| RESOLVED: | |
| The problem was that a JSON parser needs to be provided. | |
| RTFM ... | |
| https://github.com/jnunemaker/twitter#readme | |
| says: | |
| Help! I'm getting: "Did not recognize your engine specification. | |
| Please specify either a symbol or a class. (RuntimeError)" | |
| If you're using the JSON request format (i.e., the default), | |
| you'll need to explicitly require a JSON library. We recommend yajl-ruby. | |
| So the resolution then becomes: | |
| $ rvm use 1.8.7@t | |
| $ gem install twitter yajl-ruby | |
| $ ruby -e'require "twitter";require"yajl";puts Twitter.user("peter_v").location' | |
