I always get this error message when I run \"Ionic start project name\":
Running command - failed![ERROR] An error occurred while run
In my case it was $NODE_PATH missing:
NODE="/home/ubuntu/local/node" #here your user account after home
NODE_PATH="/usr/local/lib/node_modules"
PATH="$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:$NODE/bin:$NODE/lib/node_modules"
To check just echo $NODE_PATH
empty means it is not set. Add them to .bashrc is recommended.
