Npm touble on cloud 9: dev environment and login

Hi every body. I am just starting the back end curriclum. I created my account and I just installed npm, the lattest version. When i logged in back, I can’t get anymore the progress message with “COMPLETED” and i think i am right as i get all the answer from the tutorial here “”;
secondly when i arrived at the oudated and update part, i did’nt get any message with the commands 'npm oudated mypackage".
Could some explain what is going on? Thank you for you insight !!
