Ruby / Cucumber - "poses" causing problems
We recently installed a copy of our structure on a different machine and for some reason we get an error when using 'puts' instead of 'Kernel.puts' (we are using Ruby)
This is not a huge problem, but we sometimes use "puts" to write the cucumber results to the file.
It only happens on one machine and not on the other. Both are mac minis, same specs.
Both machines have the same gemlist, the same Ruby version, etc. (both were installed almost at the same time).
Has anyone else seen this?

Something, somewhere, is overriding yours puts
. You just need to find it. Alternatively use warn
. From Avdi Grimm Exceptional Ruby:
puts, however, something desired as a method of reporting failure. Since its output goes to $ stdout, which is buffered by default, the output cannot be printed right away, or it might exit in an amazing order
warn is more concise, but uses $ stderr as the output stream. Also note that warning output can be temporarily disabled by passing the -W0 flag to Ruby.
