sinatra app on localhost via unicorn: syntax error

I have a Sinatra app that I continually upgrade (local only, at the moment). Problem being that I know nothing at all about Ruby — my friend made me the app and it's worked beautifully for over almost a year.

To see the site on localhost, I do this: 

bundle exec unicorn -l 9000

I don't understand this, haven't needed to. I know I'm using the unicorn gem to run the app directed at port 9000 (due to an old printer conflict).

Today, I get this error: 

in `evaluate': compile error (SyntaxError)
syntax error, unexpected ':', expecting $end

which refers to line 16 of my gem file, the sinatra-contrib gem:

gem "sinatra-contrib", require: "sinatra/reloader"

I've never had this error before. Haven't ever touched the gem file, and it's been working for a year. The only thing I can think I've done recently that may have affected my environment is installing a gemset called Wordless:

rvm use 1.8.7@wordless --create --default && gem install therubyracer sprockets compass coffee-script thor yui-compressor && rvm wrapper 1.8.7@wordless wordless compass ruby

I'd appreciate insights, and hopefully I can start to learn a thing or two about managing ruby gems. Thanks.

You were using Ruby 1.9 before. The line you referenced is in 1.9 format, which Ruby 1.8 does not understand.

When you installed Wordless you said:

rvm use 1.8.7@wordless --create --default

This made Ruby 1.8.7 your default interpreter. To switch back to whatever you used before do:

rvm list rubies

And then:

rvm use [the 1.9.x you found in the list above] --default
