Hi,
Sorry for my bad english :)
I formatted my PC and reinstalled WIN8 32 bit.
Before guard works correclty and i can compile sass, livereload my page, concat and minify js but now livereload doesn't work any more :(
thats a screenshot

I installed ruby via rubyinstaller 1.9.3-p448 ,
guard(gem install guard),
guard-compass(gem install guard-compass),
guard-livereload(gem install guard-livereload),
guard-uglify(gem install guard-uglify),
guard-concat(gem install guard-concat)

what i have to do ?
thanks

You can either use Guard with polling

$ guard -p

or install the wdm gem

$ gem install wdm

preferably by by putting it into a Gemfile,

thanks it works now with guard -p

I had the same problem. I add gem 'wdm', '~> 0.1.0' into the Gemfile and the problem was solved. Thank @netzpirat for your post.
