I've updated an old ionic application. After the update I get the following error:

Error: Node Sass does not yet support your current environment: Windows 64-bit with Unsupported runtime (67)

I've googled and searched for the answer. But nothing helps. I've tried to delete de node_modules directory, also reinstalling node sass. Also downgrading.

NPM version: 6.4.1

Node: v11.1.0



npm ls node-sass

[ERROR] ionic-app-scripts has unexpectedly closed (exit code 1).



        The Ionic CLI will exit. Please check any output above for error         details.

Can anyone help me?

Edit:

It looks like it was an mismatching version numbers. After the change I got another error. Does anyone can help me with this?
