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 want to change ruby 2.3.5 line in gemfile to ruby 2.4.2
but i did not know how?
inside your working folder there is file .ruby-version, change the content from 2.3.5 to 2.4.2 and then run steps below, if you working with rbenv
gem install bundler
rbenv rehash
ruby -v
# make sure it said 2.4.2
bundle install
Just open your Gemfile in a text editor and change the
ruby '2.3.5'
to
ruby '2.4.2'
You need to open your Gemfile and update ruby version ruby '2.4.2' Then you will need to go to terminal and install that version if not already installed. Use rvm use 2.4.3 (if you are using rvm) command to select 2.4.3 version.
I have a problem when running bundle install in the root of sharetribe rails's project. It shows me this error message:
Your Ruby version is 2.4.0, but your Gemfile specified 2.3.1
I tried installing rvm and installing the 2.3.1 version required to run this project but nothing changes and it still throwing this output.
Have anyone faced this problem before ?
Your Ruby version is 2.4.0, but your Gemfile specified 2.3.1
Steps to resolve this issue
1)rvm install ruby-2.3.1
2)gem install bundler
3)rvm use ruby-2.3.1
4)Bundle install
Your Ruby version is 2.4.0, but your Gemfile specified 2.3.1
If you run command ruby -v you can see that you have installed Ruby 2.4.0, when you look at the first line in your Gemfile specifies that you want to use Ruby 2.3.1.
You can do either install Ruby 2.3.1 or replace the first line in your Gemfile to with Ruby 2.4.0.
What does it say when you run bundle env in the terminal?
Is it the same ruby version?
I tried gem install bundler one time i had the same problem and bundle updated and worked.
You can read more about it here.
Good luck!
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
Is it possible to run a Ruby application that was developed in Ruby 2.1.2 on a machine that has Ruby 2.1.5 installed? I'm new to Ruby and I'm starting to think that's not possible. A newer version of Ruby cannot run an older one? Can someone confirm?
When I type "rails server" I get the error message saying "You ruby version is 2.1.5, but your Gemfile specified 2.1.2 (Bundler::RubyVersionMismatch)". One of the messages it gives me is "ruby-2.1.2 is not installed". And then it says "To install do: rvm install ruby 2-1-2"
I tried commenting out the ruby version in Gemfile and/or changing the version number but I get more error messages now:
Juste remove/comment your version of ruby specified in Gemfile like this
#ruby '2.1.2'
Or install ruby '2.1.2' with RVM (Ruby Version Manager) on your environment:
RVM
In terms of recent history, the biggest shift in the Ruby language was between Ruby 1.8 and Ruby 1.9 where a number of things caused conflict due to changes in syntax and enforcing UTF-8 encoding.
Ruby 2.0 and 2.1 introduce more features but don't really impact backwards compatibility. It's very rare that a shift from 2.1.2 to 2.1.5 would cause problems with one exception:
You will probably need to reinstall all your bundled gems.
Normally this is done with:
bundle install
Note that Bundler itself is a gem, so you may need to install that if the bundle command is not available for that version of Ruby:
gem install bundler
If you're having a conflict due to mismatched Ruby versions in your Gemfile, edit that file to reflect your desired version.
Many multi-version Ruby managers like RVM and RBenv use a .ruby-version file in the main application directory to specify this instead. This is a gentler approach than locking down your Ruby version in the Gemfile itself.
If you need to install a new version of Ruby on your server:
rvm install 2.1.5
rvm --default 2.1.5
rvm use 2.1.5
gem install bundler
bundle install
That should make it available.
I create a gemset with
$ rvm gemset create r3
$ rvm gemset use r3
$ gem install rails -v3.2.13
At this point
$ rails -v
now shows
$ Rails 3.2.13
but every time I do bundle with a project I've forked, I find that
rails -v
shows Rails 4.0.1 - which then gives issue with the project in question when running tests
(4.0.1 conflicts with 3.2.13).
My question is - if my Gemfile only has:
$ cat Gemfile
source 'https://rubygems.org'
gemspec
how is this happening? How can I make my command line ruby version stay at 3.2.13 and not switch to 4.0.1 Once it switches to 4.0.1 I seem to be stuck with that for that gemset and to create a 3.2.13 gemset I have to start over again.
Bundle works by finding the most up-to-date version of the gems that are compatible with the restrictions from the Gemfile. In this case, those restrictions are coming from the gemspec file, which presumably allows versions of Rails greater than 3.2.13. So it's picking the most up-to-date version of Rails allowed - which is 4.0.1. Your RVM configuration is not relevant here.
To lock your particular fork to Rails 3.2.13, just add the following:
gem 'rails', '3.2.13'
to the Gemfile in your fork. This will lock the local version to 3.2.13 when you run bundle.
if you wish to explicitly use different version of rails then the one that would be calculated from Gemfile then you need to use:
NOEXEC_DISABLE=1 rails ...
you can make it permanent for single shell session with:
export NOEXEC_DISABLE=1
rails ...
and to disable loading gems in versions calculated via Gemfile put it in you shell initialization file (like ~/.bash_profile or ~/.zlogin):
export NOEXEC_DISABLE=1
this happens because RVM installs gem rubygems-bundler which automatically analyzes your Gemfile when you run gem binaries and if a version specified via this file is available then it is loaded (even if it is specified only as dependency of your gems).
