I'm trying to use spring with rspec and guard on a Rails 3.2.16 project.
After installing spring and spring-commands-rspec, I created the binstubs with :
> bundle exec spring binstub --all
* bin/rake: spring inserted
* bin/rspec: spring inserted
* bin/rails: spring inserted
Now trying to run spec with spring fails (gems paths and project path subtituted for legibility) :
> bin/rspec spec/

Same goes for

Here is the rspec binstub (bin/rspec) :
#!/usr/bin/env ruby
begin
load File.expand_path("../spring", __FILE__)
rescue LoadError
end
require 'bundler/setup'
load Gem.bin_path('rspec', 'rspec')
Any idea ?
I had the same problem. I've solved it by stopping spring and adding to my Gemfile:
gem 'spring-commands-rspec', group: :development, require: false
Spring needs to be restarted in order to use the newly added command.
bin/spring stop
bin/rspec path/to/file.rb
ANSWER OUTDATED! Was fixed. See #pfleidi's answer below.
I've solved the problem, even if i dont know why it has solved the problem.
Just remove gem 'spring', group: :development from the Gemfile so that you only have gem 'spring-commands-rspec' left.
Run bundle install and then spring rpsec spec will work! Its sooo fast :)
You have to restart the spring. So stop it and then re-run it
spring stop
spring rspec
Then it should works as expected.

(See full trace by running task with --trace)
I don't know what causing this issue and can't see a solution for it after hour of searching.
Well this what worked for me
bundle install --binstubs
after it, rails worked without a problem
This is what help give us. I just run this 3 commands and it's work.
Looks like your app's ./bin/rails is a stub that was generated by
Bundler.
In Rails 5, your app's bin/ directory contains executables that are
versioned like any other source code, rather than stubs that are
generated on demand.
Here's how to upgrade:
bundle config --delete bin # Turn off Bundler's stub generator
rails app:update:bin # Use the new Rails 5 executables
git add bin # Add bin/ to source control
You may need to remove bin/ from your .gitignore as well.
I am not sure but maybe it can help
$ spring stop
$ rails generate scaffold User name:string email:string
Can you check if rails s is working.Also try
bin/rails generate scaffold User name:string email:string
If I use spring rake, it runs my project specs to matter what rake task is specified. It just completely ignores whatever is specified at the command line and runs the specs. Here's an example:
$ spring rake routes
/Users/rsilva/.rbenv/versions/2.0.0-p353/bin/ruby -I/Users/rsilva/.rbenv/versions/2.0.0- p353/lib/ruby/gems/2.0.0/gems/rspec-core-3.1.2/lib:/Users/rsilva/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/rspec-support-3.1.0/lib /Users/rsilva/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/rspec-core-3.1.2/exe/rspec --pattern spec/\*\*\{,/\*/\*\*\}/\*_spec.rb
Run options: exclude {:expensive=>true, :migration=>true}
# then runs all the project specs
If I don't use spring, it works fine:
$ bundle exec rake routes
Prefix Verb URI Pattern Controller#Action
# then prints out all the routes
I'm using Spring outside of my Gemfile (I did gem install spring).
Here's the versions of spring and spring-commands-rspec I'm using:
$ gem list --local | grep -P 'spring'
spring (1.1.3)
spring-commands-rspec (1.0.2)
Here's my ~/.spring.rb:
$ cat ~/.spring.rb
require 'spring-commands-rspec'
How do I get spring rake to execute the task specified?
Looks like rake is just executing the default task regardless of arguments passed. This seems to be an issue with rake 10.4.0 and spring. Try upgrading rake to 10.4.1.
https://github.com/rails/spring/issues/366
Guard-RSpec mentions in the README that one could run specs using spring by specifying a cusom cmd:
guard :rspec, cmd: 'spring rspec' do
# ...
end
This used to work fine, until I did a spring binstub --all which changed my bin/spring from...
#!/usr/bin/env ruby
#
# This file was generated by Bundler.
#
# The application 'spring' is installed as part of a gem, and
# this file is here to facilitate running it.
#
require 'pathname'
ENV['BUNDLE_GEMFILE'] ||= File.expand_path("../../Gemfile",
Pathname.new(__FILE__).realpath)
require 'rubygems'
require 'bundler/setup'
load Gem.bin_path('spring', 'spring')
...to...
#!/usr/bin/env ruby
# This file loads spring without using Bundler, in order to be fast
# It gets overwritten when you run the `spring binstub` command
unless defined?(Spring)
require "rubygems"
require "bundler"
if match = Bundler.default_lockfile.read.match(/^GEM$.*?^ spring \((.*?)\)$.*?^$/m)
ENV["GEM_PATH"] = ([Bundler.bundle_path.to_s] + Gem.path).join(File::PATH_SEPARATOR)
ENV["GEM_HOME"] = ""
Gem.paths = ENV
gem "spring", match[1]
require "spring/binstub"
end
end
Now when running guard and hitting enter, it simply tells me this:
[2] guard(main)> <<<<< pressing enter
14:35:35 - INFO - Run all
14:35:35 - INFO - Running all specs
And a notification like "RSpec results - Failed" appears.
When changing my Guardfile and removing spring from the RSpec's cmd like this...
guard :rspec, cmd: 'rspec' do
...the specs are run again, but apparently not using spring?
I also have to mention that when running spring from the OSX terminal, nothing seems to happen:
$ spring
$
So: how must I configure Guard and RSpec to use Spring?
Update
At the moment, I have reverted my bin/spring executable to the version before "binstubbing" it:
#!/usr/bin/env ruby
#
# This file was generated by Bundler.
#
# The application 'spring' is installed as part of a gem, and
# this file is here to facilitate running it.
#
require 'pathname'
ENV['BUNDLE_GEMFILE'] ||= File.expand_path("../../Gemfile",
Pathname.new(__FILE__).realpath)
require 'rubygems'
require 'bundler/setup'
load Gem.bin_path('spring', 'spring')
And the Guardfile looks like this:
guard :rspec, cmd: 'spring rspec' do ... end
This works, but I don't think it's faster than running bare rspec.
So I'm absolutely unsure now how to correctly run RSpec with Spring - using spring rspec or just rspec?
I was looking into this very issue earlier.
Binstubs are wrapper scripts around executables. In Rails they live
inside bin/. If you run spring binstub --all, your binstubs will be
using Spring.
http://makandracards.com/makandra/26083-3-ways-to-run-spring-the-rails-app-preloader-and-how-to-disable-it
Given this fact, you should be able to do something like this to use Rspec with Spring
guard :rspec, cmd: "bin/rspec" do
A little test to verify. Make sure that you have binstubbed rspec already.
bundle binstubs 'rspec-core'
Verify that Spring hasn't been bootstrapped in bin/rspec. The following block should not appear.
[bin/rspec]
begin
load File.expand_path("../spring", __FILE__)
rescue LoadError
end
Shut down Spring. Run bin/rspec and verify that Spring wasn't triggered.
spring stop
spring status
bin/rspec
spring status
If Spring wasn't triggered, you should see this
Spring is not running.
Now bootstrap your binstubs with Spring. Make sure that you have already bundle installed the necessary gems.
[Gemfile]
group :development, :test do
gem "rspec-rails", "~> 3.0"
gem 'spring-commands-rspec'
...
end
[terminal]
bundle install
Update binstubs to use Spring
spring binstub --all
Verify that Spring has been bootstrapped in bin/rspec. The following block should now appear.
[bin/rspec]
begin
load File.expand_path("../spring", __FILE__)
rescue LoadError
end
Shut down Spring. Run bin/rspec and verify that Spring was triggered.
spring stop
spring status
bin/rspec
spring status
Now check to see if the tests run faster after spring has loaded the environment for the tests.
spring stop
time bin/rspec
[output]
real 0m4.981s
user 0m0.144s
sys 0m0.032s
Spring should be running now. Let's see if it's doing its job.
time bin/rspec
[output]
real 0m0.831s
user 0m0.140s
sys 0m0.034s
Yep.
Bottom line, if your binstubs have been bootstrapped with Spring, calling the binstubs will include Spring. And, of course, only commands that have been registered with Spring can use Spring, which is why spring-commands-rspec was included in the Gemfile earlier to support Rspec.
I'm having a really frustrating issue: Rake is being dumb.
Here's how the problem comes about:
$ rails new test_app
$ rails generate scaffold new_scaffold field1:string field2:text
Both of those work just fine, but then when I do this,
$ rake db:migrate
I get the following error.

I've looked about the Internet for similar/same errors, and people have had them. Just no one ever seems to solve the problem!
How do I fix this problem?
A tweet from DHH earlier. Rake .9.0 breaks Rails and several other things, you need to:
gem "rake", "0.8.7"
in your Gemfile.
I made some research just after my previous answer (sorry, I must do before it).
All problems are solved with Rake gem 0.9.2.. I followed these steps:
I installed gem install rake -v=0.9.2 (I had the 0.9.1 gem)
removed the 0.9.1 with gem uninstall rake -v=0.9.1
updated with bundle update
then the db:migrate showed a warning, WARNING: Global access to Rake DSL methods is deprecated. Please....
It was solved by adding the following to the Rake file.
module ::YourApplicationName
class Application
include Rake::DSL
end
end
I ommited the module ::RakeFileUtils extend Rake::FileUtilsExtend option sugested by #databyte.
It means that the Rake gem 0.9.2 works fine!
Going through Chapter 2 of Railstutorial (demo_app) and ran into this problem. I tried all of the other answers listed here, but couldn't get it to work until I did this:
Put this in your Rakefile above require 'rake':
require 'rake/dsl_definition'
via How to fix the uninitialized constant Rake::DSL problem on Heroku?
I also recommitted and pushed all files to Github and Heroku.
All I needed to do was use:
gem install rake
I had version 0.9.2 already, just needed installing.
Reinstall the rake gem and it should work fine:
gem uninstall rake -v=0.9.2
gem install rake -v=0.9.2
If not, specify version '0.8.7' in your Gemfile.
If not using Bundler:
sudo gem install rake -v 0.8.7
sudo gem uninstall rake
Then choose to uninstall 0.9.0.
If like me you're stuck on rake 0.8.7, and you're using Rails 3.2.x then railties adds a requirement for Rake::DSL
To solve this, to the top of your Rakefile you should add:
module Rake
module DSL
end
end
I solved the same problem with the following steps:
In Gemfile:
gem 'rake', '0.9.2'
Then ran this on the console:
sudo bundle update rake
Then added the following lines to Rakefile:
require 'rake/dsl_definition'
include Rake::DSL
Rails 3.1.rc1 has been updated. For your own Rakefiles, you can add this before the call to load_tasks.
module ::YourApplicationName
class Application
include Rake::DSL
end
end
module ::RakeFileUtils
extend Rake::FileUtilsExt
end
https://gist.github.com/4cd2bbe68f98f2f0249f
UPDATE: Also noticed it's already answered here as well: Undefined method 'task' using Rake 0.9.0
I had the same issue and had to use the rake 0.8.7 gem instead of 0.9.0.
I am a Windows XP user and I had the same problem.
I entered gem "rake", "0.8.7" into the gemfile, and then typed the following from the command window.
bundle update rake
This fixed my problem.
Go to your project path
Type bundle install --path=vendor/bundle
Type bundle exec rake db:migrate
To start server type bundle exec rails s. Use bundle exec and you will be sure that you use right gems (required version) for your project.
Also I would recommend you to add vendor/bundle to .gitignore if you use git and make alias for bundle exec. If you use zsh you can follow this approach
Same as Branstar above - thanks Branstar!
OS: Windows Vista
Level: Completely new to Ruby on Rails
I already had Ruby 1.9.2 installed
I followed the instructions in Running Rails 3 on Windows.
All worked up until the "rake db:migrate" part which gave me the same output as original post.
I ran:
gem install rake
I ran again:
rake db:migrate
Then I was able to start the Ruby on Rails server and had everything in place.
Thanks again Branstar :-)
I feel for you (mikhailvs), it's really frustrating. I have been going crazy for almost one full day. I even uninstalled Ruby and all its dependent files and shutdown my PC, but I still got the same problem.
What I got from the error message is the problem with Rake 0.9.2. It seems like it wasn’t fully installed. So I had to reinstall gem install rake -v=0.9.2
I wasn’t sure if I have rake –v0.9.1 installed. So to make sure I’m safe I tried to remove that old version with gem uninstall rake -v=0.9.1. But is showed me the error message
ERROR: While executing gem ... (Gem::InstallError)
cannot uninstall, check `gem list -d rake`
OK, so I checked all Rake directories on my PC, and found I only had Rake 0.9.2.
Then to check if everything went alright, I migrated with rake db:migrate. And it worked :)
I think I didn’t have Rake 0.9.1 because I clean-installed Ruby (rubyinstaller-1.9.2-p180 - on my Windows 7 system) and all gems as well. In the meantime Rake 0.9.2 wasn’t fully installed.
Uninstalling with "gem uninstall rake" worked for me, I had 2 versions installed, so I jest did a clean reinstall.
"rake db:create", to make sure the database exists
and then "rake db:migrate" to seal the deal.
I had the same issue using Rake 0.9.2.2. I solved this problem by using bundle exec.
For Rails 2.3 editing lib/tasks/rspec.rake like in this commit worked for me:
https://github.com/dchelimsky/rspec-rails/pull/11/files
Install rake 0.8.7 and uninstall 0.9.2.2
$ gem install rake -v 0.8.7
$ gem uninstall rake -v 0.9.2.2
Now use
$ bundle exec rake db:migrate
i think this will help you
;)
Run
bundle exec rake db:migrate
it works for me.

Also I would recommend you to add vendor/bundle to .gitignore if you use git and make alias for bundle exec. If you use zsh you can follow this approach
Same as Branstar above - thanks Branstar!
OS: Windows Vista
Level: Completely new to Ruby on Rails
I already had Ruby 1.9.2 installed
I followed the instructions in Running Rails 3 on Windows.
All worked up until the "rake db:migrate" part which gave me the same output as original post.
I ran:
gem install rake
I ran again:
rake db:migrate
Then I was able to start the Ruby on Rails server and had everything in place.
Thanks again Branstar :-)
I feel for you (mikhailvs), it's really frustrating. I have been going crazy for almost one full day. I even uninstalled Ruby and all its dependent files and shutdown my PC, but I still got the same problem.
What I got from the error message is the problem with Rake 0.9.2. It seems like it wasn’t fully installed. So I had to reinstall gem install rake -v=0.9.2
I wasn’t sure if I have rake –v0.9.1 installed. So to make sure I’m safe I tried to remove that old version with gem uninstall rake -v=0.9.1. But is showed me the error message
ERROR: While executing gem ... (Gem::InstallError)
cannot uninstall, check `gem list -d rake`
OK, so I checked all Rake directories on my PC, and found I only had Rake 0.9.2.
Then to check if everything went alright, I migrated with rake db:migrate. And it worked :)
I think I didn’t have Rake 0.9.1 because I clean-installed Ruby (rubyinstaller-1.9.2-p180 - on my Windows 7 system) and all gems as well. In the meantime Rake 0.9.2 wasn’t fully installed.
Uninstalling with "gem uninstall rake" worked for me, I had 2 versions installed, so I jest did a clean reinstall.
"rake db:create", to make sure the database exists
and then "rake db:migrate" to seal the deal.
I had the same issue using Rake 0.9.2.2. I solved this problem by using bundle exec.
For Rails 2.3 editing lib/tasks/rspec.rake like in this commit worked for me:
https://github.com/dchelimsky/rspec-rails/pull/11/files
Install rake 0.8.7 and uninstall 0.9.2.2
$ gem install rake -v 0.8.7
$ gem uninstall rake -v 0.9.2.2
Now use
$ bundle exec rake db:migrate
i think this will help you
;)
Run
bundle exec rake db:migrate
it works for me.
