Versions:

I already did npm cache clean and npm install -g yo/yeoman-generator/generator-generator. Already reinstaled node and npm.

Thanks for your time :)

Answer 1

You need to update yo to the latest version.

npm -g update yo

And if that doesn't work, then you want:

npm -g uninstall yo
npm -g install yo

Answer 2

I had similar issue. However, updating or re-installing yo didn't help me.

My node environment is managed by nvm, where I am currently using node v6.2.0. However, yo was installed long ago in my pc while I was using node v4.4.1. When I used v4.4.1, I didnt get the error.

So, conclusion is that the yo angular-fullstack commands are working in the same node version in which it was installed. As nvm is handy in switching between node version, its not a big deal for me. I use v4.4.1 only when i generate some angular components, and switch back to the latest version.
