请求指导
那个mysql2的我知道怎么解决 但是之前那个错误怎么解决

/home/bluemark/.rvm/gems/ruby-2.2.0/gems/activesupport-3.2.19/lib/active_support/values/time_zone.rb:270: warning: circular argument reference - now
rake aborted!

Answer 1

circular argument reference - now

这个要检查你的代码，而且 backtrack 里边已经给出出错的地方是

/usr/local/redmine/app/models/issue_relation.rb:73:in `<class:IssueRelation>'
/usr/local/redmine/app/models/issue_relation.rb:18:in `<top (required)>'

可能是变量有反复引用自身的情况。可以贴下代码上来吗
