I'm a newbie at Ruby on Rails. I'm trying to update the Gem file but it keeps giving me this error.
Your Ruby version is 2.3.3, but your Gemfile specified 2.3.0
The reason I'm trying to update the gem file is because of a security vulnerability .
check your gemfile, there will be
ruby '2.3.0'
you need to change it to
ruby '2.3.3'
more you can read here https://bundler.io/v1.12/gemfile_ruby.html and https://devcenter.heroku.com/articles/ruby-versions
Just change your ruby version at gem file to the version suggested by the error. Let's see if this works

I am working on a project that requires Rails 2.3.3. I have Rails 5.2.2 already installed in my system.
I am asking how to install Rails 2.3.3 and work on that project. Any links would be much appreciated.
You can use rvm for different rails applications.
Try this link https://rvm.io/rvm/install.
After installing rvm. in your gem file you can mention your rails version. it will install automatically.
gem 'rails', '~> 2.3.3'
I am using Ruby 2.4.2. When I run bundle install, it shows the following error:
Your Ruby version is 2.4.1, but your Gemfile specified 2.3.3
It showing this error because in your Gemfile you have specified Ruby version '2.3.3'.
You have two options: one is to remove the Ruby version declaration from your Gemfile, the second to specify the version that is installed on the system in Gemfile.
ruby '2.4.1'
It should be like that in your gemfile.
If you want to use Ruby '2.4.2' then install it in your system and specify the same in Gemfile. You can use RVM or rbenv to manage multiple versions of Ruby.
I have downgraded my ruby-2.2.2 to ruby 1.9.3p551 and rails 4.2.4 to 3.2 version for my project now i am getting the dependency error of gemfile. How can I resolve these errors .? Is it possible to downgrade like this?
You need to change version of your gems, and then invoke
bundle update
You have few options to specify how bundler should resolve dependencies. But when you didn't specify version of gem, then bundler choose latest compliant version.Eg
gem 'sample_gem'
gem 'sample_gem', '1.0.0'
gem 'sample_gem', '>=1.0'
gem 'sample_gem', '~>1.1'
So remove version from gem version you don't care and then let bundler resolve dependencies.
I'm making a project and when I run a generate command I get the following error:

I have to use ruby version 2.3.1 for my project so I have attempted changing my Gemfile version.
my gemfile now contains this:
ruby "~> 2.3"
I have tried all sorts of commands so that the Gemfile recognises that I want to use a different ruby version. I have tried:
bundle update
bundle install
gem bundle install
rbenv rehash
even my Gemfile.lock says it is using 2.3.1:
RUBY VERSION
ruby 2.3.1p112
I have even deleted the project and started again.
Please help
An update: I deleted the project and restarted. here are the exact steps I took from my home directory
ruby -v: #2.3.1
git clone https://github.com/kevinhughes27/shopify-sinatra-app.git
gem install shopify-sinatra-app
shopify-sinatra-app-generator new myshop
and the same error as above appeared:
Your Ruby version is 2.3.1, but your Gemfile specified 2.2.2
My Gemfile looks like this:
source 'https://rubygems.org'
gemspec
it's practically empty... I haven't even specified the ruby version
I then ran
bundle install
bundle update
still the same error appears.
I then specified in my Gemspect the ruby version and it now looks like this:
source 'https://rubygems.org'
ruby "2.3.1"
gemspec
but still the same error appears
I don't think you can use version specifiers like that for the Ruby version. I've never seen any examples with that.
Perhaps try it like this if you want v2.3.1:
ruby "2.3.1"
The attempt you're taking here:
ruby "~> 2.3"
seems like the right approach, but you should use an exact Ruby version:
ruby "2.3.1"
It's worth mentioning that you don't necessarily need to manually specify your ruby version anywhere if you don't want to.
updated answer
i cloned the gem and tried installing it. I got the same error. I figured out where the source of the 2.2.2 dependency is. It's in the gem's source code, which for me is ~/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/shopify-sinatra-app-0.3.0. In examples/Gemfile there is a ruby '2.2.2' line.
I tried removing this line, but there was a different error installing activesupport. I think it's likely that the easiest solution for generating an app with this gem would be to install ruby 2.2.2
I've been away from programming for a few months but I'm back now and surprised to rails already at version 3.2.8. I feel slightly rusty and forgot how to successfully upgrade my ruby on rails version to the latest.
I'm currently using version 3.2.3
Is there a standard way of upgrading? I remember the last time I upgraded I had to modify some lines in the gemfile. A google search didn't help so I would appreciate a solution from my favourite place thanks.
Kind regards
If you just want to install the latest rails gem
gem install rails -v 3.2.8
If it's a rails 3.2.3 app
Edit Gemfile, changing the line gem 'rails', '3.2.3' to gem 'rails', '3.2.8'
Run bundle update rails
(from this so question)
For each app you want to upgrade:
Gemfile
gem 'rails', '3.2.8'
# ...
Then on the command line:
$ bundle update rails
