I'm trying to use this gem: csv2json (0.3.0) and I'm getting an error.
On my file essaie.rb:
require 'csv2json'
File.open('essaie.csv', 'r') do |input|
File.open('output.json', 'w') do |output|
CSV2JSON.parse(input, output)
end
end
user@user-ThinkPad-L430:~/development/public/opendata/other$ ruby essaie.rb
/home/user/.rvm/rubies/ruby-2.1.0/lib/ruby/site_ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- orderedhash (LoadError)

When I remove the version 0.3.0(csv2json) and I installed the previous version I'm getting this error:
user@user-ThinkPad-L430:~/development/public/opendata/other$ ruby essaie.rb
/home/user/.rvm/gems/ruby-2.1.0/gems/csv2json-0.2.0/lib/csv2json.rb:17:in `initialize': wrong number of arguments (2 for 0) (ArgumentError)

from essaie.rb:4:in `open'
from essaie.rb:4:in `block in <main>'

any help?
notes : file name essaie.csv contains the same data as input.csv (from the example of the documentation)
Just ran into this myself. Looks like they just forgot a dependency. Gems come with a list of other gems they require, but this developer probably had the orderedhash gem installed already and didn't pay attention to the need for it to be part of the dependency list for csv2json.
I typed:
gem install orderedhash
And then csv2json worked just fine for me.
