ruby_threadptr_data_type error

I am new to Ruby / Rails, and having issues getting my environment setup on Ubuntu 12.04. I'm using rbenv (not rvm). Here is how i'm installing ruby:

# clone rbenv and the ruby-build plugin
git clone git://github.com/sstephenson/rbenv.git .rbenv
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build

# initialize rbenv
export PATH=~/.rbenv/bin:$PATH
rbenv init -

# install ruby 1.9.2
rbenv install 1.9.2-p320
rbenv rehash

# change ruby version to 1.9.2
rbenv global 1.9.2-p320

I am trying to run the following hello-world app: https://github.com/renderedtext/base-app

I am running the commands recommended on the website

bundle install
bundle exec rake db:setup db:test:prepare
bundle exec rake spec
bundle exec rake cucumber

It fails at bundle exec rake spec with the following error:

NOTICE:  CREATE TABLE will create implicit sequence "roles_id_seq" for serial column "roles.id"
NOTICE:  CREATE TABLE / PRIMARY KEY will create implicit index "roles_pkey" for table "roles"
NOTICE:  CREATE TABLE will create implicit sequence "users_id_seq" for serial column "users.id"

If you have it installed as a ruby gem, then you need to either require

It is also important to note that the server seems to already have ruby 1.9.1 installed (presumably using apt-get) but I would like to use 1.9.2 which is why I installed rbenv.

As a side note, I've also tried using rbenv with 1.9.3 and get the same error.

I tried to research and apply answers from other stack overflow questions (like ruby_threadptr_data_type error) but resulted in a segfault. Also, in my research most of the answers seemed to relate to rvm and 1.9.3 ... not rbenv and 1.9.2

Please help!

  • so that actually did the trick ... but now it has me wondering -- that project is forked by a 16 people ... is this issue specific to linux? or is the project just broken for everyone? Commented Nov 6, 2012 at 22:29
  • ruby-debug is outdated, I believe that using debugger is a better solution in a long run. Commented Nov 7, 2012 at 13:46

It seems like rspec couldn't load ruby-debug. Here's where it's happening if you're curious. You probably forgot to add require 'rubygems' in your spec_helper.rb. Do so and let me know if this fixed it.

UPDATE:

Try removing gem 'ruby-debug19' from Gemfile and replacing it with gem 'debugger' then run bundle in console and try again. ruby-debug19 is not maintained so this probably the cause. More about debugger. There's also link to ruby-debug19 installation instructions(if you feeling lucky).

He is using Ruby 1.9x so require rubygems is not needed.
hey Vadim, the specfile has requite 'rubygems': github.com/renderedtext/base-app/blob/master/spec/…
