I am trying to use Rspec for my test. When I run
$ rspec mytest_spec.rb
I get the following error due to the
/home/bastien/.merbenv/versions/2.2.2/lib/ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- rails_helper (LoadError)
I have tried many things and somehow if I run
rspec spec
or
bundle exec rspec
from the folder where my .rspec file is I do not get any error. I have created an app just to dry test this issue (I created a new rail app, added rspec in my Gemfile, run the bundle install command and the rspec:install command, generated a scaffold and run the tests. Could anyone explain to me why I get this issue and how I can get rid of it? Do I do something wrong when I try to run only one single spec? Thanks.
You are getting that error because you're trying to call your spec like this...
rspec mytest_spec.rb
You need to call it like this from your app's root folder , not inside the spec folder. So first get in the right folder
cd ~/
cd path_to_your_rails_app
Then call your spec
rspec spec/the_rest_of_the_path_to_your_spec/mytest_spec.rb
for instance
rspec spec/models/mytest_spec.rb
For others who find this:
I got this error, 'require': cannot load such file -- rails_helper (LoadError), when I had included the rspec-rails gem but hadn't run rails generate rspec:install which generates the spec/rails_helper.rb file. So if the other solution doesn't help you, make sure you've done that.
For those that the answers above didn't help:
You just need to add gem 'rexml' to your Gemfile.rb, run bundle install and try again.

I am trying to run rspec for Ruby on Rails. I am running Rails 4.1.1. I have installed the gem, have established a spec folder with some tests. I have created a directory through $ rails g rspec:install
I tried to create a testing database through $ rake db:test:prepare but it throws this error message:
WARNING: db:test:prepare is deprecated. The Rails test helper now maintains your test
schema automatically, see the release notes for details.
So I ended up looking at this stack overflow post, and of the two options, the one that worked was:
rake db:schema:load RAILS_ENV=test
So, now I need to run rspec.
When I run $ rspec spec from the command line I get this error:
/Users/myname/.rbenv/versions/2.1.1/lib/ruby/2.1.0/rubygems/core_ext/
kernel_require.rb:55:in `require': cannot load such file -- rails_helper (LoadError)
How do I resolve this so that I can start running tests?
There is some problem with rspec V3. But in your case you are using V2.
change
require 'rails_helper'
to
require 'spec_helper'
Other description find here https://teamtreehouse.com/forum/problem-with-rspec
For V3 :
If someone using rspec V3 then similar error occurs when generator not run. So before trying anything run generator.
rails generate rspec:install
If you are getting a huge list of warning on your console. Then you need to remove --warnings from .rspec file.
I actually just had this error on rails 4 with rspec 3, but in my case I forgot to run the generator:
rails generate rspec:install
Also I had to remove warnings from .rspec, as stated by one of rpsec developers
For me, the problem was due to a different "rspec-support" version loaded and activated. I solved by prepending a "bundle exec":
bundle exec rspec
Always remember to run the
rspec or the bundle exec rspec from the root of your project.
Something like:
bundle exec rspec spec/features/file_test_spec.rb
For newer versions (3.5), if you need to run the generator, rails generate rspec:install doesn't work for me. I used:
rspec --init
Creates .rspec and spec/spec_helper.rb.
EDIT:
Just in case, I found out that I installed rspec gem for ruby, not the one for Rails, so rspec:install wasn't available. Should use https://github.com/rspec/rspec-rails.
Sometimes you need to run rspec command from Project's parent directory
Please install the following gem:
gem install 'rspec-rails'
And then run:
rails generate rspec:install
This will generate the spec folder and rails_helper.rb and spec_helper.rb. Your error should be taken care once this is done.
None of these suggestions worked for me on Rails 4.2.0 with rspec-rails 3.2.3.
Instead, I placed the following two lines at the top of my spec file:
require 'rails_helper'
require 'spec_helper'
Now I can execute rspec spec/features/my_spec.rb.
I had the same error but there was no reference to rails_helper anywhere and we weren't even using rails.
However, I eventually found that my ~/.rspec was requiring rails_helper (presumably from creating rails app in the past) which was causing the issue ...
$ cat ~/.rspec
--color
--format documentation
--require spec_helper
--require rails_helper
The fix is as simple as removing that line. Hope this helps someone else grappling with the same issue!
One possibility that worked for me is to make sure you're requiring spec_helper. RubyMine can default require rspec and this can sometimes lead to this error.
You may also have your file named incorrectly. Make sure it ends in _spec.rb. I had misspelled my file to end in _soec.rb and was scratching my head for a while...
I got the error you described when running a controller test. However, when I ran a model test, I got the true error. it ended up saying that the error was occuring because my database wasn't migrated. I fixed the error by running this command...
rake db:test:prepare
For someone. If you got that error when you trynna test a specific file. you might can like this
$ bundle exec rspec ./spec/features/user_login_spec.rb
$ bundle exec rspec ./spec/models/user_login_spec.rb
I have a ruby script I wrote which generates data and loads it to MongoDB. I am now trying to call this load script from seed.rb of my Rails app (so I can run via rake db:seed)
I attempted to call it from rails using this code:
system( "ruby data_load/db_load.rb -a data_load/doc1.json" )
When that code executes, I get the following error. (Note it runs fine from the command line):
data_load/db_load.rb:15:in `require': cannot load such file -- mongo (LoadError)
from data_load/db_load.rb:15:in `<main>'
The top of db_load.rb looks like this:
# includes gems from gemfile
require 'rubygems'
require 'bundler/setup'
Bundler.setup
require 'mongo'
require_relative 'load_scripts/cmd_options'
require_relative 'load_scripts/build_index'
....
include Mongo
The script has it's own gemfile in the data_load directory.
My guess is ruby is running the script using the bundle for the rails application instead of the shell script.
Any suggestions on how I can execute this script?
I believe the problem is where Bundler is looking for the Gemfile. Since your script is being run in the parent directly it is finding the Gemfile for the main app.
Set the BUNDLE_GEMFILE before calling your script:
system "BUNDLE_GEMFILE=data_load/Gemfile ruby data_load/db_load.rb -a data_load/doc1.json"
I'm sorry but I think you can't do it, unless you run the script as a different process (like a shell command), doing it is easy:
`shell_command params`
Just use the correct path and params.
Otherwise, consider that a gemfile is "more or less" at its basic level, a bunch of require (or load) statements, so loading a different gemfile would overwrite the original one, creating a lot of issue with rails after that.
The subprocess command is a good idea, however you can only pass string as params, not in-memory objects.
I'm getting a very strange error from rspec:
$ rspec spec
invalid option: --default_path=spec
I'm in a rails 4, ruby 2 app and I've updated everything to rspec-rails 3.0.0.beta. I've dumped and re installed rspec, .rspec, and spec_helper.rb.
You're probably using a different version of RSpec. The tests run fine from the balanced-ruby project. Make sure you have this line in the Gemfile:
gem "rspec", '~> 2.10'
Then run bundle install and finally try again with bundle exec rspec spec.
This is old but for whomever Googles this: in addition to checking your Gemfile, take a look at your repo's .rspec config file to see if there is an issue. If that doesn't fix it, check your environment to see if you have a global .rspec config file. Try cat ~/.rspec to see if you have one and if there are any issues with it. The global config caused issues for me.
I installed the autotest gem and intend to use it with rspec. The problem is, when I run autotest under my rails app, all I see is :
railsapp$ autospec
loading autotest/rails_rspec
And its stuck there until I Ctrl-C out of it. Nothing changes even if I change a rspec test or code.
Here's my ~/.autotest
require "autotest/restart"
require 'redgreen/autotest'
require 'autotest/fsevent'
require "autotest/growl"
I had the same problem. I was eventually able to get everything working by making sure I was on the latest (beta, if necessary) versions of rspec, rspec-rails, autotest, and autotest-rails, and putting the following in autotest/discovery.rb:
Autotest.add_discovery { "rails" }
Autotest.add_discovery { "rspec2" }
Here's the blog post that got me started in the right direction.
I had the same problem, and this fixed it:
"Make sure you have a .rspec file in the project root. That tells RSpec to tell Autotest to load RSpec’s autotest extension."
ref: https://github.com/rspec/rspec/wiki/autotest
It seems as if my .rspec file had gotten deleted when messing around with git.
Cd into app directory and run the command: AUTOFEATURE=true autospec
To stop this process ^C twice
I had the same problem with Rails 2.3.2 except that I'm not using RSpec. In my case, installing the autotest-rails-pure gem got it working for me. Maybe autotest requires the correct plugin in order to detect a test within a file.
I'm trying to use collectiveidea's delayed_job gem
The installation instructions include
Rake tasks are not automatically loaded from gems, so you’ll need to add
the following to your Rakefile:
begin
require 'delayed/tasks'
rescue LoadError
STDERR.puts "Run `rake gems:install` to install delayed_job"
end
Where is my Rakefile? And what is a Rakefile?
I had the same problem with rails 3.1 and collectiveidea-delayed_job.
Once I added Delayed::Worker.backend = :active_record in the initializer I got the error
no such file to load -- delayed/backend/active_record (LoadError)
The solution for me was to add gem 'delayed_job_active_record' in the gemfile, as suggested here
I have the same problem and put that code in delayed_job.rake in the lib/tasks directory. It works, but now It say's:
*** Starting job worker localhost pid:79949
rake aborted!
uninitialized constant Delayed::Job
What is wrong now?
UPDATE: I just got a mail answer from Brandon:
Theres a bug in the latest version where it doesn't get properly initialized when using the rake task. If you create a file in config/initializers and put the follow in it, the error should go away:
Delayed::Worker.backend = :active_record
The Rakefile is a file that is used to configure rake, a Ruby build tool (sort of like make, but all in Ruby). In a Rails project, there is a file in the top project directory named Rakefile where you can insert this code.
Alternatively, you can add a file into the lib/tasks directory (for example named delayed_job.rake) and put the code into there. The name of the file is not important as long as
It is in the lib/tasks directory
It has the extension .rake
