[SOLVED] Nub:"meteor mongo" error following tutorial

SOLVED: I didn’t know meteor had to be running to execute the ‘meteor mongo’ command. Discovered that when I tried it all on my main computer and got the message that meteor must be running.

System: xubuntu 18.x on 64bit AMD A8 laptop
Following tutorial and when I got to the subject item I got the following:
pete@4uigL1:~/Documents/Projects/Computer/Software/meteor/simple-todos$ meteor mongo
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
pwd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
chdir: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
mongo: You’re not in a Meteor project directory.

To create a new Meteor project:
meteor create
For example:
meteor create myapp

For more help, see ‘meteor --help’.

As you can see I’m in my project dir, but I’m at a lose why I’m getting this. It seems like some environment variables are missing or not setup up.
‘getcwd’ is not in my system:
pete@4uigL1:~/Documents/Projects/Computer/Software/meteor/simple-todo$ ge
geany genl getent getpcaps
gemtopbm geqn getfacl gettext
gemtopnm getcap getkeycodes gettextize
gencat getconf getopt gettext.sh
genisoimage geteltorito getopts getty

TIA!
