I'm on Ubuntu, and I've done
install gem mongo
which reported
Successfully installed bson-1.0
Successfully installed mongo-1.0
2 gems installed
I've started mongod
Now I cd to the mongo gem directory and try
> ruby examples/simple.rb
and I get the error
./examples/../lib/mongo.rb:31:in `require': no such file to load -- bson (LoadError)
from ./examples/../lib/mongo.rb:31
from examples/simple.rb:3:in `require'
from examples/simple.rb:3
which I can't make sense of, since the bson gem is installed
> gem list
*** LOCAL GEMS ***
bson (1.0)
bson_ext (1.0)
mongo (1.0)
rack (1.1.0)
sinatra (1.0)
Any suggestions what's up here?
The example script doesn't require rubygems, which means that bson isn't going to be in your load path. If you add
require 'rubygems'
to the start of the script, I believe it will work.

I am trying to install Redmine to a Windows Server 2012, following "How to MANUALLY install Redmine 3.x on Windows Server 2008 R2".
After installing http://rubyinstaller.org/downloads/ the next step is to install Bundler but I got the following error:

Any help would be appreciated.
Check your DNS is right.
If your DNS not set, gem will display below error:

Found it! You need to install a loopback adapter on Windows. There's lots of guides on how to do it. One of the first links on DuckDuckGo is that.
After poking around with ruby I noticed that uninstalling and reinstalling ruby does not remove some configs. I found a command:
gem env
This gave me the location of the configuration files. After completely deleting the directory .gem it started to work! Looks like something messed up my gem config and the defaults are right.
Start Command prompt with Ruby
Use command: gem env
Check GEM PATHS and locate directory .gem
Delete .gem directory
Done
Good luck!

I have no experience with ruby. So anyone has a suggestion what I'm doing wrong ?
Thanks in advance

Are you limited to Ruby 1.9.3? Currently the most stable version of Ruby is 2.3.0. Updating Ruby will probably fix this issue.
https://www.ruby-lang.org/en/downloads/
Alternatively, before updating Ruby, check out this thread. Here is a similar error someone had with Ruby 1.9.1. `require': no such file to load -- mkmf (LoadError)
It looks like people on that thread had success using build-essential:
sudo apt-get install build-essential
I am beginner in ruby and wanted to install and GUI toolkit. So i surfed web and found shoes was one toolkit so i downloaded the ".install" file it didn't work saying some permission error, then i downloaded the older version which was ".run" format and that too didn't work so i found a gem of shoes when i try to download i get the below in ruby. i downloaded this shoes from git and still facing some error.

Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all
non-root users on this machine.

the above is the terminal output.

someone help we out with this installation
and if i have done anything wrong in installation of shoes then let me know
From your terminal directory it seems like you are trying to install shoes4 on ruby 1.9.3. To install shoes4 you need JRuby and a JDK - please follow the instructions in the readme
Shoes 3 can't be installed through gem install due to the way it was built. For Shoes 3 you need the install script, I recommend the appropriate Shoes 3.2 version from this page. If this fails with some error please let us know the error so we can help :)
You should use the gem program to install shoes. If on your command line you type gem install shoes you should be fine.
to use it in an app, you would need to create a Gemfile and run Bundle install within your folder
I know I have ruby and gem installed because I've installed a bunch of gems previously. Additionally when I do the following
~$ ruby --version
ruby 1.8.7 (2010-08-16 patchlevel 302 [i486-linux]
~$ gem --version
1.3.7
They, as you can see, return the version--yet when I try to do this--
~$ sass --watch happy.scss:happy.css
bash: sass: command not found
I'm a relative noob to everything, but far more to ruby and gems. For the sake of revealing more or less my level of understanding things generally I've learned enough of Debian to get a an environment where I could get Clojure running and get a web app working (taken me almost a year of spare time to do that--I knew virtually nothing of programming previoiusly). I'm trying to get sass working to ease my mental load in the webpage design side of things and I'm just hitting a brick wall on this.
Would this be a PATH issue? If so what needs to be on the path so that one gem works --
BTW here's what happens when I install sass--
# gem install sass
Successfully installed sass-3.2.5
1 gem installed
Installing ri documentation for sass-3.2.5...
Installing RDoc documentation for sass-3.2.5...
Any help anyone can give will be much appreciated. I've been at this one all day and can't figure it out for the life of me.
justin ⮀ ~ ⮀ gem install sass
Fetching: sass-3.2.5.gem (100%)
Successfully installed sass-3.2.5
1 gem installed
justin ⮀ ~ ⮀ sass -v
Sass 3.2.5 (Media Mark)
seems ok to me. I would check your path.
The proper PATH would depend on where your gems get installed. I use RVM so it will be different. You could try to throw an exception in your ruby code with rubygems loaded this should give you a starting point.

so from that i see /Users/justin/.rvm/gems/ruby-1.9.3-p362#rails3.2/gems/railties-3.2.11/lib/rails/commands/console.rb
so my bin path is at /Users/justin/.rvm/gems/ruby-1.9.3-p362#rails3.2/bin
and if i

so in my case I would want to add /Users/justin/.rvm/gems/ruby-1.9.3-p362#rails3.2/bin
but i use RVM so it does that for me.
Can anyone help with an odd Ruby Gem problem I'm having - note I've installed many gems in the past and never seen this.
I've downloaded the net-ssh and net-sftp gems using the following commands:
sudo gem install net-ssh
sudo gem install net-sftp
both installed successfully. However when I reference the files within my code I get the following error:
./workers/ffmpeg_worker.rb:6:in `require': no such file to load -- net/ssh (LoadError)
from ./workers/ffmpeg_worker.rb:6
from ./workers/tests/test_ffmpeg_worker.rb:3:in `require'

rake aborted!
Command failed with status (1): [/System/Library/Frameworks/Ruby.framework/...]
Note when I do:
gem list --local
The gems are listed as such:
net-scp (1.0.2)
net-sftp (2.0.2, 1.1.0)
net-ssh (2.0.15, 1.1.2)
net-ssh-gateway (1.0.1)
Any clues?
When I see this sort of thing, it usually comes down to having more than one Ruby installed on the machine (which means more than one gem location, etc.), and different apps or environments getting confused about which one to load.
Check for that first. If that isn't the answer, do a gem which net/ssh to see where RubyGems thinks the gem is installed -- make sure it isn't the local user's .gems directory or something.
If neither one solves the mystery, stick some debugging code into your worker script and have it output its load path ($:) so you can see where it's looking.
