I'm a beginner, trying to make an app using Ionic-Cordova. When I type "ionic cordova build android", I get this error:
[error] Error: Cannot find module '@angular-devkit/build-angular/src/angular-cli-
files/models/webpack-configs/utils'

I read that the error might be related to the missing node_modules folder, but it's not missing in my project. I've also tried to uninstall-reinstall the Npm, it didn't work either.
Thanks in advance.
