Unable to run tugboat after installing

[ghost]

On a Digital Ocean Ubuntu 12.04 x64 droplet, I get a syntax error when running tugboat. Ruby is 1.8.7, gem is 1.8.15, tugboat is 0.2.0.

The error is: syntax error, unexpected ':', expecting kEND (SyntaxError).

More information below.

1.8.7 only supports the hashrocket syntax.

Can you upgrade your version of ruby to 1.9+?

I upgraded to 1.9.1 after removing all the vestiges I could find of 1.8.x. I get a different error message now. My apologies--I am not a Ruby programmer so this is harder for me to troubleshoot.

I have tugboat 0.0.9 running on a different droplet, but I'm not sure how to get that version. When I installed it, I'm pretty sure I just used "gem install tugboat" to that a month or so ago.

@DHancock If you only installed the ruby1.9.1 package you will need to install ruby1.9.1-dev too. You can also install the ruby1.9.3 package from the start as it should take care of everything.

Excellent! I installed Ruby 1.9.3, ran "gem install tugboat" and all is well now. Many thanks!

Glad it worked out!
