We have AngularJS protractor tests. The process is to set up and run these steps in order:
$ npm install
$ webdriver-manager update --ie32 --ignore_ssl
$ gul
I faced the same issue. Just install or update the protractor. If you still installed the protractor also Do the following steps, run the following in cmd prompt or PowerShell
npm install protractor -g
npm install webdriver-manager -g
If you got the error as running in the background, check the running processor and close all the running processor and try.
After the above steps run the following
webdriver-manager update
webdriver-manager start
