SpecReporter is not a constructor error when runni

When I try to run ng e2e or direct protractor command I get this error :

回答1:

this is because of a breaking change in Jasmine. Change your protractor config file to have:

var SpecReporter = require('jasmine-spec-reporter').SpecReporter;

instead of:

var SpecReporter = require('jasmine-spec-reporter');

回答2:

You need to do like this following:

const SpecReporter = require('jasmine-spec-reporter').SpecReporter;

jasmine.getEnv().addReporter(new SpecReporter());
