Ionic emulate with live reload fails

Ionic Framework ionic-v3

Hi,

replay:

on a mac:

ionic start foo
cd foo
npm install --save-dev karma
echo “var Server = require(‘karma’).Server;” >> gulpfile.js
ionic emulate ios --target=“iPhone-6s” -slc

Output:

The same thing happens to me on Ubuntu when trying to run on Android with live reload.

A solution is to load karma inside of the task (avoid loading it during ionic calls).

The reason is a library version problem which might be the cause for various live reloading error message as well.

gulp.task('test', function (done) {
var karma = require('karma').Server;

new Server({
	configFile: __dirname + '/karma.conf.js',
	singleRun: true
}, done).start();

});
