Those who know at least a little about the Linux subsystem, answer what to do in this situation?

Question

linux

I'm using the Linux subsystem of the Ubuntu terminal. In one course, I installed these packages:

sudo apt-add-repository -y ppa:brightbox/ruby-ng; sudo apt-get update; sudo apt-get -y install curl ruby2.5 ruby2.5-dev gcc make g++ libffi-dev; curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -; sudo apt-get -y install nodejs; sudo gem i jekyll; sudo gem i jekyll-paginate-v2; sudo npm i -g gulp rimraf npm-check-updates bower; sudo chown -R $USER:$(id -gn $USER) /home/$USER/.config

and everything worked fine for me. Now in another project I want to check the package.json packages for updates and I enter the ncu command and I get an error:

Are these packages and modules installed globally in my system or do I need to install some of them again in a new project? Or do I need to update them, if so, how??? Thanks in advance for the replies.

Answer 1

As I understood from the descriptions of the error on these Internets, the verification script fails to resolve the registry.npmjs.org address, DNS does not give it. Try the command again, it will work. If not, write registry.npmjs.org IP address in /etc/hosts. Or for example NS Googl in /etc/resolv.conf.

You are probably talking about WSL. He's too raw for things like this.
Have you tried just adding sudo to the command?
