Regarding Ruby on rails in windows 7. after installing the railsinstaller, I am facing lot of issue and not sure what the cause is?

PS: I posted this question on stack-overflow, somewhere else while looking for answer of similar issue, where a gentleman suggest me to put my question on separate thread. And here it goes.

The windows 7 is behind proxy and websense. I run all applications as administrator. I wonder if I left any site/blog for the issues I am facing. Though it is my first question here on ROR in stack-overflow after I exhausted options of reading and searching to resolve it.

I am even not able to do the

$ gem install rubygems-update

though I the path is correct and showing

c:\>gem sources

display

http://rubygems.org.

as the only source.

I am still getting the below error for the even simple database creation. That was given in root directory of sample rails project namely SampleROR.
Any help please.

$ rake db:create
The i18n gem is not available. Please add it to your Gemfile and run bundle install
rake aborted!
cannot load such file -- i18n
c:/RailsInstaller/DevKit/home/anil-ku/SampleROR/config/application.rb:3:in `require'

c:/RailsInstaller/DevKit/home/anil-ku/SampleROR/Rakefile:5:in `<top (required)>'
(See full trace by running task with --trace)

Note that I am not able to do

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems>gem update --system
ERROR:  While executing gem ... (Zlib::GzipFile::Error)
    not in gzip format

with latest version of rails, installed using railsinstaller one click for windows.
I did the bundle install after this, that run successfully but the issue didn’t disappear.

It shows i18n installed. Not sure what is the issue.

$ rails --version
Rails 3.2.1

also, downloading gem package and run it using ruby setup.rb also didn’t work

C:\RailsInstaller\rubygems>ruby setup.rb

C:\RailsInstaller\rubygems>

My gem version is

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems>gem -v
1.8.16

I tried to download gem manually from site (from http://rubygems.org/gems/) and installed few of them. So able to install some while for most other gems it give error like below

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems>gem install mongrel

Finally my environment details for gem is

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems>gem env
RubyGems Environment:

  - REMOTE SOURCES:
     - http://rubygems.org/

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems>

I note that there is nothing like ruby folder under
C:/Users/anil-ku/.gem/ruby/1.9.1
the only thing under the above one is a folder named specs that looks irrelevant.

Also the path environment is windows is

C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems>echo %PATH%
C:\RailsInstaller\Ruby1.9.3\bin;C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\bin;C:\RailsInstaller\DevKit\bin;C:\RailsInstaller\Git\c

m32\WindowsPowerShell\v1.0\;;C:\Program Files\cvsnt;C:\Program Files\TortoiseSVN\bin;d:\RailsInstaller\Git\cmd;d:\RailsInstaller\Ruby1.9
.3\bin

Any help for how to proceed for simple database connection with above and/or how to install gem fully?

You need to set your proxy settings for rubygems. For example set the Environment Variable like so:
