Answer 1

This issue is caused by not having nodejs installed or by having an out of date version of nodejs.

When I had this issue I found out I was running node v.10.19.0, I upgraded to 15.6.0 and now it works.

I’m running Ubuntu 20.04, if you are too try the following commands:

sudo apt update
curl -sL https://deb.nodesource.com/setup_15.x | sudo bash -
sudo apt-get install -y nodejs
node -v
