Phython error when trying to start new Ionic project

I have recently updated the Ionic CLI, and now when I try to start a new project I get the following error…

	D:\dev>ionic start viewportTest

	? What starter would you like to use: blank
	√ Creating directory .\viewportTest - done!
	√ Downloading and extracting blank starter - done!

	? Would you like to integrate your new app with Cordova to target native iOS and Android? Yes
	√ Personalizing ionic.config.json and package.json - done!
	> ionic integrations enable cordova --quiet
	√ Downloading integration cordova - done!
	√ Copying integrations files to project - done!
	[OK] Added cordova integration!

	Installing dependencies may take several minutes.

This is on a WIndows 10 machines, and I have set the PYTHON env variable, which it is actually finding (ie my Python IS at C:\Program Files\Python36\python.exe"


Anyone have any ideas?

Thanks in advance


maybe the connection got no response in time. Maybe you should try it later again or look what is slowing down your connection.

Best regards, anna-liebt

What do you know, I tried it again (after a break), and it now works! Never thought it was anything to do with connectivity.

Thanks heaps for that!
