ruby - File contains data in an unknown format (Runtime Error) -

i'm trying build , run ruby code team fellow member wrote class project.

this error i'm getting:

ps c:\users\bryan\team6\planetdefense> ruby main.rb c:/ruby192/lib/ruby/gems/1.9.1/gems/gosu-0.7.41-x86-mingw32/lib/gosu/patches.rb:36:in 'initialize': file contains info in unknown format. (runtimeerror) c:/ruby192/lib/ruby/gems/1.9.1/gems/gosu-0.7.41-x86-mingw32/lib/gosu/patches.rb:36:in `initialize' c:/users/bryan/team6/planetdefense/classes/playstate.rb:9:in `new' c:/users/bryan/team6/planetdefense/classes/playstate.rb:9:in `initialize' c:/ruby192/lib/ruby/gems/1.9.1/gems/chingu-0.8.1/lib/chingu/game_state_manager.rb:300:in `new' c:/ruby192/lib/ruby/gems/1.9.1/gems/chingu-0.8.1/lib/chingu/game_state_manager.rb:300:in `game_state_instance' c:/ruby192/lib/ruby/gems/1.9.1/gems/chingu-0.8.1/lib/chingu/game_state_manager.rb:148:in `push_game_state' c:/ruby192/lib/ruby/gems/1.9.1/gems/chingu-0.8.1/lib/chingu/helpers/game_state.rb:37:in `push_game_state' main.rb:22:in `initialize' main.rb:56:in `new' main.rb:56:in `<main>'`

this appears offending code:

class gosu::song alias initialize_ initialize def initialize(*args) args.shift if args.first.is_a? gosu::window initialize_(*args) end end

any ideas on "data in unknown format" is? i've googled , can't come anything? help.

i found "data in unknown format" related mp3 file gosu trying play. commenting out code related resolved error.

it's best not utilize .mp3s in gosu right now, .wav improve choice

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
