I have installed DLTK plugin to my Eclipse, so that I can program Ruby in Eclipse. Then I have installed RSpec. When I try to Run As Ruby Test, I always get the following errors:
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- spec (LoadError)

from /Users/apple/Downloads/eclipse4ruby/configuration/org.eclipse.osgi/bundles/300/1/.cp/testing/dltk-rspec-runner.rb:3:in `<main>'
Dose any additional setup/configuration need on Eclipse to support RSpec?
The error message says that the spec gem cannot be found.
Try:
sudo gem install spec

What must I do when I want to copy an installed gem from one installation to another one without using the gem command?
I have to install SQLite3 on a server without an internet connection. Normally I can do it with a copy of the gem-file:
gem install --local sqlite3-1.4.0.gem --platform ruby
But for SQLite3 it needs a connection to the internet to get libraries to compile some binaries. The installation worked well on a computer with an internet connection.
So my idea was to take my successful installation on the same OS and same Ruby version and copy all the related components, but this did not work.
When I called:
require 'sequel'
db = Sequel.sqlite
I got this error:
LoadError: The specified module could not be found

What is my error?
I'm using Windows Server 2016.
I found a precompiled version of SQLite3 in a GitHub issue which works for me, but I would like to use a newer version.
Use Bundler for this.
In short:
Run gem install bundler on each machine you're using.
Maintain a project Gemfile listing all requirements
Run bundle install when your Gemfile changes and bundle update to update to latest versions. This will generate the Gemfile.lock file.
Prefix ruby execution with bundle exec, e.g. bundle exec ruby myscript or bundle exec rails c
That's a brief summary, but please read up more on Bundler. It's an essential part of modern Ruby deployment.
You need to use the package option of bundler.
First you need to cache your dependencies into vendor/cache with:
bundle package --all --all-platforms
This will install all the dependencies of your Gemfile locally, then add the directory to your source code repository.
When deploying make sure you use bundle install --local to use the local version.
See the documentation for bundle package for more information.

I get this from gem install puppet, gem update, etc. I tried uninstalling and reinstalling libyaml, and same with Ruby. The error happened after I did bundle uninstall puppet to get it to stop pointing to the 6.3.0 gem and point to the 4.10.2 executable. I need Ruby to be able to use Rspec to test the modules. Does anyone know how I can fix this?
Without steps to reproduce the broken system it is hard to say what happened, but I can say in general how you can set this up correctly to use a specific version of Puppet.
Does this help? In the worst case, you can probably uninstall RVM and reinstall it.
Before I continue, let me note that Puppet 4.10.2 and 4.10.3 have both been removed from Rubygems. (Although I was able to install it with PDK.)
For the remainder I assume 4.10.4 instead (just to distinguish it from latest 4.10).
The recommended approach is to use Puppet Development Kit (pdk). If you download and install PDK, you probably just need to do these steps:
pdk convert
rm Gemfile.lock
PUPPET_GEM_VERSION=4.10.4 bundle update # If that version isn't already in PDK.
pdk test unit --puppet-version 4.10.4
If you don't want to go down the PDK path, you can try these alternatives:
Hardcode the version of Puppet you want in Gemfile.
gem 'puppet', '4.10.4'
Or:
gem 'puppet', '~> 4.10' # latest 4.10
Then update your bundle:
rm -f Gemfile.lock
bundle update
Or, you can implement the PUPPET_GEM_VERSION feature by adding this code (this is what I do, for what it's worth):
if puppetversion = ENV['PUPPET_GEM_VERSION']
gem 'puppet', puppetversion
else
gem 'puppet'
end
And then:
rm -f Gemfile.lock
PUPPET_GEM_VERSION='~> 4.10' bundle update
Now you can run your unit tests against a specific version of Puppet per normal:
bundle exec rake spec
Or however you set it up.
I am trying to run a ruby file from jenkins shell.

cd /home/user/Desktop/Rubyfolder
ruby test.rb

Please help. Thanks in advance.
It looks like Jenkins isn't loading the RVM environment where your Gem is installed. Check out RVM's instructions on integrating it. There's also a plugin that might be helpful.
The summary steps are:
Make sure RVM is installed for the jenkins user
Run source "$HOME/.rvm/scripts/rvm" from jenkins .bashrc
Add rvm use ruby_version[#gemset] in your setup script
Or use rvm rubyversion[#gemset] do <command>
I can't figure out why my RSPEC isn't working. I reinstalled RSPEC with sudo gem install rspec and then tried again to install with a specific version number (sudo gem install rspec -v 2.11.0)
I continue to get the following error message and I cannot figure out what it means. I believe that I may or may not have version 1 also installed, not sure.

I'm working on some cucumber tests from The Cucumber Book. I've got the code that tries to use a transaction processor and there is a file with the following code:
require 'service_manager'

The service_manager gem is installed in /opt/local/lib/ruby1.9/gems/1.9.1/gems as are other gems that the application uses. Until I added the code for this iteration, there were no problems. I've looked for reasons why the gem is not found and just can't figure out why. Any help would be appreciated.
It appears to be a load path issue.
Is require "rubygems" invoked prior to this require statement?
Also, if you're using bundler, you have to add this gem to your Gemfile, as bundler attempts to sandbox your dependencies. If you're using bundler, try the following after adding the gem to the Gemfile:
bundle exec rake cucumber
