Script is not compiling

[tkepler]

I am getting an error after installing CoffeeScript, Jade and Stylus.

ty@ty-ThinkPad-T60:~/btproof$ sudo ./build.sh Building to build/... mkdir: cannot create directory ‘build//lib’: File exists Building HTML with locals: { "order_server": "https://www.btproof.site/", "contact": "[email protected]" }
