Error with starting App on Ionic


#1

OS: Windows10 (x64)
Node js Version: 9.3.0
Ionic Version:3.19.0

I followed guideline on Ionic homepage step by step.
But the error occurs when I try to start new Ionic Apps.
I repeated deleting and re-installing so many times, but same result.
what am I supposed to do?

These are commands that I entered.

npm install -g cordova ionic

ionic start myApp tabs

And These are errors after that.

× Running command - failed!

Had same weird issues with Node js Version: 9.3.0.
My Solution was to downgrade to an older Version. In my Case im Using 7.0.0 now.
If you wonder how you can downgrade on Windows. Go to Programs and Features and uninstall it like any other Program (DONT USE THE NODE UINSTALLER). After that restart your PC and Node should be deleted and then you can download the 7.0.0. Version here (go for the msi file): https://nodejs.org/download/release/v7.0.0/


I have installed (Ionic ,java,cordova,Node js,android SDK all install) on window 10. than project created time error

Oh, I really appreciate it…!

I stayed all night because of this problem…

I wonder why the latest version doesn’t work at all.

Anyway, thanks again!
