After upgrading to Rails 4.2, I was excited to try out the newly integrated web-console, but I'm having some issues.
In the release notes for Rails 4.2, it mentions: "New applications generated with Rails 4.2 now come with the Web Console gem by default."
Since I upgraded to 4.2, I assume that means I will still have to specify it in my Gemfile. Without adding it to my Gemfile, rails just gives me "undefined local variable or method `console'" so I assume that to be the case.
Once I added gem 'web-console', '~> 2.0' to the Gemfile, and run rails server, I now get:

I googled around and didnt find much. Any advice is greatly appreciated.
Thanks!
It turned out that my issue was coming from the dependency 'debug_inspector'.
Thanks to this: https://github.com/banister/binding_of_caller/issues/39
I just had to run:
$ gem uninstall debug_inspector
$ bundle install

I'm using Rails 5.0.1. I want to run a background process, independent of my Rails server. I thought the workling plugin would helhp me out -- https://github.com/ascarter/workling . However, upon adding this Gem to my Gemfile
gem 'workling'
and restarting my server, I get this error
Gem Load Error is: uninitialized constant ActiveSupport::CoreExtensions
Backtrace for gem load error is:

The last commit in workling repo you posted was on Jun 2008. The one RubyGems is using is from February 2009. Either way, R.I.P and there is no point trying to make it work with Rails 5 app :( I strongly recommend checking younger and actively maintained gems, like sidekiq, resque, delayed_job or many others.
I have just started learning Ruby on Rails. I installed all the related softwares and started exploring the same. When I try to start the default server in Rails (WEBrick), I am getting the following error.

Upon research in SOF, found from the link and other link that the nokogiri needs to be updated in the Gemfile. I updated and executed the Bundle Install command. Even after that, its not working. Please suggest me the ways to fix it. FYI, I am using the latest versions of gems.
I also updated my Gemfile with
gem 'rack', '~> 1.6.0'
It did not work.
Install an older version of rails (4.0.0) because I think windows doesn't have stable version of rails > 4.0.
Change the version in gemfile.
A few days ago I updated my gems because things weren't running so fine, so I went back to 1.4.2. Since then I'm getting all kind of weird errors.
I'm using Ruby 2.0.0p247, Rails 4.0 and Ubuntu.
If I try to start a new app using rails new eraseme, everything goes fine until it's time to do bundle install. The output is:

Have you already installed bundler? If not, try:
gem install bundler
If so, try:
gem install bundler --pre
If you running Ruby version manager, what version are you running? You might be set to the wrong version of Ruby.
I think it would be easier for you if you used RVM or some other version manager.
if you have multiple versions of rubygems installed, uninstall all but the one you want to use.
I think rails 4 requires rubygems 2.x.
Also check the bundler version.

I have tried installing the latest version of the gem:

And looking inside:
D:\Ruby\Ruby200\lib\ruby\gems\2.0.0\gems\tiny_tds-0.6.0.rc1-x86-mingw32\lib\tiny_tds
I can see there is no 2.0 directory, which leads me to believe version 2.0 isn't supported. However i can see no mention on the TinyTDS github or any other sites about this issue.
So, am i missing something or does TinyTDS currently just not work with Ruby 2.0?
Copying the answer from the comments in order to remove this question from the "Unanswered" filter:
I believe this is an issue with OS that you are using as another
individual had the same issue. As stated I believe this is a
dependency issue with Windows. Please see the comment from MetaSkills

I am using Rails 3.2.9 with ruby 1.9.3 (made default using RVM). From the root directory of my test_app when I executed the command 'rails console' / 'rails c', the following error is showing.

Can anyone help me to resolve this?
Yes, I got the answer for my question.
Just Open the file 'Gemfile' inside the root directory of your application folder, and then paste the below lines there.
gem 'execjs'
gem 'libv8'
gem 'therubyracer'
After pasting it, just save the file and execute 'bundle update' on the command prompt.
On finishing bundle update successfully, you try running 'rails c' or 'rails console' for taking the rails console. It works!!
Thank you.
Install the folowing both:
gem 'execjs'
gem 'therubyracer'
Try installing
gem 'therubyracer'
