Describe the bug

The bug happens when trying to compile the website with Hugo locally.

After installing Hugo using the instructions on the wowchemy documentation and downloading a template from its repository in .zip format, the following error happens when using the command hugo or hugo server:

Indeed, it was already answered here !

I'm really sorry that I didn't picked it up in my first search through the existing issues. I'll be more careful next time.
