[EMRJ]

When I run bundle exec rubycas-server -c config.yml got the following error

=> Using custom config file "config.yml"

I'm having the same problem, any work-arounds?

thanks

This is a duplicate of #242, the problem is one of the dependencies doesn't support Ruby 2.2. If you downgrade to Ruby 2.1.5 it will work fine.

[jordinl]

@lucaspiller how is this a solution?

[HectorOrdonez]

I am going through a lot of pain right now.

[ribanez7]

I have this problem solved locally; will merge my code and send a PR as soon as possible during this month.

[Skill-Zozo]

so much pain

[pikitgb]

Any solution for this ? Downgrading the ruby version solves the issue ?

[HectorOrdonez]

@pikitgb Yes. Using ruby "1.9.3" fixed THIS problem. Then I had others.
I recommend, if possible, running away from this. Installing CASino atm.

[pikitgb]

@HectorOrdonez thanks! I figure that out 45 mins ago lol. I'm checking CASino. is working ok until now.. besides therubyracer and libv8 headache. Thanks.

The only problem is on the use of the R18n gem. If you replace all the R18n related lines with the I18n library it works perfectly with all newest ruby versions.
Still haven't got the time to do so on the repo...

still got this problem under ruby 2.2.4
