Hello. I'm doing tutorials from mdbootstrap.com and I stopped on chapter "Gulp & Customization" from Responsive Web Design because of some issues. I can't install Gulp properly. I did everything step by step like in tutorial, but it doesn't work. When I type npm install gulp -g into Git Bash, It shows me less then half of text, that It was in tutorial video, and a warning, I think. Then if I click on my gulp pro package, choose "Git bash here" and type first npm init, then npm --save-dev gulp it shows me just Sorry, name can only contain URL-friendly characters., but I think it's chain reaction. I tried on other laptop with Windows 8.1, I reinstalled it but It didn't work. What should I do? I attach screens from Git Bash, that contains process of installation and initialization.
