No console output

Hi. Whenever I type in commands and press Enter, nothing happens.

irb(main):006:0> my_hash = { name: "Sean", email: "sean@teamtreehouse.com", favourite_           
numbers: [1, 2, 3]                                                                               
irb(main):007:1> my_hash = { name: "Sean", email: "sean@teamtreehouse.com", favourite_           
numbers: [1, 2, 3] }                                                                             
irb(main):008:1> JSON.dump(my_hash)                                                              
irb(main):009:1> json_output.class                                                               
irb(main):010:1> JSON.parse(json_output)                                                         
irb(main):011:1> JSON.load( File.new("./example.json") )

Is it me or is there a technical issue? Thanks.

You are missing an } at the declaring of the first vairable, so IRB thinks that you are still declaring the first hash

irb(main):006:0> my_hash = { name: "Sean", email: "sean@teamtreehouse.com", favourite_           
numbers: [1, 2, 3]  }                                                                             
irb(main):007:1> my_hash = { name: "Sean", email: "sean@teamtreehouse.com", favourite_           
numbers: [1, 2, 3] }                                                                             
irb(main):008:1> JSON.dump(my_hash)                                                              
irb(main):009:1> json_output.class                                                               
irb(main):010:1> JSON.parse(json_output)                                                         
irb(main):011:1> JSON.load( File.new("./example.json") )

Thanks Daniel. I just looked at my code again and now I see the missing closing brace like you said. You've earned an up vote and Best Answer for your help. :)
