renku init fails on windows 10

[adriente]

Describe the bug I tried to start a renku project locally in an empty folder on windows 10 using the renku init command. The task could not be completed and send me an error message back. Trying again with the --force option throws the same error message.

To Reproduce Steps to reproduce the behavior:

1. run pip install renku
2. Make a new folder
3. Go there using the windows command prompt
4. Type renku init
5. Select 1 Basic python project (and select "print the error" when asked)
6. See the error

Execution output I am sorry, it is messy but it is the most complete information i can provide.
