I tried to install Yarn and when I used the yarn
command I got:
00h00m00s 0/0: : ERROR: There are no scenarios; must have at least one.
my yarn --version
is 0.32
. Why doesn't it work?

It looks like that I was trying to execute the wrong yarn, because simply running sudo apt install yarn
on my Ubuntu 18.04 gave me yarn from cmdtest.
So I solved by uninstalling it:
sudo apt remove yarn
And by installing it as the official website explains, which in my case (Ubuntu 18.04) it was the following:
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee
/etc/apt/sources.list.d/yarn.list
sudo apt update && sudo apt install yarn

You've got the wrong yarn. The yarn you're executing comes from the cmdtest
package. Uninstalling cmdtest first should fix this:
sudo apt remove cmdtest
Once you've uninstalled it, run the commands below to install yarn properly:
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt update
sudo apt install yarn
