If you have installed nodejs from your package repo in ubuntu it is called nodejs and not node. You can solve it whit a symlink creation:
ln -s /usr/bin/nodejs /usr/local/bin/node
- Error: "TypeError: this is not a typed array" or "TypeError: path must be a string"
Check your node version, and upgrade it if under 8.0.0
e.g. install node 8._ in Ubuntu:
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
