I develop a package called CodeRunner that has a number of add-on package (CodeRunner modules, all with names like ...crmod). One of these is called trinitycrmod.
On Debian stable (wheezy), I have installed RVM using the standard instructions. My .bashrc is setup correctly: the final line is:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
I am using Ruby 2.1.0 (but this error can be reproduced with 1.9.3)
rvm use 2.1
I have installed CodeRunner and trinitycrmod:
gem install coderunner
gem install trinitycrmod
Now the CodeRunner gem contains the tool coderunner. One of coderunner's commands is called ex, and it evaluates the ruby fragment you give the command. I want to load trinitycrmod.
coderunner ex ' require "trinitycrmod"'
But I get an error when loading the file (which is part of the installed gem).
.rvm/gems/ruby-2.1.0/gems/coderunner-0.13.32/lib/coderunner.rb:118:in `require': cannot load such file -- trinitycrmod (LoadError)
I don't get this error if I use ruby directly....
ruby `which coderunner` ex ' require "trinitycrmod"'
runs fine. I also don't get this error if I use the system ruby:
rvm use system
coderunner ex ' require "trinitycrmod"'
I also don't get this error if I edit the coderunner bin file and replace ruby_executable_hooks with plain ruby:
sed -i s/ruby_executable_hooks/ruby/ `which coderunner`
This makes me think that it has to be an error with ruby gems and/or rvm and not my mistake, particularly as this code is all at least 6 months old and has worked fine up till now.
PS My gem environment seems to be just fine....

I've installed a number of gems, however when i go to 'require' them i get "no such file to load error":

Checking the gem path for the gem whois and i can see it located there.
Strangely though irb seems to be able to locate the gem:
~/ » irb
irb(main):001:0> require 'whois'

I have been troubleshooting this for about 24 hours now and i feel like i am losing my mind. This issue has only become apparent in the past 24-48 hours. Prior to that the scripts i was playing with were working fine.
Potentially Useful Info
Running OSX Sierra 10.12.4
I am using rbenv and ruby-build
Using Ruby 2.4.1 set globally
PATH = /Users/perfektion/.rbenv/shims:/Users/perfektion/.rbenv/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
Re-installed rbenv, ruby-build, ruby and removed all gems and re-installed.
I feel like it is something stupid, but can anyone see what i am doing wrong here that would be causing ruby to not be able to find these gems?
Thank you!
Update
Not sure why i didn't pick this up earlier, but in the top of my script i have:
#!/usr/bin/ruby
I am not sure why this worked before and it isn't now.
Thanks for the help everyone :)
Whenever you try to run the file it's looking for the gem in the Ruby 2.0 directory. Whenever you do gem env it's showing 2.4.1 as your ruby version.
Keep in mind that with rbenv you can either set a local, global, or shell level version of ruby to run: https://github.com/rbenv/rbenv#rbenv-local
You can also create a .ruby-version file in a directory, and rbenv will look for that and use that version if it exists. Something is off between which version of ruby you are using to install the gem and which one is being used to run your whois script.
when you type ./whois.rb you call the ruby system.
try use ruby ./whois.rb
It will call the RVM/rbenv loaded ruby system
Because ruby is trying to fetch the library from another path that is not the same as the one you installed the wois gem with rbenv. (What could be some conflict with rvm and rbenv, I do not know.)
Try to create a new folder, set ruby 2.4 locally with local rbenv <version> and then try to make require again.
I can finds gems that are installed using gem list, but it doesn't show me where the gems are installed.
How can I find where the gems are, and how can I know before installing a gem where it will be installed?
Use gem environment to find out about your gem environment:

Notice the two sections for:
INSTALLATION DIRECTORY
GEM PATHS
I found it useful to get a location of the library file with:
gem which *gemname*
After installing the gems, if you want to know where a particular gem is. Try typing:
gem list
You will be able to see the list of gems you have installed. Now use bundle show and name the gem you want to know the path for, like this:
bundle show <gemName>
Or (as of younger versions of bundler):
bundle info <gemName>
To complete other answers, the gem-path gem can find the installation path of a particular gem.
Installation:
gem install gem-path
Usage:
gem path rails
=> /home/cbliard/.rvm/gems/ruby-2.1.5/gems/rails-4.0.13
gem path rails '< 4'
=> /home/cbliard/.rvm/gems/ruby-2.1.5/gems/rails-3.2.21
This is really handy as you can use it to grep or edit files:
grep -R 'Internal server error' "$(gem path thin)"
subl "$(gem path thin)"
You can check it from your command prompt by running gem help commands and then selecting the proper command:
kirti#kirti-Aspire-5733Z:~$ gem help commands
GEM commands are:
build Build a gem from a gemspec
cert Manage RubyGems certificates and signing settings
check Check a gem repository for added or missing files
cleanup Clean up old versions of installed gems in the local
repository
contents Display the contents of the installed gems
dependency Show the dependencies of an installed gem
environment Display information about the RubyGems environment
fetch Download a gem and place it in the current directory
generate_index Generates the index files for a gem server directory
help Provide help on the 'gem' command
install Install a gem into the local repository
list Display gems whose name starts with STRING
lock Generate a lockdown list of gems
mirror Mirror all gem files (requires rubygems-mirror)
outdated Display all gems that need updates
owner Manage gem owners on RubyGems.org.
pristine Restores installed gems to pristine condition from
files located in the gem cache
push Push a gem up to RubyGems.org
query Query gem information in local or remote repositories
rdoc Generates RDoc for pre-installed gems
regenerate_binstubs Re run generation of executable wrappers for gems.
search Display all gems whose name contains STRING
server Documentation and gem repository HTTP server
sources Manage the sources and cache file RubyGems uses to
search for gems
specification Display gem specification (in yaml)
stale List gems along with access times
uninstall Uninstall gems from the local repository
unpack Unpack an installed gem to the current directory
update Update installed gems to the latest version
which Find the location of a library file you can require
yank Remove a specific gem version release from
RubyGems.org
For help on a particular command, use 'gem help COMMAND'.
Commands may be abbreviated, so long as they are unambiguous.
e.g. 'gem i rake' is short for 'gem install rake'.
kirti#kirti-Aspire-5733Z:~$
Now from the above I can see the command environment is helpful. So I would do:
kirti#kirti-Aspire-5733Z:~$ gem help environment
Usage: gem environment [arg] [options]
Common Options:
-h, --help Get help on this command
-V, --[no-]verbose Set the verbose level of output
-q, --quiet Silence commands
--config-file FILE Use this config file instead of default
--backtrace Show stack backtrace on errors
--debug Turn on Ruby debugging
Arguments:
packageversion display the package version
gemdir display the path where gems are installed
gempath display path used to search for gems
version display the gem format version
remotesources display the remote gem servers
platform display the supported gem platforms
<omitted> display everything
Summary:
Display information about the RubyGems environment
Description:
The RubyGems environment can be controlled through command line arguments,
gemrc files, environment variables and built-in defaults.
Command line argument defaults and some RubyGems defaults can be set in a
~/.gemrc file for individual users and a /etc/gemrc for all users. These
files are YAML files with the following YAML keys:
:sources: A YAML array of remote gem repositories to install gems from
:verbose: Verbosity of the gem command. false, true, and :really are the
levels
:update_sources: Enable/disable automatic updating of repository metadata
:backtrace: Print backtrace when RubyGems encounters an error
:gempath: The paths in which to look for gems
:disable_default_gem_server: Force specification of gem server host on
push
<gem_command>: A string containing arguments for the specified gem command
Example:
:verbose: false
install: --no-wrappers
update: --no-wrappers
:disable_default_gem_server: true
RubyGems' default local repository can be overridden with the GEM_PATH and
GEM_HOME environment variables. GEM_HOME sets the default repository to
install into. GEM_PATH allows multiple local repositories to be searched for
gems.
If you are behind a proxy server, RubyGems uses the HTTP_PROXY,
HTTP_PROXY_USER and HTTP_PROXY_PASS environment variables to discover the
proxy server.
If you would like to push gems to a private gem server the RUBYGEMS_HOST
environment variable can be set to the URI for that server.
If you are packaging RubyGems all of RubyGems' defaults are in
lib/rubygems/defaults.rb. You may override these in
lib/rubygems/defaults/operating_system.rb
kirti#kirti-Aspire-5733Z:~$
Finally to show you what you asked, I would do:
kirti#kirti-Aspire-5733Z:~$ gem environment gemdir
/home/kirti/.rvm/gems/ruby-2.0.0-p0
kirti#kirti-Aspire-5733Z:~$ gem environment gempath
/home/kirti/.rvm/gems/ruby-2.0.0-p0:/home/kirti/.rvm/gems/ruby-2.0.0-p0#global
kirti#kirti-Aspire-5733Z:~$
You can trick gem open into displaying the gem path:
VISUAL=echo gem open gem-name
Example:
VISUAL=echo gem open rails
=> /usr/local/opt/asdf/installs/ruby/2.4.3/lib/ruby/gems/2.4.0/gems/rails-5.1.4
It just works, and no third party gem is necessary.
gem env works just like gem environment. Saves some typing.

I've decided to move away from rvm to rbenv on my personal machine. Followed the rvm removal instructions, installed rbenv and everything looks peachy. After restarting my shell session:
$ rbenv global
1.9.3-p0
$ ls .rvm
ls: cannot access .rvm: No such file or directory
$ rbenv exec gem list
*** LOCAL GEMS ***
A completely fresh install in a fresh shell--RVM's long gone. Now, when I install bundler
$ rbenv exec gem install bundler
Fetching: bundler-1.0.22.gem (100%)
Successfully installed bundler-1.0.22
1 gem installed
$ rbenv rehash
$ echo $?
0
$ rbenv which bundle
rbenv: bundle: command not found
What? Indeed, look at this nonsense:
$ ls .rvm/gems/ruby-1.9.3-p0/gems/bundler-1.0.22/
bin bundler.gemspec CHANGELOG.md ISSUES.md lib LICENSE man Rakefile README.md spec UPGRADING.md
Somehow, someway, RVM still has its hooks into me. My ~/.bash* files are clean and
$ cat ~/.gemrc
gem: --no-ri --no-rdoc
I have no system ruby, no globally installed RVM (nothing in /etc/profile/, no /etc/profile.d/rvm.sh and nothing in /etc/bash.bashrc) and I'm at a complete loss.

Where else can I look to figure out why gem's configured to install to ~/.rvm?
Something's clearly rotten on my system; no grepping has turned it up, but tacking
unset GEM_HOME
unset GEM_PATH
to the end of my ~/.bashrc made things sane. Horrible hack, though.
Have you ever installed rvm in a system location? Maybe those env vars got into a system-wide shell config.
Try running:
bash -l -x -c 'echo'
This will print bash debugging output so you can see what files are being loaded. It may not show commands inside sourced scripts, depending on your version of bash.
This probably doesn't apply to you, but if it exists, what are the contents of ~/.gemrc ?
I'm running Snow Leopard, and installed a custom built Ruby according to the guide here: http://hivelogic.com/articles/compiling-ruby-rubygems-and-rails-on-snow-leopard . My ruby binary lives in usr/local/bin/ruby and my gems are installed in /usr/local/bin/gem . My gem env looks like so:
RUBY VERSION: 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0]
- INSTALLATION DIRECTORY: /Library/Ruby/Gems/1.8
- RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
- EXECUTABLE DIRECTORY: /usr/bin
I think I may have borked the install since all actions taked on gems give the error:
ERROR: While executing gem ... (Errno::EEXIST)
File exists - /usr/local/bin/ruby
How do you edit the environment variables for the gem environment?
And for those of you on OS X and using ruby AND gems, what did you use to get yourself up and running?
I'm thinking of just nuking everything and starting anew.
It looks like your installation of ruby into /usr/local/bin is not the ruby that you're getting, which probably means /usr/local/bin/ is not in your PATH. If you'd like to run that ruby, try editing your .bash_profile to add /usr/local/bin like this:
export PATH=/usr/local/bin:$PATH
Alternately, you can add the path to a file in /etc/paths.d, which is the preferred method for adding paths globally on an OS X system.
I've tried things about three different ways, each with varying results. I have systems with the default install (/usr/bin), hand-built /usr/local/bin and also Mac Ports in /opt/local/bin.
By far, the simplest is to just use the built-in binary, which on 10.6.2 is ruby 1.8.7. In that scheme, gems are installed in /Library/Ruby/Gems. Second simplest is MacPorts (sudo port install ruby), third is the totally from source method you're describing above. Certainly there are good reasons people install from source, but unless you're trying to run ruby 1.9 or another version, you're best off using the built-in ruby 1.8.7.
Does the command "gem env" not report any gem paths? Mine reports a number of gem paths along with teh version of rubygems etc. that yours does not appear to be doing.

You can edit the environment variables associated with gem by specifying them in your shell startup files, (.bashrc for bash). The relevant variables are all listed in the environment page of the gem web site. You will want to pay particular attention to GEM_HOME and GEM_PATH. You can check the current settings of these by typing echo $GEM_HOME at a shell profile
I would suggest that your best action at this moment in time may be to go back to your default ruby installation as provided with OS/X and then download and install rvm (The Ruby version manager) and then watch Ryan Bates screencast

Im not hot with paths etc but all the gem directories listed above are on the path so how come it cant find the command?
Your $PATH variable needs to include the exact path to your Ruby's bin directory. Adding a directory to the PATH does not include it's subfolders. Try adding the bin directory via:
export PATH=$PATH:/home/adam/.gem/ruby/1.8/bin
or if you installed the gem using sudo:
export PATH=$PATH:/usr/lib/ruby/gems/1.8/bin
You might want to add this to your .bashrc file, so that you don't have to set this manually every time your open up a new bash.
(Just stealing #John Franklin's comment)
$ gem environment
Will tell you the EXECUTABLE DIRECTORY. Then put whatever that value is in your PATH like so (in your .bashrc or other shell config file).
export PATH="$PATH:/path/to/bin"
Reload your shell and you should then be able to use the installed gem.
If you use RVM (most do), then it will take care of this for you. In fact putting it in your path directly may conflict. You have to set a ruby to use though. Run one of these on the command line.
rvm use 1.9.3
or
rvm use --default 1.9.3
