Below is my environment:

GitLab 7.7.1
GitLab Shell 2.4.1
GitLab API v3
Ruby 2.2.0p0
Rails 4.1.1

This is probably because of ruby 2.2.0. Gitlab doesn't support that ruby version yet. Supported version is 2.1.5.

Yes, this is a ruby 2.2 issue.

Status changed to closed

ok. changing ruby version back to 2.1.x. Thanks!

mentioned in issue #3130 (closed)
