For any question like this, you really need to post the output of ionic info.

We have exactly the same problem. Does somebody have an idea? Thx!!

These are our ionic logs:

√ Creating directory .\ionbavo2 - done!
√ Downloading and extracting tabs starter - done!

? Would you like to integrate your new app with Cordova to target native iOS and Android? No
√ Personalizing ionic.config.json and package.json - done!

Installing dependencies may take several minutes.

It’s hard for me not to type a snarky comment here, but I’ll try my best. As I said earlier in the thread, if you want help with this, you need to provide the output of ionic info.

Node-sass isn’t compatible with Node 9. Use the current Node LTS.


#7

Thank you so much. I uninstalled nodejs version 9 and installed LTS. Ionic is now running. Because I spent some much time and also realized there many people with the same problem, I will enter a link in stackover flow to direct users here.
