Bundler ignores groups in rails apps - ruby-on-rails-3

This problem was fixed in 0.9.8, but seems to have recurred in the 1.x branch.
In my Gemfile I have a group for the test and development environments that use the rspec gems.
On my production server rspec is not installed.
I used the command bundle install --without test development in my
rails app
Starting my rails app in production mode gives the exception:
Could not find gem 'rspec (>= 0)' in any of the gem sources listed in
your Gemfile.
If I comment out the test group the same error happens with the development group.
The same problem exists if I start in development mode, then it tries to load the gems in the test group.
It seems that bundler completely ignores the environment groups and tries to load all gems in Gemfile:
group :test do
gem "rspec"
end
group :development do
gem "rspec-rails"
end
versions:
bundle 1.0.15
rails 3.0.7
ruby 1.9.2-p180

I was having this problem too, the problem was that .bundle/config file had something like
"--without development test"
even tho I had never ran the bundle command with this parameters(maybe I cloned the repository from the Webbynode server and their system added this automatically for production...)
anyway, the fix was
rm .bundle/config
bundle install

gem not working after installing 'thin' - rails 3.2.8

I got stuck in a dead end after trying to install the gem 'thin' on the environment
RHEL 6.0
Ruby 1.9.3
Rails 3.2.8
As indicated, I added
gem 'thin'
to my Gemfile and ran
bundle install
The installation seemed to be successful, but after that, whenever I run 'gem', I get
<internal:prelude>:8:in `lock': ERROR: Failed to build gem native extension. (Gem::Ext::BuildError)
ERROR: Failed to build gem native extension.

While if I run again 'bundle install' I get
Unfortunately, a fatal error has occurred. Please see the Bundler troubleshooting documentation at
http://bit.ly/bundler-issues. Thanks!

I even tried to follow troubleshooting at https://github.com/bundler/bundler/blob/master/ISSUES.md but nothing has changed.
Looks like there's something corrupted in the eventmachine gem installation, but I can't neither uninstall or reinstall it.
Has anybody got an idea?
I would like at least to be able to revert to the (working) configuration prior to thin installation....

An error occurred while installing pg (0.12.2), and Bundler cannot continue

I'm following the Michael Hartl Ruby on Rails Tutorial & there is a part where he is he he instructs you to update your Gemfile to include:
group :production do
gem 'pg', '0.12.2'
end
And then enter the below commands in your terminal:
bundle update
bundle install --without production
When you run the bundle update command it throws back the below errors.

Make sure that `gem install pg -v '0.12.2'` succeeds before bundling.
sample_app:$
I was able to overcome this error easily be removing the 'pg', '0.12.2' gem from the Gemfile & replacing it after running the bundle update command. This seems to work fine as the 'pg', '0.12.2' gem is aslo omitted in the without production flag in the latter bundle install --without production.
The 'pg', '0.12.2' gem is only needed for deploying to heroku with the correct database & everything works fine even when I deployed it to heroku but I'm just wondering if this is an error in the Tutorial or am I missing something bigger here?
It's also annoying to have to remove this Gem everytime I run bundle update, is bundle update really that necessary?
Thanks in Advance
I'm following the same tutorial and I think it's redundant to run update without modifying existing dependency, but in this case it's even causing problems because update command has not --without argument.
I stumbled upon Rails 3 cheatsheet which mentions bundler workflow this way:
After adding or removing dependencies from Gemfile
$ bundle
Commit Gemfile and Gemfile.lock
After modifying existing dependency versions
$ bundle update
Commit Gemfile and Gemfile.lock
I read man pages for bundle update and tried RECOMMENDED WORKFLOW which consists of running bundle update after bundle install.
In my case (some output omitted):
$ bundle install --without production
Resolving dependencies...
Using rake (10.0.3)
...
Installing rspec-core (2.11.1)
Your bundle is complete!
Gems in the group production were not installed. <-- check
$ bundle update
Resolving dependencies...
Using rake (10.0.3)
...
Using uglifier (1.2.3)
Your bundle is updated!
Gems in the group production were not installed. <-- check
I tried it with new RVM gem set and everything was installed correctly.
After that Gemfile.lock contains pg (0.12.2) and deploying to Heroku works.
RECOMMENDED WORKFLOW
In general, when working with an application managed with bundler, you
should use the following workflow:
After you create your Gemfile for the first time, run
$ bundle install
Check the resulting Gemfile.lock into version control
$ git add Gemfile.lock
When checking out this repository on another development machine, run
$ bundle install
When checking out this repository on a deployment machine, run
$ bundle install --deployment
After changing the Gemfile to reflect a new or update dependency,
run
$ bundle install
Make sure to check the updated Gemfile.lock into version control
$ git add Gemfile.lock
If bundle install reports a conflict, manually update the specific
gems that you changed in the Gemfile
$ bundle update rails thin
If you want to update all the gems to the latest possible versions
that still match the gems listed in the Gemfile, run
$ bundle update
Installation of postgres fails with this error : "Can't find the 'libpq-fe.h header"
Looks like a lot of people faced this problem, good news is : stackoverflow has the answer ;)
Can't find the 'libpq-fe.h header when trying to install pg gem
(or at least it should help you to look in the right direction)

ruby on rails server is not running

i m new to ruby on rails can any one help me. i cant start my rails server below is the error which m getting

Getting Rails working with a JS runtime environment

I'm using Ubuntu 11.10 and the terminal to install and run Rails. Here
is the process I've taken so far to setup Rails:
download and install Ruby 1.9.2 and Rails 3.1.0
-- I did this using sudo apt-get ruby1.9.1 and sudo gem install
rails
I made a new rails app using rails new path/to/app
I went to the new app directory and tried running rails server and got an
error about not having a JS ruby environment
I had to get a JS runtime environment for execjs so I downloaded 'therubyracer'
as well as 'therubyrhino' and added them to my gem file, one at a time like this:
gem
'therubyracer' then ran bundle install
After everything was successful with the install, I ran rails server again
-- with both runtime environments I have had similar errors:
Could not find libv8-3.3.10.4 in any of the sources
Run `bundle install` to install missing gems.
Could not find therubyrhino-1.73.0 in any of the sources
Run `bundle install` to install missing gems.
Bundle knows where these programs live, giving correct pathnames when I
enter bundle show libv8 or bundle show therubyrhino. They are both
in /usr/lib/ruby/gems/1.9.1/gems/_ where all the other gems are
located for the bundle install.
Does anyone know where this exception is coming up in the Rails source
code? Does anyone know how Rails is gathering the gems? Better yet,
anyone had this problem and know how to fix it?
Thanks so much,
Feav
Have you tried starting the server using bundle exec rails server?
This problem has been fixed in a newer version of Rails.

Heroku error when launch rails3.1 app missing postgres gem

I am trying to deploy to heroku.
Rails 3.1.0.rc4,
I get the following error from Heroku logs:
Starting process with command: `thin -p 48902 -e production -R /home/heroku_rack/heroku.ru start`
2011-06-20T11:25:44+00:00 app[web.1]: /app/.bundle/gems/ruby/1.9.1/gems/activerecord-3.1.0.rc4/lib/active_record/connection_adapters/abstract/connection_specification.rb:71:in `rescue in establish_connection': Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.) (RuntimeError)
I tried to install the activerecord-postgresql-adapter but then I get this error:
Could not find gem 'activerecord-postgresql-adapter (>= 0)' in any of the gem sources listed in your Gemfile.
So I tried to add this to my gem file
gem 'pg'
which produced this error:
Installing pg (0.11.0) with native extensions /Users/imac/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:533:in `rescue in block in build_extensions': ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)
any ideas?
You don't have to install Postgres locally. In your Gemfile, put 'pg' in group :production, as johnny-grass suggests, and then when you run bundle, just specify --without production, like this:
bundle --without production
Unfortunately, you have to remember this argument when you run bundler, but at least you don't have to install and maintain postgres locally.
Please note that Heroku "strongly recommends against" using sqlite, saying that "Your production and development environment should be as close to identical as possible" http://devcenter.heroku.com/articles/rails3
Do you have PostgreSQL installed on your computer? If you don't then install it first, then install the pg gem.
# gemfile
group :production do
gem 'therubyracer-heroku', '0.8.1.pre3' # you will need this too
gem 'pg'
end
I found a solution in this Heroku article.
As Jared said, they suggest to create a different group for postgresql.
