Cannot build on windows

Hi I have some serious issues with ionic…

I have created a small app added ios and android as platforms. I am able to run everything fine on osX, but on windows I am only able to run the application in the browser with:

ng serve

When I try to build android on windows I get errors for each plugin defined in the config file. I have tried multiple windows machines all with the same error.

The errors:

Failed to restore plugin "ionic-plugin-keyboard" from config.xml.

Please help!
