Starting server fails....union: can't convert Array into String (TypeError)

[webandy]

Hello. I installed taps on my Ubuntu 8.04 slice hoping to move the db schema + data to a local copy. I am unable to start the server. I installed the latest version of taps and an older version of taps I needed to get working on my local Mac with Heroku (which happened to be version 0.2.26).

Here is what the older version install looked like: sudo gem install taps -v 0.2.26 --no-rdoc --no-ri Successfully installed thor-0.9.9 Successfully installed rest-client-1.3.1 Successfully installed sequel-3.0.0 Successfully installed taps-0.2.26

If I uninstall that and get the latest: $ sudo gem install taps Successfully installed taps-0.3.11

I have the following versions of rack and sinatra if that makes a difference? rack (1.2.1...) sinatra (1.0...)

$ taps server "mysql://localhost/mydb?user=user&password=pwd" foo bar123 /usr/lib/ruby/gems/1.8/gems/rack-1.2.1/lib/rack/utils.rb:138:in union': can't convert Array into String (TypeError) from /usr/lib/ruby/gems/1.8/gems/rack-1.2.1/lib/rack/utils.rb:138 from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:ingem_original_require' from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in require' from /usr/lib/ruby/gems/1.8/gems/rack-1.2.1/lib/rack/request.rb:1 from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:ingem_original_require' from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:in require' from /usr/lib/ruby/gems/1.8/gems/rack-1.2.1/lib/rack/showexceptions.rb:3 from /usr/local/lib/site_ruby/1.8/rubygems/custom_require.rb:31:ingem_original_require' ... 14 levels... from /usr/lib/ruby/gems/1.8/gems/thor-0.9.9/lib/thor.rb:78:in start' from /usr/lib/ruby/gems/1.8/gems/taps-0.2.26/bin/taps:13 from /usr/bin/taps:19:inload' from /usr/bin/taps:19

I'm referencing this blog post: http://adam.heroku.com/past/2009/2/11/taps_for_easy_database_transfers/

Anything else I can try?

can you try uninstalling rack 1.2.1 and installing rack 1.1.0 and see if it works?

I just updated the Ruby on the machine since it was 1.8.6 and thought it might be a 1.8.6 vs. 1.8.7 issue perhaps (just a guess) $ ruby -v ruby 1.8.7 (2010-06-23 patchlevel 299) [x86_64-linux] Same issue though unfortunately.

Yah! Removing rack-1.2.1 and install rack 1.1.0 fixed the issue. Thanks for the speedy response!

I'm having the same issue. Unfortunately rack 1.2 is required by another library I've got installed. Couldn't taps just load the right version by itself?
