webpacker:install requires yarn

Hi Guys,
Great tutorial!
However, when you follow the tutorial and trying to start the server for the first time you get a huge stack trace dump because yarn is not installed. It is actually saying in the stack dump, but it can be quite intimidating for the uninitiated. 😎
I would add it to step 1 after the line "In this exercise, you will use Ruby on Rails to build a web app."
Cheers,
Marton
Thanks @martonnagy for reporting. I did not encounter this issue, but maybe I already had yarn, or the Windows installer includes it. I'll investigate this for the next refresh of the tutorial.
Thanks @jasonjoh
According to their docs, Yarn is a pre-req.
Before you install Rails, you should check to make sure that your system has the proper prerequisites installed. These include:
- Ruby
- SQLite3
- Node.js
- Yarn
