Issue while setting up a blank app


#1

when I use the command ionic start todo blank is downloads some stuff and starts installing until at some point this error appears:

 Running command - failed!

it seams to be about the file win32-x64-57_binding.node which doesn’t exist on github servers…

Do any of you experience similar errors… is something broken on github or did I do something wrong?

While installing I stricktly followed the tutorial at:
http://ionicframework.com/docs/v1/guide/installation.html

As discussed multiple times here in the forum in the last few hours and days Ionic is not ready for npm8 yet. Try it with an older version and it will work.
