Is there also a jruby version of the concurrent gem?
Because, when I do:
leon@polly:~$ gem install concurrent
I get this error message:
Building native extensions. This could take a while…
extconf.rb:1:in `require’: no such file to load – mkmf (LoadError)
from extconf.rb:1
ERROR: Error installing concurrent-0.2.2.gem:
ERROR: Failed to build gem native extension.
I saw the 0.2.1 version had a jruby specific gem, but not 0.2.2
Thanks!
