Ok so apparently doctrine cache has been deprecated. https://github.com/doctrine/cache/issues/354, So tried installing an older cache library to make it work. You will need to install this version of Doctrine cache using this in your terminal.

`

     composer require doctrine/cache:1.12.1

`

You need to do this before installing the project or you will get the error. I hope this helps someone.

Hey shirleenkneppers

That's weird. How did you get newer cache package? I checked code we do have this package and it's locked on version 1.10.2. I pretend you tried to upgrade project to latest version which we don't recommend to do with downloaded code 'cause you can get issues

Cheers!

Hi @Vladimir

I normally don't update the files. I started getting errors on Yarn watch at chapter 16 and for some reason it just didn't wanted to show any of the changes on the webpage. I tried fixing the errors but as you can imagine that some of these fixes might have required me to do updates on packages. So after a day of struggling to just be able to use the files I found this and it is working fine. I wouldn't have updated if it wasn't needed. I don't remember the errors but they where hindering my progress.

Regards

Anyways good debugging. I'm curious what is the real issue which forced you to update packages, we will try to investigate it... I hope it is not something serious.

Cheers!
