Windows Universal App: Build error on Windows 10 Pro 10.0.14393


Hi all

I have two questions related to WUP and Ionic 2.

1 - I have created a Project for testing using tabs template:
ionic start wup tabs --v2
ionic platform add windows
ionic build windows

After that there is a build error:

How to fix this?

2 - I have created a Project in Visual Studio 2015 Community Edition for Windows Universal App using Ionic 2 tabs template. Then the app ran successfully in the Windows 10 emulator.
I can use the app however tab buttons are not displayed properly at the bottom in the emulator.
Is this a Ionic 2 issue? (See image below)

Thanks in advance

Best regards,


First issue. Try removing your node_modules folder and then npm install from your directory again
Second issue. I have the same problem, but apparently it’s an emulator issue. Once you’re on actual hardware, that doesn’t happen.


Thank you very much for your answers.

About first one I have tried what you said but I did not work.

So I removed node v0.12.2 (installed by VS 2015 CE) and then installed node v4.6.1 from Node website and I could build successfully.
