I have an installation of ruby 1.9.1
ruby 1.9.1p378 (2010-01-10 revision 26273) [i386-mingw32]

any suggestions would be appreciated.
thanks.
The problem is not in ActiveSupport. It appears in the stack trace simply because it overrides the builtin Kernel#require method.
The file "Cms3/tools/rake/tasks.rb" has require 'ftools' on line 4, but ftools is deprecated in Ruby 1.9. Modify these tasks to use fileutils instead and you'll be good to go.

I know this type of question is already asked.
I use s3 gem to upload my files in s3 bucket. But after s3 gem installation, when I start rails server it shows this error:

Does anyone know, how to solve this error? Should I try another gem?
Yeah i just ran into this issue and resolved. It is because AWS updated their gem to 2.0. If you update the gem to 2.0 different configuration is required according to this article they posted.
If you want to using the version you had before, just change the Gemfile like below:
Gemfile
gem 'aws-sdk', '< 2.0'
We had the same issue this morning. We already had this aws-sdk gem installed but it was updated to version 2 yesterday. It seems that version 2 doesn't fix this anymore so I advice to use last version 1 : 1.61.0
I'm new to ruby, rails and mysql.
My operating system is Ubuntu 13.04, the version of ruby is 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux] and the version of rails is 3.2.13.
When I executed this command: rake db:migrate --trace, I encountered such errors:

It's quite weird, and I don't know how to handle it. Any ideas?
The gem called date_time_precision is conflicting with active support.
From the date_time_precision docs:
Gem Compatibility
Sometimes other gems will use the Date/Time class in ways that don't preserve precision. If you want to use the DateTimePrecision gem with these gems, any compatibility issues will most likely need to be patched within DateTimePrecision itself. This is because DateTimePrecision makes some modifications to how the core Date/Time classes work. (For example, by allowing nil values to be passed to constructors.)
This gem should work with Rails/ActiveSupport 2, 3, and 4 (but perhaps missing some edge cases).
So far, the following gems are on the compatibility watch list:
[.] ActiveSupport
[x] Virtus
[x] Coercible
[ ] Chronic
[ ] Timeliness
[ ] Timecop
[ ] delocalize
You should remove this gem if you are not confident in fixing it yourself.
Using Ruby 2.0 x64 on Windows. Installed sqlite3 gem by downloading the sqlite3 autoconf sources and compiling. Then I did a gem install sqlite3 --platform=ruby .... However, now when I run rails server, I get the following error. Where is this sqlite3_native.rb? I can't find it anywhere.

Here is a tutorial for installing SQLite3 with Ruby 2.0 on Windows.
It is rather a complicated process. Follow the tutorial and see if it works after that.
I have a rails 3.0.20 app running with rvm on ruby 1.9.3p327. My Gemfile reads:
gem 'image_science', :git => 'git://github.com/asynchrony/image_science.git'
and Gemfile.lock has its version as:
remote: git://github.com/asynchrony/image_science.git
revision: dc36ddaadc46aecdef907de3c41a9d14d28ba8d8
specs:
image_science (1.3.2.1.Asynchrony)
I cannot seem to start my app without removing image_science, since I keep getting this error:
/home/umar/gems/ruby/1.9.1/gems/activesupport-3.0.20/lib/active_support/dependencies.rb:242:in `block in require': iconv will be deprecated in the future, use String#encode instead.

How can I fix this error.
You may need to install the required libraries (FreeImage and RubyInline) to make ImageScience work. (ImageScience RDoc)
By the way, I assume that you don't use mini_magick or rmagick because you don't have access to an imagemagick or graphicsmagick installation.
Perhaps you should try to use one of these two, because ImageScience has not been updated for a while.
Hope this helps.
I have a production instance of our application in AWS EC2. My team develops locally on Fedora 18. Recently, when pushing our code to production, we noticed that we were getting segmentation faults when running'rake assets:precompile' or 'script/delayed_job start|stop'. These work fine on our development machines.
In attempts to isolate the problem, we upgraded RBENV from 1.9.3-p327 to RBENV 1.9.3-p385. Then, to try and isolate RBENV, I created a new user, 'testuser', and a clean install of RVM with 1.9.3-p385. Same problems.
The segfault detail seems to point to 'therubyracer' gem. I can not find any information that looks like our problem.
