The type "By" has no common properties with the type "Locator"

Question

I have a problem, when I try to rebuild my project, I get the following error:

Type 'By' has no properties in common with type 'Locator'

Can someone please point me in the right direction?

Answer 1

This is a bug in Protractor 4.x / Webdriver. The method elementexpects, Locatorbut by.cssreturns an object webdriver.by. To fix this compilation error, you need to attribute it to Locatorhow:

import { Locator } from 'protractor/built/locators';
...
element(<Locator>by.css('h1'))

Answer 2

Verify that TypeScript "TypeScript 2.2" is installed. You should not get an error if you are using "TypeScript 2.2".
