Hi @nishanthgurung
As you can see, protractor is a devDependency: https://github.com/rochejul/gulp-angular-protractor/blob/master/package.json#L51

As explained here, you should declare which version you should use: https://github.com/rochejul/gulp-angular-protractor#side-dependencies

The goal was to let you the ability to use the protractor version (since peerDependency is not yet available)

Regards
