Hi all, I''m running an application on my localhost, but the command "rails server" behaves very inconsistently. About an hour ago it ran well on another app, but got errors now. According to the errors it seemed that the server began to run but the there is something missing in the library. But I''m very new to Rails so cannot figure out what do these lines mean:

Hi I''m getting the following error : /Users/nikosd/.rvm/rubies/ree-1.8.7-2011.02/bin/ruby -e $stdout.sync=true;$stderr.sync=true;load($0=ARGV.shift) /Users/nikosd/.rvm/gems/ree-1.8.7-2011.02@.../bin/rake test Testing started at 12:00 PM ... (in /Users/nikosd/Work/.../.../...)

If it helps anyone developing Rails, apps, or gems, I wrote a shortcut for set_trace_func, so next time you want to just add a line before and after some function you are trying to debug you can have Ruby temporarily output every line, method, etc. executed. Also, it lets you define the format, use other loggers, etc. via a proc/lambda define, since you might not like the default format.

I''ve searched and search, tried a number of things like unstalling sqlite3 and reinstalling. Reinstalling Rails, building sqlite3 from source, etc. Nothing seems to work. When I try to start up my server I get the following: MacBook-Pro:splash Ross$ rails server /Volumes/Macintosh HD/Users/Ross/rails_projects/splash/json/ruby/1.9.1/gems/sqlite3-1.3.3/lib/sqlite3.rb:6:in

Still fairly new to Ruby and Rails in general and trying to figure out how to address this error. I recently migrated to a new computer and now I get this error message when I try to start the rails server. -bash: /Users/user1/.rvm/gems/ruby-1.9.3-p125/bin/rails: /Users/user/.rvm/rubies/ruby-1.9.3-p125/bin/ruby: bad interpreter: No such file or directory I know what the problem is and

The only complication during the download was that I had to upgrade from version 1.8.6 to

Hi, I''m starting to use Test::Unit to create unit tests for my Rails Applications/Plugins. I don''t have much experience in Ruby Unit Testing. The problem is that the output report is very simple and it is very difficult to discover where is the error. Test::Unit does not show the line number of the error and the Stack Trace printed using the --trace option does not help either.
