That’s a really old version of npm. My guess is it doesn’t support scoped packages, because it should install @ionic/app-generators, not ionic/app-generators.

Either install node v6, or at least upgrade npm by doing npm install -g npm.

Thank you for your help. I installed node v6 and rebooted. But npm seems
not to be working at all now - it just hangs like this:
[ …] \ fetch: sill doParallel fetch 1

I don’t really know what is going on with it - I’ll probably just give it
up.

Thanks again for your help.

Try running npm cache clean, sometimes it helps. Otherwise, you could try completely removing Node and npm first, then installing the latest version again.

#5

I finally did get it installed - I did npm-windows-upgrade. Not sure if
that’s what did it. But it took a long time to install.
Thanks for your help. I will make a note to try npm cache clean if I run
into more problems.
