Could not find generator rspec:install (q2)

Question

I'm trying to follow this tutorial here: http://railstutorial.org/chapters/static-pages#top

When I run:

$ rails generate rspec:install

I get:

Could not find generator rspec:install.

What could be the problem?

[Rails 3, 4, 5, 6, 7]

Thanks.

Add to your Gemfile:

group :development, :test do
  gem 'rspec-rails'
end

and run bundle install

make sure that it is in both the :development and :test blocks. If you inadvertently put it only in the :test block, it will give the error above (that's because by default you're running in the development environment and rspec ins't available to that environment).

rails generate rspec:install should then run as expected.

This wasn't working for me until I figured out that I was doing "rails generate rspec::install" (with two colons), instead of "rails generate rspec:install" (with just one like you're supposed to.) If, like me, you're new to ruby and this doesn't work, check your syntax. – Alan W. Smith Dec 16 '11 at 02:25
not sure it installed nokogiri, but installation of 'spec-rails' solves the issue – abhishek thakur Sep 24 '18 at 11:33
Note: version number is optional – gogaz Dec 31 '20 at 11:16
edited answer to clarify this is most commonly because you forget to add it to :development block (only adding it to :test); also removed the previous gem version number as it does not add usefulness to answer -J – Jason FB Nov 23 '21 at 01:12

Make sure you install rspec-rails and not only rspec. Sigh, I lost some time.

I found myself simply not having rspec in gemfile – Anton Semenichenko Jun 22 '20 at 18:58
I had to also `gem uninstall rspec` if it was in my Gem library – Math is Hard Jul 25 '20 at 01:14

If you, like me, created a project, decided you wanted to archive the old directory and start again, but left spring running in the background on accident, spring won't reload from the correct directory and you'll be very confused.

The solution is to stop spring and let it restart on its own.

I had do both gem install rspec and then add to gemfile as Andreas said.

using Rails 3.2.1 and ruby 1.9.3 at windows 7 and worked perfectly.

Remove all rspec versions by running the following commands as suggested by Sydney in another post and then install -V 2.0.1

gem uninstall rspec
gem uninstall rspec-core rspec-expectations rspec-mocks rspec-support
gem install rspec -v 2.0.1

add the following line to the gem file

gem 'rspec-rails', '~> 2.0.0'

and then run

rails generate rspec:install

it runs without any issues

I got this same error and found that i had forgotten to save the Gemfile changes I made in Sublime prior to running the Bundle install command. I saved and then reran the bundle install and was able to run the rails generate rspec:install command

Worth noting this answer. I did the same mistake. Thank you – Kaz Nov 04 '18 at 12:31

Add gem 'rspec-rails' in Gemfile and save it. Run bundle command in Terminal. And in config/application.rb, add this line of configuration

config.generators do |g|
  g.test_framework   :rspec, :fixture => true, :views => false
  g.integration_tool :rspec, :fixture => true, :views => true
end

Restart spring - sometimes it fails to reload after running bundle.

Try installing it as a gem.

gem install rspec

with rails 3 in your config/environment.rb you maintain gems there with bundle install but in terms of what your doing you can just gem install rspec.

Restart spring - sometimes it fails to reload after running bundle. To stop spring you can use bin/spring stop. It should start automatically when you run rails commands.

I just closed and opened a new terminal (following the addition of the gem and running `bundle`) and then the rspec generators were available. I guess spring not reloading was the issue. – aalaap Apr 17 '23 at 05:54

I realized that I had not saved after I updated my Gemfile. I simply saved, ran bundle install on the command line, and finally ran $ rails generate rspec:install

By default I had only 'rspec-rails' in my gemfile, and so bundler installed rspec-rails 1.x (some prehistoric version) for some reason. After I modified my gemfile to have gem 'rspec-rails', '~>3.0' and ran bundle update it ran fine.
