I'm receiving the following error when trying to install the holidays gem:
# gem install holidays
Fetching: holidays-1.0.4.gem (100%)
ERROR: Error installing holidays:
holidays requires holidays (>= 0)
I'm not a ruby guy, just installing some deps for Redmine Backlogs plugin.
Versions and environment:
# gem -v
1.8.10
# ruby -v
ruby 1.8.7 (2010-06-23 patchlevel 299) [i386-linux]
CentOS Linux release 6.0 (Final)
# uname -r
2.6.32-71.29.1.el6.i686
The latest version of the gem 1.0.4 seems to require that you have a previous version of the gem so do this and you should be good
gem install holidays --version 1.0.3
gem install holidays
Now you should have the latest version of the holidays gem
UPDATE: The author Alex Dunae has now fixed this problem
