Ruby on Rails: Can anyone identify what would possibly cause this error when running a rake?

Question

Does anyone have any idea what would cause this error when running a rake?:

Answer 1

Use the new gem "debugger" instead of ruby-debug19, fixes ruby-debug for ruby 1.9 and had its own linecache , lives here https://github.com/cldwalker/debugger

Answer 2

It seems to me that you happen to use the quick fix for the ruby-debug19 which in fact use a custom gem source, more specifically this source 'https://gems.gemfury.com/8n1rdTK8pezvcsyVmmgJ/' in your Gemfile.

If you do, then you probably bump into the same issue I have here, that is a all gems installed from this source, for example linecache19 or pg-0.13.2-x86_64-darwin-11 are statically linked to library of user barry (probably the author). I did not much have success with custom source gems so I uninstall all of them and do it the hard way that is to grab the linecache gem from the sourceforge site.

Answer 3

Check your syntax in your database.yml file and make sure your aren't missing a variable or constant assignments there or in your initializes. I've had obscure rake errors with these causes.

Answer 4

So I ran into a similar error trying to run 'bundle exec rspec spec' on my machine after installing mongodb with macports for my ruby application.

bash-3.2$ bundle exec rspec spec

**Notice: C extension not loaded. This is required for optimum MongoDB Ruby driver performance. You can install the extension as follows: gem install bson_ext

If you continue to receive this message after installing, make sure that the bson_ext gem is in your load path and that the bson_ext and mongo gems are of the same version.

I can't say for sure if this will work for you but what I found was that the macports instillation of mongo somehow messed up my gem files and after installing mongo with brew and uninstalling and manually deleting the gem folders with the -x86_64-darwin-11... extension on them I could run my rspec and cucumber tests with a mongod server running.

This is my first post on Stack Overflow I hope this may help!
