rbgccxml / rbplusplus gem dependency on hpricot question

Axel Etzold

8/15/2008 2:05:00 PM

Dear all,

I am having problems installing the rbgccxml gem on ubuntu 8.04, I get a runtime error saying that
hpricot version=0.6 is required.
Now I had hpricot installed, as a gem, but it is version 0.6.161 .
Is there any special reason why these two should not work together ?

Thank you very much,

Best regards,

Axel

Sounds like the same problem that rfeedparser has.

The explanation I got was, 0.6.161 is probably fine, but hadn't been tested,
and they didn't want to allow 0.6 or higher, because that would imply a
future 0.7, which might actually break stuff.

In other words, someone very probably didn't know about the gem ~>
specification.

Talk to the author of rbgccxml, and see if they'd be willing to
require "~>0.6" (or would that be "~>0.6.0"?), instead of "=0.6".

The maintainer of rbgccxml is on vacation until next week. Feel free to
contact him after that, and I'm sure he'll give you a speedy response. He's
a good guy: http://github.com/j...

Thanks for pointing this thread out for me Shawn. So many threads come
across when you're gone a week that I usually just mark them as
'read'.

Anyway, rbgccxml is no longer using hpricot. As libxml-ruby has
matured extensively in the past months, I've moved over to that
library. Much faster than hpricot. That said, I will take greater care
in how I define dependencies to hopefully prevent this problem from
happening again.

Further questions about these projects should be posted on the
rubyforge forums page: http://rubyforge.org/forum/?group...
Posting here will send me an email which will allow me to respond quicker.

Hope that helps.

Jason

Dear Jason,

thanks for your response and for your work.
However, I still get this error:

axel@alecrim:~/Desktop$ sudo gem install rbplusplus
ERROR: Error installing rbplusplus:
rbgccxml requires hpricot (= 0.6, runtime)

What should I do ?

Thank you,

Axel
