-launcher" plugin:
  Cannot find module 'jsdom'

If you look closely, this is due to the differences of slashes with Windows and Linux. The last slash is a forward slash /, while the two first ones are backward slash \. Users on Mac or Linux, probably don't see this.

Any other launchers, like karma-phantomjs-launcher or karma-chrome-launcher are working fine.

Have you installed jsdom? You have to do it manually (depending on your node version), as it is only listed as a peer dependency.

Oh right, my bad, I didn't see your extra note under the installation. Thanks for the help and the package :)
