stylus nodejs css-parse error

I'm new at Stylus, installed nodejs and stylus and all is ok except when I try to convert a .CSS file to .styl with > "stylus -C filename.css" (also tried with --css) on terminal at file folder, I'm working on kubuntu 14.04 , I'd appreciate any help, oh, I also installed all the libraries I could find with Synaptic for nodejs css-parse or so, the error I get is this:

/usr/lib/node_modules/stylus/node_modules/css-parse/index.js:62 throw err; ^ Error: property missing ':' near line 2:12 at error (/usr/lib/node_modules/stylus/node_modules/css-parse/index.js:57:15) at declaration (/usr/lib/node_modules/stylus/node_modules/css-parse/index.js:189:33) at declarations (/usr/lib/node_modules/stylus/node_modules/css-parse/index.js:219:19) at rule (/usr/lib/node_modules/stylus/node_modules/css-parse/index.js:481:21) at rules (/usr/lib/node_modules/stylus/node_modules/css-parse/index.js:103:56) at stylesheet (/usr/lib/node_modules/stylus/node_modules/css-parse/index.js:73:16) at module.exports (/usr/lib/node_modules/stylus/node_modules/css-parse/index.js:485:10) at new Converter (/usr/lib/node_modules/stylus/lib/convert/css.js:29:15) at Function.module.exports [as convertCSS] (/usr/lib/node_modules/stylus/lib/convert/css.js:16:10)

Look on line 2 of your filename.css file. It's not valid CSS. It's missing a colon. Fix that then retry.
