csscss terminates with syntax error

[Boldewyn]

I have no knowledge of Ruby, but csscss terminates on my machine with the following error:

I installed via sudo gem install csscss, and Sass was already there.

Hey @Boldewyn that's because you're running it with ruby v1.8.x. Try installing 1.9.x+ and giving it a shot.

Ruby v1.8.x is at its "end of life" and will sunset soon so it won't receive any new updates (especially security updates).

[Boldewyn]

My Debian uses Ruby 1.9, unfortunately:

$ ruby --version
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

[zmoazeni]

I'm guessing your gem command is using an older version of ruby. You can check this out by running gem environment

Seeing /usr/lib/ruby/gems/1.8/gems/csscss-1.0.0/lib/csscss/cli.rb in your backtrace tips me off to that.

If you run which ruby it should give you a path that includes a different gem command that you can run (the version that is used by 1.9.x).

[Boldewyn]

OK, that was indeed the problem. Somehow I had /usr/local/bin/gem linked to /usr/bin/gem1.8 for whatever reason. Re-installing with the 1.9 gem fixed it. Thanks!

[zmoazeni]

@Boldewyn Awesome. Let me know if you run into any other issues.

[kevboutin]

I have a similar issue.

It will not uninstall it from the 1.8 gem. If I can get it uninstalled from there, then I can use the new gem I already have installed. Unfortunately installing csscss to the new gem will not override the 1.8 version due to the executable being in /usr/bin/.

[kevboutin]

Oh and I used the -i switch to specify ~/.gem location as well but it's not in that location anyway.

[kevboutin]

My problem is not because of the Ruby version. I have 1.9 installed already. I need to get csscss off the 1.8 installation.

$ ruby -version
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin12.3.0]

My problem is not because of the Ruby version. I have 1.9 installed already. I need to get csscss off the 1.8 installation.

gem uninstall csscss should work if that's not working, then it looks like your gem paths are crossed with 1.8 and 1.9.

I recommend gem environment and which gem to help figure that out.

[nilsborg]

@kevboutin @zmoazeni someone asked in another thread how i uninstalled the 1.8 gem and installed the 1.9:

I used the 1.8 bin that ships with Mac OS and since my 1.9 version is used when just typing 'ruby', i called the system ruby with the full path:

sudo /usr/bin/gem uninstall csscss

and after that just install again with your shiny new 1.9 (in my case installed via brew):

gem install csscss

[zmoazeni]

@kevboutin @nilsborchers I'd also recommend looking into rvm, rbenv, or chruby. Installing and dealing with multiple rubies can be a pain and these make it much much easier.

[kevboutin]

Awesome... thanks! I have it working now.
