I've recently updated a rails 2.3.10 application to rails 3.0.5. I followed the rails-upgrade gem instructions. Running bundle install works fine. I've update the boot.rb application.rb and environment.rb.
$ bundle install
Using rake (0.8.7)
...
Using railties (3.0.5)
Using rails (3.0.5)
...
However, when I call 'rails server' I still get usage instructions:
$ rails server
Usage:
rails new APP_PATH [options]
Anyone have any ideas why this is happening? I suspect an error is getting swallowed somewhere from the upgrade procedure, but I'm not sure where to look.
I just figured out a way to fix this, so I thought I'd add the step for everyone else to follow.
After doing the rails-upgrade steps:
rake rails:upgrade:check
rake rails:upgrade:backup
build a new rails app over the existing one, by doing the following WITHIN the app's directory.
rails_2_app $ rails new .
And then continue the upgrade as normal.
You need to delete all the existing files under script folder and to create a file called rails under the same folder. The rails file should contain the following:
APP_PATH = File.expand_path('../../config/application', __FILE__)
require File.expand_path('../../config/boot', __FILE__)
require 'rails/commands'
that's all you are good to do. You will have all the commands.

Only i want to create a simple proyect with ruby and rails, but i think its harder than it looked.
I have a version of ruby 2.6.8, i created a new project with this command rails new blog, after that cd to blog
i applied this command: bin/rails server
i am facing this error: bin/rails:4:in require_relative': cannot load such file -- .../rb/blog/config/boot (LoadError) from bin/rails:4:in '
check with command:
ruby -v
that you ruby version same as in gemfile file, also as mention before don't forget run "bundle" after creating new project or add new gem to gemfile.
If this didn't help and you rails version is 6 you can manually fix problem - create boilerplate config/boot.rb:
ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../Gemfile', __dir__)
require 'bundler/setup' # Set up gems listed in the Gemfile.
require 'bootsnap/setup' # Speed up boot time by caching expensive operations.
i am only start learning rails but i think if you only beginner then try fix problem in another way such reinstall rails, ruby etc. bc in future it can cause problem, its not normal when you just create new project and it already dont work, something wrong.
Any rails command doesn't work for me. I have several versions of ruby installed through rvm. I tried installing rails with all the versions, they do install successfully but with all of them I face the following error whenever I run any rails command in my project directory:
~ rails new blog
Traceback (most recent call last):
1: from bin/rails:3:in `<main>'
bin/rails:3:in `require_relative': cannot load such file -- /Users/Am33d/Documents/config/boot (LoadError)
I tried looking up for the error but didn't find any solutions.
What can be done to fix this? I am using macOS Mojave (10.14.6)
This error would indicate that you do not have a boot.rb file in your config directory for some reason. When running rails commands -- regardless of if you run them as bin/rails [command] or bundle exec rails [command], runs the bin/rails file. This file typically has a line require_relative '../config/boot. The boilerplate bin/rails file in a new Rails 6 app is:
#!/usr/bin/env ruby
begin
load File.expand_path('../spring', __FILE__)
rescue LoadError => e
raise unless e.message.include?('spring')
end
APP_PATH = File.expand_path('../config/application', __dir__)
require_relative '../config/boot'
require 'rails/commands'
To simply fix this you can create a blank file by running touch config/boot.rb from the root directory of your application and that would itself suppress the error. Having said that, you'd be better off creating a config/boot.rb file that contains useful information. The boilerplate config/boot.rb file is this
ENV['BUNDLE_GEMFILE'] ||= File.expand_path('../Gemfile', __dir__)
require 'bundler/setup' # Set up gems listed in the Gemfile.
require 'bootsnap/setup' # Speed up boot time by caching expensive operations.
Without this file you are not necessarily appropriately loading the gems from your gemfile or caching operations with bootsnap.
When I ran into this problem, I also received the same error when trying to use rails -s.
If the same is happening for you, its because your version of ruby isn't compatible with your rails version.
After upgrading to the latest rails version the error stopped and everything worked well.
A little bit weird.
rails new blog should not need to find boot file, neither need bundler. Actually, you are trying to create a new project, so it is expected there is not Gemfile, boot, or bundler created for your project.
So I would advise you to find what rails command is being executed. Sometimes one rails executable created by bundler is taking precedence in the $PATH environment variable.
Ex: some incorrect bin/rails executable is on your $HOME directory.
i was trying to build an app using 'rails server' and this error was showing. You have to make sure that the rails version matches the ruby version and even if you do what an answer above said (create the config/boot.rb paste) doesnt work, than you have to change the version of rails to the stable. I'll let the link of this problem here, there's an issue closed in github for this problem https://github.com/rails/rails/pull/43951
to solve the problem you have to replace the gem rails line on the gemfile to this:
gem "rails", github: "rails/rails", branch: "7-0-stable"
Sorry about my english.
I have a ruby on rails api_app and and a test_app that exercises the api_app. While development mode I want to run, from the api_app, a rake task called match:reset that is in the test_app. I am trying to do this with a ruby file that is in the api_app
#!/usr/bin/env ruby
require 'tty-command'
cmd = TTY::Command.new
Dir.chdir('../test_app') do
cmd.run 'run rake match:reset'
end
When I do this I get the following error
Your Ruby version is 2.4.4, but your Gemfile specified 2.4.1 (Bundler::RubyVersionMismatch)
I have tried adding cmd.run 'rvm use 2.4.1' but this does not work. How do set the correct environment so this does work?
I could not get this working with a ruby command file. I think the reason for this is that the file is run with ruby from the api_ppp directory so you cannot change to another ruby. What I ended up doing is using a bash file:
#!/bin/bash
cd ../test_app
source $HOME/.rvm/scripts/rvm
rvm use 2.4.4#test_app_2.4.4
BUNDLE_GEMFILE=../test_lab/Gemfile bundle exec rake -f ../test_app/Rakefile match:reset
I am happy to consider an answer that uses a ruby command file, as long as the answer has been tested.
This solution is not tested, based on the documentation I have made changes to the script.
require 'tty-command'
require 'rake'
cmd = TTY::Command.new
cmd.run("rvm use 2.4.1")
Dir.chdir("../test_app") do
cmd.run(:rake, 'match:reset', env: {rails_env: :development})
end
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
Rails's script/server is just a few lines:
#!/usr/bin/env ruby
require File.expand_path('../../config/boot', __FILE__)
require 'commands/server'
I wonder where the server file is? I tried a
find . -name 'server.*'
find . -name 'server'
but can't find it
You have to look for the files in your related gem repo. Your Ruby is located at
which ruby
Your Rails gem is
bundle show rails
You can go to the dir with
cd `bundle show rails`/lib/commands
Then, open server.rb
thanks. in the case of a Mac, I found that they are on
/Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/commands/server.rb
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/commands/server.rb
/Users/peter/.gem/ruby/1.8/gems/rails-2.3.5/lib/commands/server.rb
the following are there but doesn't have my Rails 2.3.5 version:
/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-1.2.6/lib/commands/server.rb
/Developer/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/gems/rails-2.2.2/lib/commands/server.rb
Update: Now the question is: which of the above 3 is the one? How can you tell easily?
In linux they are more likely to be under
/usr/lib/ruby/gems/ruby_version/gems/rails_version/lib/commands
ruby_version and rails_version depends on which versions you are using. The directory structure will also depend on whether or not you are using rvm, but hopefully you can find your way once you get to the /usr/lib/ruby/ directory
