Iconv will be deprecated in the future - ruby

I tried to read an excel file using this code:
require 'rubygems'
require 'parseexcel'
workbook=Spreadsheet::ParseExcel.parse("D:/TEST.xls")
and I faced the following error:
C:/Ruby193/lib/ruby/site_ruby/1.9.1/rubygems/custom_require.rb:36:in `require': iconv will be deprecated in the future, use String#encode instead. default formats are encoded in ISO-8859-1

from C:/Ruby193/lib/ruby/gems/1.9.1/gems/parseexcel-0.5.2/lib/parseexcel/parseexcel.rb:10:in `parse'
from lkc.rb:4:in `<main>'
What is the problem, and why can't I read the excel file?

I think the actual error message is this, on the second line:
No such file or directory - D:/TEST.xls (Errno::ENOENT)
Try D:\TEST.xls or D:\\TEST.xls instead.

The title is misleading, this "Iconv will be deprecated in the future" is not the real issue - it's just a warning. As #brandon-tilley says, the problem is that the file you are trying to open does not exist. Try opening IRB, and typing File.open("D:\Test.xml") etc until you do not get an error message. Then you know the file exists and the path is correct, and you can continue debugging other aspects (if there are still errors).

You have to run your project from the MINGW 64-bit command prompt. Not from the regular DOS prompt (Windows Command Prompt).
Make sure you follow the instructions here:
http://www.ruby2d.com/learn/windows/
Note the last paragraph:
Using Ruby 2D on Windows
When working with Ruby 2D, make sure to use a MinGW 64-bit command prompt, rather than a standard one (cmd.exe) or the “Start Command Prompt with Ruby” found in the Start menu.
Fixed this issue by creating usr/local/bin folders in the C/users/username directory
and pasted the dlls required which can ne found on Link for dll
extract it and copy the dll from bin and paste in the new bin directory that you have created .
Imp- usr/local/bin was my default dll-load directory i hope its the same for others too but please check the error message properly.

'Learn Ruby on Rails' tutorial: Can't submit contact form

I am getting the error below following the tutorial in the book Learn Ruby on Rails.
I am able to launch my app manually by typing the URL into my browser but am wondering why Heroku open does not work.
Any idea what is happening here?
Heroku open error...

The short answer is that Heroku uses Launchy to launch my app and Launchy is looking for my browser. Since I am using Nitrous.io, I do not have a browser installed, so Launchy does not know what to do.
The author of Launchy explains that "...launching a browser from within the virtual box would do nothing if there was no browser installed." https://github.com/copiousfreetime/launchy/issues/78
Launching manually appears to be my only option at this point.

Migrating Tumblr to octopress (Jekyll) - in wrong directory

I'm trying to migrate a blog from Tumblr to Octopress.
When I run in the octopress directory
ruby -rubygems -e 'require "jekyll/migrators/tumblr"; Jekyll::Tumblr.process("http://example.org", format="md")'
It starts running but then complains about what folder it's in
/usr/lib/ruby/gems/1.9.1/gems/jekyll-0.11.2/lib/jekyll/convertible.rb:27:in `read': No such file or directory - /usr/lib/ruby/gems/1.9.1/gems/jekyll-0.11.2/lib/jekyll/migrators/../_posts/tumblr/2012-08-28-how-to-add-your-picture-to-google-results.md (Errno::ENOENT)

from -e:1:in `<main>'
Here's a quick and dirty fix that worked for me (doesn't apply if you don't have root access, obviously), but it will get the job done.
Here's your error message for reference:
/usr/lib/ruby/gems/1.9.1/gems/jekyll-0.11.2/lib/jekyll/convertible.rb:27:in `read': \
No such file or directory - \
/usr/lib/ruby/gems/1.9.1/gems/jekyll0.11.2/lib/jekyll/migrators/../_posts/tumblr/2012-08-28-how-to-add-your-picture-to-google-results.md (Errno::ENOENT)
The full path in the exception is:
/usr/lib/ruby/gems/1.9.1/gems/jekyll0.11.2/lib/jekyll/migrators/../_posts/tumblr/2012-08-28-how-to-add-your-picture-to-google-results.md
Here's the solution:
1. cd to /usr/lib/ruby/gems/1.9.1/gems/jekyll0.11.2/lib/jekyll/migrators/
2. cd ..
3. ln -s %{DIRECTORY_WHERE__posts_LIVES}
4. Re-run your migration command
Just creating this symlink fixes the issue but it's an obvious and total hack.
Does the file /usr/lib/ruby/gems/1.9.1/gems/jekyll-0.11.2/lib/jekyll/_posts/tumblr/2012-08-28-how-to-add-your-picture-to-google-results.md exist? If not maybe you could just move your posts to that folder first, just as a simply workaround.

Fix for unreadable ghostscript font

I'm using the ruby Scruffy gem to create some graphs. It relies on RMagick to render the text and create the pngs. When I run my ruby script I get this error.
sh: gs: command not found
sh: gs: command not found

You need to install ghostscript (see: gs: command not found). How you do this depends on what platform you are on.

Ruby Rspec outputs literal escape characters on windows

I'm following the ruby on rails tutorial: http://railstutorial.org/chapters/static-pages#top
I'm up to using rspec. Having installed the win32console gem, it outputs gibberish in the console, i assume it is outputting the ansi colour change codes:
>rspec spec/
?[31mF?[0m?[31mF?[0m
Finished in 0.34376 seconds
?[31m2 examples, 2 failures?[0m

Any tips how to fix this?
Ansicon works a treat!
http://adoxa.110mb.com/ansicon/index.html
Download, extract it somewhere, and do:
ansicon -i
Then close/reopen the command prompt. Sweet!
There was a bug in beta releases of RSpec 2. If you upgrade to latest you should now see colors if you have win32console installed.
See this: http://github.com/rspec/rspec-core/issuesearch?state=closed&q=color#issue/143
UPDATE: Keep an eye on this thread:
http://groups.google.com/group/rubyinstaller/browse_thread/thread/2d2a62db7281509a/?pli=1
Update:
Rspec is still very buggy with windows coloring, especially if you're trying to use it with Autotest and/or Spork.
If you are still seeing escape codes, a quick hack is to edit the following file (exact path will depend on your version of RSpec)
%RUBY_HOME%\lib\ruby\gems\1.9.1\gems\rspec-core-2.0.1\bin\rspec
And add the following line
require 'win32console'
