I'm trying to compile a very simple less file which simply includes Bootstrap:
/* application.less: The most awesomely complicated file in the whole world. */
@import "bootstrap/bootstrap.less";
I'm on an Ubuntu 12.04 derivative and I've tried using the lessc compiler found in the node-less package:
$ sudo apt-get install node-less
...done!
$ ( cd /path/of/less/file/ && lessc application.less )
TypeError: Cannot call method 'charAt' of undefined

Not easily deterred, I then tried using the Ruby version of lessc.
$ sudo apt-get remove --purge node-less
$ sudo gem install less
...done!

Come on! Ruby doesn't know how to manage dependencies?! Whatever. Fine.

The Ruby Racer requires libv8 ~> 3.11.8
to be present on your system in order to compile
and link, but it could not be found.
In order to resolve this, you will either need to manually
install an appropriate libv8 and make sure that this
build process can find it. If you install it into the
standard system path, then it should just be picked up
automatically. Otherwise, you'll have to pass some extra
flags to the build process as a hint.
If you don't want to bother with all that, there is a
rubygem that will do all this for you. You can add
following line to your Gemfile:
gem 'libv8', '~> 3.11.8'
We hope that helps, and we apologize, but now we have
to push the eject button on this install.
thanks,
The Mgmt.
And I'm done. Is there any easy way to get a working less compiler installed on my distribution? This is getting ridiculous.
