Subject [jira] [Commented] (DTACLOUD-420) Mock: Exception is thrown when creating a new instance
Date Thu, 24 Jan 2013 10:47:13 GMT

    [ https://issues.apache.org/jira/browse/DTACLOUD-420?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13561552#comment-13561552
] 

Christian Karnath commented on DTACLOUD-420:
--------------------------------------------

>> ruby --version
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]

>> curl -k -X POST -F "name=newNewInstance" -F "hwp_id=m1-small" -F "image_id=img1"
--user "un:pw" "localhost:3001/api/instances?
format=json"
{"code":500,"message":"undefined method `write' for #<Syck::Emitter:0x0000000396bba0>","error":"NoMethodError"}

After setting the following RUBYOPT environment variable as a workaround, everything works
fine:
RUBYOPT='-rpsych' bundle install

It seems to be a ruby 1.9.2 related issue with YAML parsing:
