Error when scaffolding new app - Cannot find name 'Buffer'

Description

I just wanted to setup a new blank app using rc-apps create and received the following error after filling out the prompts:

❯  216_rocketchat-app-otrs  rc-apps create
Let's get started creating your app.
We need some information first:

Workaround

Running npm install @types/node within the current working directoy where the command (rc-apps create) was issues, fixes the problem.

Environment

• OS: macOS 10.15.3
• Node: v13.8.0
• NPM: 6.13.7
• @rocket.chat/apps-cli: latest/1.6.0

I don't remember where I found the solution, but for me, I had to run the following command before creating a new app. It installs the needed package.

npm install --save-dev @types/node
