I tried some related solution from stack overflow but none of them is working .
I had this same problem a couple of days ago. What I had to do was delete all versions of RSpec from my machine and then run bundle install. This installed the latest version of RSpec and everything was good afterwards.

I'm new to Jekyll and I'm having a hard time installing the jekyll-polyglot plugin. My latest issues is the following, when trying to run "bundle exec" in the terminal. What is this 'helper x86_64-darwin-19'?
xxxx-xx:sebl xxxxx$ bundle install
Fetching gem metadata from https://rubygems.org/..........
Fetching gem metadata from https://rubygems.org/.
Could not find gem 'helper x86_64-darwin-19' in any of the gem sources listed in your Gemfile.
If I run bundle exec jekyll serve, this is what I currently get:
Alessandros-Air:sebl alessandrolodola$ bundle exec jekyll serve

Dependency Error: Yikes! It looks like you don't have /Users/alessandrolodola/Desktop/SEBL/_plugins/polyglot-master/spec/rspec/helper.rb or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. If you've run Jekyll with `bundle exec`, ensure that you have included the /Users/alessandrolodola/Desktop/SEBL/_plugins/polyglot-master/spec/rspec/helper.rb gem in your Gemfile as well. The full error message from Ruby is: 'cannot load such file -- rspec' If you run into trouble, you can find helpful resources at https://jekyllrb.com/help/!

Attempting to do the Rails tutorial on railstutorial.org. I'm currently at the testing portion of the tutorial and I keep on getting an error when performing the test. The test file I created with 'generate StaticPages controller' command is as is, I have not modified it at all. When I enter in the command 'rails test' I get this error:

If this is formatted and asked imporperly or what not I apologize, any help will be greatly appreciated I absolutely stumped.
Here is the github repo : https://github.com/JDjedi/sample_app
Rails version is 5.0 and ruby version is 2.3.0p0
application_helper.rb_helper.rb - is this how you called your helper? .rb is an extension. Thus could you change the name of the helper file to application_helper.rb and see if that works?
Edit:
Did you look at this question? Rails: AbstractController::Helpers::MissingHelperError - Missing helper file application_helper.rb_helper.rb
Here seems to be a working answer: https://stackoverflow.com/a/28269245/1010826
Simply rename the root folder to the same name. Not sure why that would work, though :)
When reaching step 4 of this guide, which is to create a new rails app:

I thought Database connection not established properly so i tested using the command
rails generate model Test name:string email:string
its working properly, then i gave
rake db:migrate
Now database also migrated successfully, so i think database connection is properly working. The commands mentioned above were run from Engine's Directory. If any information needed comment it out i will provide the details. Thanks

According to http://apidock.com/rails/ActiveModel/MassAssignmentSecurity/ClassMethods/mass_assignment_sanitizer%3D mass_assignment_sanitizer was introduced in rails 3.2, while you are using 3.1.3. Haven't you generated you project with rails 3.2?
