(installing RPi Blynk client) -g command doesn't work

Hi everyone

I’m new to Blynk and raspberry pi.So I was following the instructions on the blynk site and all commands worked fine except the commands with -g ( like sudo apt-get install -g npm ).
It says that de g command not understandable is in combination with another one , and I really dont know how to fix this.
Thanks in advance

take the -g out

sudo apt-get install npm

This worked .
Thank you very much :slight_smile:
