cannot load such file -- capybara (LoadError) - ruby

I'm trying to run a ruby file that uses capybara and selenium.
When I run cucumber, I get the error :
cannot load such file -- capybara (LoadError)
I saw in another answer that, in order to solve this problem, I had to install poltergeist, but when I run - gem install poltergeist
, I get the error ERROR: While executing gem ... (ArgumentError)
wrong number of arguments (given 1, expected 0)
Any help will be appreciated


You need to include/install the capybara gem, not poltergeist.


I recommend running cucumber with params -v -b , so that you can see where it's failed with verbose & backtrace log.
cucumber -v -b <your_cucumber_features/tag>
The message
cannot load such file -- capybara (LoadError)
was prompted when you've defined to use capybara in your ruby file but your machine hasn't been installed that gem. So need installing capybara via
gem install capybara
However, gem will be installed to specific RVM, so that if you have any error, then try to see which Ruby version that you install onto your system. I suggest install rbenv so that you can manage it better.

Ruby - Can't require gem properly

I'm trying to require the gem 'cerebrum'. I tried requiring it using the irb, and that worked, and also running the program in JRuby worked too. However, Ruby throws a LoadError.
C:/Ruby23-x64/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- cerebrum (LoadError)
from C:/Ruby23-x64/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require'
What am I doing wrong? Has anyone had that issue too?

You get the load error when gem is not installed. First check if this gem is installed in this ruby version using gem list cerebrum. It may be installed in your jruby that's why it didn't throw error.

Not able to install bundle

I am new to development of Capybara with Rspec using Ruby with selenium. I have installed Caybara and installed RSpec also. But when I am trying to install it is giving an error "Couldn't locate Gemfile". How to rectify the error? How to locate the Gemfile. Is there any Tutorial for Capybara and Rspec to understand better about those?
I am installing those on Windows8.1Pro

Getting an error with Ruby/Selenium

I am trying to use Selenium with Ruby. I am new to Ruby, I set it up using this blog http://testnerdy.blogspot.ca/2009/10/installing-ruby-and-selenium-on-windows.html
and the Ruby script I used is from here - http://testnerdy.blogspot.ca/2009/10/running-selenium-tests-written-in-ruby.html
When I ran the script, I get this error
SeleniumRubyWindowsTest.rb:1:in `require': no such file to load -- selenium/client (LoadError)
from SeleniumRubyWindowsTest.rb:1
Any ideas on what I may be doing wrong?

Have you installed the selenium gem? If so, depending on your version of ruby you may need to do a
require 'rubygems'
as the first line of the script to pull in all the gem dependencies, which selenium could be one.

Including gems in ubuntu 11.04

I've got a problem with running an additional gem under ubuntu 11.04. I installed spiceweasel via gem install - which put it in /var/lib/gems/1.8/gems/spiceweasel. When I try to run it, I get:
`require': no such file to load -- spiceweasel/version (LoadError)
The file is in /var/lib/gems/1.8/gems/spiceweasel-0.7.1/lib/spiceweasel/version.rb but cannot be loaded. This happens both with and without -rubygems.
How do I fix this?

It seems to be the same problem like here: Ruby: require 'irbtools' raises LoadError
The gem author published the gem with wrong permissions. You should contact the gem author.

I see gem in "gem list" but have "no such file to load"

I am on Ubuntu10
sudo apt-get install ruby1.9.1-full
then download sources of rubygem 1.3.7 and install it
sudo ruby setup.rb
then, for example, install sinatra
sudo gem install sinatra
Finally open irb and type
require "rubygems"
require "sinatra"
and get error
LoadError: no such file to load -- sinatra
from (irb):2:in `require'
from (irb):2
from /usr/bin/irb:12:in `<main>'

I had exactly this problem. The problem is that gem and ruby disagree about where the gems live. Compare these:
ruby -e "puts Gem.path"
gem env
gem which sinatra
If you're like my setup, you'll notice that there's an entry in gem env's paths that isn't in Gem.path, and that's exactly where sinatra will claim to be. In my case, I had to add
export GEM_HOME=/usr/lib/ruby/gems/1.9.1
to my .profile. Then everyone was happy.

Execute
sudo gem install sinatra --verbose
and note the path where the gem is getting installed.
Then try this in irb
puts $LOAD_PATH
and make sure that gem is installed in one of the directories in $LOAD_PATH
And ideally just start using http://rvm.beginrescueend.com/

I usually hit this error when I forget:
require 'rubygems'
It'd be helpful if you provided the actual code sample, though, what gem you want to require, and what Ruby version you're using if this doesn't solve the problem.

This was before here on SO quite a few times. Problem is that you probably have two versions of ruby. The one is installing the gem and the other one is trying to use it. Do this in terminal:
$ which -a ruby
Or this:
$ which -a gem
to see if you have more than one version of ruby/gem installed. If so - remove one version (via $ rm or package manager of your system).

I use ruby gems 1.8.7 for a project. I was getting the same error. Use the line require 'rubygems'. It must always be the first require statement, otherwise you can get an error. In my code, I had
require 'watir'
require 'rubygems'
# more code
I got the error - in `require': no such file to load -- watir (LoadError).
When I put rubygems first, the error went away and everything worked. I don't know
why this happens.
Btw, I tried user24359 answer and it did not help me.
C:\code>ruby -e "puts Gem.path"
-e:1: uninitialized constant Gem (NameError)
