Karma runs on Node.js and is available as a node module via NPM.
First, you need to install Node.js. There are installers for both
Mac and Windows. On Linux, we recommend using NVM.
Global Installation #
This is the recommended way. It will install Karma into your
node_modules directory and create a symlink to its binary.
$ npm install -g karma
$ karma start
Local Installation #
A local installation will install Karma into your current
node_modules. That allows you to have different
versions for different projects.
$ npm install karma
$ ./node_modules/.bin/karma start
