Cannot use CodeceptJs on MacOS

What are you trying to achieve?

Run CodeceptJs tests on MacOs with Safari and/or Chrome. I executed the command npx codecptjs run

What do you get instead?

Could not load helper WebDriver from module ‘./helper/WebDriver’:
Required modules are not installed.

RUN: [sudo] npm install -g webdriverio@^5.2.2

A colleague of mine had the same problem. It seems that newer versions of WebDriverIO (> 5.2.2) are breaking CodeceptJS.

We fixed by removing the newer WebDriverIO version with npm remove -g webdriverio and installing the version Codecept asks for: npm install -g webdriverio@5.2.2 (we had to remove the ^ from the command to install the correct version)

Edit: webdriverio v5.2.2 gave the error this.browser.setWindowSize is not a function. With v5.7.8 we got it working.
