pygments_ext not found #7

serialhex · 2011-09-12T00:10:47Z

hi, when i try to run bench.rb i get this:

serialhex@mobilhex [~/.rvm/gems/ruby-1.9.2-p290/gems/pygments.rb-0.2.1]$ ruby bench.rb                                                                          [ruby-1.9.2-p290] 
/home/serialhex/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': no such file to load -- pygments_ext (LoadError)

        from bench.rb:14:in `<main>'

i manually looked for the file and there is none. from what i understand this uses embedded python, so i shouldn't need python installed (though it is). just so you know, i'm running archlinux & rvm with ruby 1.9.2 if you need any other information let me know

The C extension is not included with the gem. You can only use the FFI interface.

hmm, ok, well commenting out Pygments::C.highlight(code, :lexer => 'ruby'), in bench.rb gives me this:

yes, a fun set of debugging this is going to be :P any ideas?

Weird. Can you try using the library instead of running the benchmark? Either bundle install && rake to run the tests, or simply ruby -e' require "pygments"; puts Pygments.highlight("1+2", :lexer => "ruby")'

serialhex · 2011-09-12T12:19:46Z

same thing:

i was trying to get octopress syntax highlighting working & i boiled it down to this... :-/ i'm not sure what the deal is

tmm1 · 2011-09-12T21:31:55Z

What linux distro is this on?

tmm1 · 2011-09-12T21:34:20Z

Sounds like this line is failing: https://github.com/halostatue/rubypython/blob/master/lib/rubypython/pythonexec.rb#L16

Can you try doing that via irb or similar? %x(python -c "print 123")

serialhex · 2011-09-12T21:37:03Z

32bit archlinux... and i keep it pretty up to date also. i take it there is probably some fun library that might have broken backwards-compatibility on the near-bleeding-edge of things? ahh the joys of being fully up-to-date :P

serialhex · 2011-09-12T21:40:52Z

ahh, i think i see:

justin@act-linux [~/src/tmp]$ pry                                                                                                                                                                                                                           [ruby-1.9.2-p290] 
pry(main)> %x(python -c "print 123")
  File "<string>", line 1
    print 123
            ^
SyntaxError: invalid syntax
=> ""
pry(main)> %x(python2 -c "print 123")
=> "123\n"

python 2.x is named python2 in archlinux... python is python 3.x ... so maybe get the version string & if it's not <3 then try python2 (i think it's named that on gentoo systems too) and see if that works...?

tmm1 · 2011-09-12T22:02:33Z

require 'pygments'
RubyPython.configure :python_exe => 'python2'
puts Pygments.highlight(File.read(__FILE__), :lexer => 'ruby')

serialhex · 2011-09-12T22:14:26Z

hmm... sticking that into a file and running it gives me:

so that's not it :(

I'm a arch user as well, I've managed to fix my problem by doing:

RubyPython.configure :python_exe => 'python2.7'

Hope this helps :]

Gonzih · 2011-09-21T09:30:55Z

@ngty Thanks man! It's works now!

serialhex · 2011-09-22T15:27:28Z

@ngty i just tried this, and it works beautifully!!! thank you!

nkoehring · 2012-05-08T06:17:24Z

Strange, I'm sticking to the same problem as @serialhex before and now I'm stuck. Like before I got the issue with finding the correct python exe. After fixing it I still get the missing lib.so error.

I test this with

ruby -e' require "pygments"; RubyPython.configure :python_exe => "python2.7"; puts Pygments.highlight("1+2", :lexer => "ruby")'

UPDATE

I found out that the missing lib.so thing comes due a nil in the list of libraries to load. It happens in /ffi-1.0.11/lib/ffi/library.rb so it seems to be an problem of the FFI gem.
