Updated gems. Sup now crashes with an error about "undefined method 'yaml_tag'

I'm guessing this is something to do with a new ruby version and yaml/psych, but I can't be much more helpful than that unless someone else knows what to look for.

Weird... yaml_tag is part of psych which is part of ruby's stdlib since 1.9.3, and it should be loaded at that moment...

Out of curiosity (don't know if it's going to help a lot), could you please run these ?

$ ruby --version
$ ruby -e 'require "psych"; puts Object::yaml_tag "blah"'

joe@Joe-Arch-20150109 ~ % ruby --version                                                           :(
ruby 2.2.1p85 (2015-02-26 revision 49769) [x86_64-linux]


joe@Joe-Arch-20150109 ~ % ruby -e 'require "psych"; puts Object::yaml_tag "blah"'
blah

As a side note, renaming my entire .gem folder and re-downloading sup with all its dependencies (making sure to download xapian-ruby first before sup) fixed it.

I'm copying over each gem folder one at a time to see if I can isolate the problem any further.

Is it possible that you installed "psych" via rubygems? I had similar problems and removing the gem version of "psych" fixed this for me.

Thanks, this worked perfectly!

I'm still curious though why installing psych would break sup, since
psych is included in ruby by default, right?

It probably just breaks psych, which sup depends on.

Why not close this issue? 😄
