env:
win10 / XAMPP using powershell

I think it would be an issue coming from my install process?
Since I can't use the linux one line: npm info eslint-config-airbnb@latest peerDependencies --json | command sed 's/[\{\},]//g ; s/: /@/g' | xargs yarn add --dev eslint-config-airbnb@latest
I had to install separately. As follows:

• yarn add --dev glob@^7.1.1
• yarn add --dev markdownlint@^0.4.0
• yarn add --dev eslint
• yarn add --dev eslint-plugin-jsx-a11y@^5.0.1
• yarn add --dev eslint-plugin-import@^2.2.0
• yarn add --dev eslint-plugin-react@^7.0.1
• yarn add --dev eslint-config-airbnb@latest

Did I miss anything here?
thx

This is because the latest version of eslint (4.0.0) is incompatible with the airbnb and jsx-a11y plugins. I was able to fix it by installing eslint@3.19.0.
So do
yarn remove eslint
then
yarn add --dev eslint@3.19.0

Exactly, let's hope for a fix soon :) In the meantime, stick to 3.19.0!

eslint-config-airbnb still doesn't support ESLint 4 but eslint-config-airbnb-base does. In the next version of the tutorial I'll use it.
