Hm, this is so strange. Everything seems to be installed correctly.
Could you try to start a project on C:/ please?
Is there something wrong with E: maybe? No space left?
If this doesn’t work, try it the manual way:
- Download https://github.com/driftyco/ionic2-app-base/archive/master.zip and unzip it into a folder
- Download https://github.com/driftyco/ionic2-starter-tabs/archive/master.zip and unzip into the same folder, overwrite files if needed
- Run
npm installin that folder - Run
ionic servein that folder
