Invalid gemspec

[sramsay]

Love, love, love earthquake. But can't run it anymore, because I get:

Invalid gemspec in [/usr/lib64/ruby/gems/1.9.1/specifications/earthquake-0.8.1.gemspec]: Illformed requirement ["#Syck::DefaultKey:0x0000000251a278 0.4.3"]

when I try to install it.

In fact, that error appears even when earthquake is not actually installed (when running anything having to do with gems, irb etc.)

Any thoughts on what might be causing this? Is there a way to clear out the gemspec and start over?

It seems the problem of old version rubygems.
Please try gem update --system and reinstall earthquake.

Best regards.

Thanks for the quick response!

Unfortunately, "gem update --system" yields:

"Latest version currently installed. Aborting" (and repeats the invalid gemspec errors).

Hmm...
I will check it.
But right now, my sleeping time is coming :)

Anyone have any thoughts on this? Just can't get rid of it . . .

Manually edit /usr/lib64/ruby/gems/1.9.1/specifications/earthquake-0.8.1.gemspec

1. Find the lines content #Syck::DefaultKey:0x0000000251a278 0.4.3
2. Replace #Syck::DefaultKey:0x0000000251a278 0.4.3 with ~> 0.4.3

I don't think this is a smart way, but it worked for me.

Doesn't work for me. In fact, no amount of screwing around with that file does anything (including erasing it).

Can someone at least explain the nature of the problem? I'm not familiar enough with rubygems to really be able to figure out why it's failing. I haven't been able to use earthquake in months.

possible workaround:
export RUBYOPT=-rpsych
(note that you need ruby installed with libyaml.)

[sramsay]

Finally! That seems to have fixed it. Thank you so much, irohiroki (and everyone who replied).

But, um, what did I just do? ;)

[irohiroki]

well, ruby has two yaml engines, syck (legacy) and psych (brand new).
the default is syck which I don't know why (maybe the problem of dependency?) and to use psych, you need to require it.
that's it :)

Great!!!
