raburton,
Sorry that you are seeing issues with angular project creation.
1. Are you on Windows? If yes, then which version of Windows?
2. Do you see the same problem if you select ‘Use System Installation’ option for Node.js and NPM in the project creation wizard?
3. Do you have git bash or any other shell installed on your Windows system ?
4. If you already have git bash installed, then a possible quick resolution, you could either uninstall the system git-bash or temporarily rename a folder on the path to git-bash and try to create a project. This time, git-bash and the appropriate node and npm versions will be downloaded to your .webclipse folder (off your home directory) and executed from there. You should then be able to rename the system git folder back to what it was.
Apologies for inconvenience caused.
