Had same weird issues with Node js Version: 9.3.0.
My Solution was to downgrade to an older Version. In my Case im Using 7.0.0 now.
If you wonder how you can downgrade on Windows. Go to Programs and Features and uninstall it like any other Program (DONT USE THE NODE UINSTALLER). After that restart your PC and Node should be deleted and then you can download the 7.0.0. Version here (go for the msi file): https://nodejs.org/download/release/v7.0.0/
