Using rbenv and Rails 4.2.6, when I run bundle exec rails s or bundle exec rails c, I see the following:
Ignoring sqlite3-1.3.11 because its extensions are not built. Try: gem pristine sqlite3 --version 1.3.11
That's all, nothing else happens. If I then stop spring, and run bundle exec rails c, the following appears:
Ignoring sqlite3-1.3.11 because its extensions are not built. Try: gem pristine sqlite3 --version 1.3.11
Ignoring sqlite3-1.3.11 because its extensions are not built. Try: gem pristine sqlite3 --version 1.3.11

The problem is debug_inspector gem, you could try to remove web-console gem in your Gemfile, bundle install, and run the server again.
UPDATE:
Or if you would like to keep the web-console gem, you could try to remove all the gems you have installed, and re-bundle install them again. According to this issue on rails/web-console.

Gem::LoadError: Specified 'postgresql' for database adapter, but the gem is not loaded. Add `gem 'pg'` to your Gemfile (and ensure its version is at the minimum required by ActiveRecord).
ETCETCETC
Note how it randomly deletes the 'pg' gem after initial bundling. Could someone point me in the right direction?
Set your pg gem to require version 0.2x in your Gemfile:
gem 'pg', '~> 0.20'
What's happening is you're system is incorrectly attempting to use a newer, incompatible version of pg. pg 1.0.0 was released January 10, 2018, but it's not currently supported by rails. Since you aren't specifying which version of pg to use, you're system is trying to use the new version of pg, removing the old version, then failing.
See this rails issue, and this rails issue and this fix (Revert to pg 0.21.0 as Rails does not support pg 1.0.0 yet) for more discussion.
Put your pg gem out of development environment.
Remove gem pg from developement
group :development do
# Access an IRB console on exception pages or by using <%= console %> anywhere in the code
gem 'web-console', '>= 3.3.0'
gem 'listen', '>= 3.0.5', '< 3.2'
# Spring speeds up development by keeping your application running in the background
gem 'spring'
gem 'spring-watcher-listen', '~> 2.0.0'
end
and keep it outside from developement
# Postgres for active record
gem 'pg'
Try to the following
Remove gem 'pg' from group :development and keep that on Gemfile outside of group, then run bundler bundle update then follow these steps
git add .
git commit -m "Fixed gem pg issue"
git push heroku master
That will work
If you little bit confused again see the Heroku documentation and start from scratch
Thanks
I am trying to replicate the Advanced testing setup from Michael Hartl's Rails Tutorial, which uses guard-minitest.
Here is my Gemfile:
source 'https://rubygems.org'
gem 'rails', '4.2.2'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
group :development, :test do
gem 'sqlite3', '1.3.10'
gem 'byebug', '6.0.2'
gem 'web-console', '2.2.1'
gem 'spring', '1.3.6'
end
group :test do
gem 'minitest-reporters', '1.0.20'
gem 'mini_backtrace', '0.1.3'
gem 'guard-minitest', '2.4.4'
end
group :production do
gem 'pg', '0.18.2'
gem 'rails_12factor', '0.0.3'
end
And here is what I get when I run bundle install --without production:

Bundle updated!
Gems in the group production were not installed.
So, it seems I do have guard-minitest 2.4.4 installed.
However, when I run bundle exec guard init, I get the following error:
/Users/XXX/.rvm/gems/ruby-2.2.1#global/gems/bundler-1.10.4/lib/bundler/rubygems_integration.rb:292:in `block in replace_gem': guard is not part of the bundle. Add it to Gemfile. (Gem::LoadError)

from /Users/XXX/.rvm/gems/ruby-2.2.1/bin/ruby_executable_hooks:15:in `eval'
from /Users/XXX/.rvm/gems/ruby-2.2.1/bin/ruby_executable_hooks:15:in `<main>'
Any idea of what I am doing wrong?
As specified in the install section of the guard-minitest README, with newer versions of the gem, guard is also required.
I just updated my Gemfile as follows:
[...]
group :test do
gem 'minitest-reporters', '1.0.20'
gem 'mini_backtrace', '0.1.3'
gem 'guard'
gem 'guard-minitest', '2.4.4'
end
[...]
and now everything is working just fine.
I am trying to learn how to do testing with Rspec, Capybara & Guard. This requires me to install wdm gem as well to work with guard listener on windows.
For some reason its failing.
Can someone tell me what is happening here? This is a bit out of my league. The wdm gem for some reason is not installing:

Make sure that `gem install wdm -v '0.1.0'` succeeds before bundling.
Make sure you have installed Devkit,if you did not,downloads DevKit, Then Click Extract and wait until the process is finished.Next, you need to initialize the DevKit and bind it to your Ruby installation. Open your favorite command line tool and navigate to the folder you extracted the DevKit into.Auto-detect Ruby installations and add them to a configuration file for the next step.
ruby dk.rb init
Install the DevKit, binding it to your Ruby installation.
ruby dk.rb install
run
gem install wdm -v '0.1.0'
bundle install
bundle update
If you get error just check which gem needs to be installed and install it.But I would recommend RailsInstaller.
Note: RailsInstaller is the best package for installing rails on windows.I have tried it on windows8 works great.It includes all required Packages. RilasInstaller - http://railsinstaller.org/en
I was using a cloud9 ide online but I had to install gem rmagick. But the ide did not let me to do and gave an error. So I decided to download my project in to my local area. Then when I try to bundle install, it throws and error for therubyracer.
I though Osx has its own way to handle java part. So if i take out gem rubyracer from gem file, bundle install works fine. But then when i say rails server, i get an error;
rails server

I had a similar problem installing Rails on a Rapsberry Pi because therubyracer has no package for arm processors.
It can be solved installing node.js which you can download here: https://nodejs.org/download/
After you installed it you can remove therubyracer from your Gemfile and run bundle again. After you did that everything should be fine...
// You also need to add this line to your Gemfile:
gem 'execjs'
Then run bundler again.
Its described here: http://ajacevedo.com/2013/using-node-js-as-a-rails-javascript-runtime/
// IN your case the Less Gem requires therubyracer not rails itself. So its a gem specific problem. It has been discribed here: https://github.com/seyhunak/twitter-bootstrap-rails/issues/336

Anyways, removed both gems, 'therubyracer' and 'less-rails-bootstrap'. Now using 'bootstrap-sass'.
