If you run <code>ruby -v</code> you're going to see that you've installed Ruby 1.9.3, but the first line in your Gemfile specifies that you want to use Ruby 2.0.0.

You should either install Ruby 2.0.0 or change the first line in your Gemfile to specify Ruby 1.9.3.

sample of Gemfile:

<pre><code>source 'https://rubygems.org'
ruby "1.9.3"

I had this exact issue - just a few seconds after watching Mac OSX Terminal confirm that Ruby 2.0.0 was successfully installed. 

Mac OSX ships with an out-of-date version of Ruby already installed and set as the default Ruby. In order to correct the issue, you can install "JewelryBox", a charming and lovely app that gives you a GUI to view and manage multiple rubies (helpful if you have multiple dev environments on one Mac). You can use it to deselect Mac OSX's default Ruby and select your newly installed Ruby.

If you are using a Ruby version manager like RVM or rbenv, then create, in the top-level directory of your project, a file named <code>.ruby-version</code> containing the version spec'd in your Gemfile, e.g.:

<pre><code>2.0.0

That apparently is the cross-<code>{rbenv,rvm}</code> way of spec'ing the version now.

None of these worked for me, but I finally figured it out:

<pre><code>spring stop

I had a Rails 4 project that uses something called Spring to keep a Rails environment running in the background, for speed.

I had started Spring with Ruby 2.1.1 but then I upgraded to 2.1.2 (in Gemfile and .ruby-version). My theory is that Spring kept on running on 2.1.1 and so caused this error.

In response to this post, you have to make sure you run <code>rbenv rehash</code> after you install a ruby version. That seemed to work for me when I ran into the same problem.

I tried literally every solution to this problem that I could find on the web and at the end of the day it turns out my problem was caused because I had accidentally installed a Rails app in Users/MyName, and it was reading that Gemfile.

Came across this error while using the passenger gem. Since I installed this gem with sudo access, it took a default version of ruby on its own. I believe the reason could be that ruby was installed without sudo access on my system and passenger didn't know the actual version of ruby to be used.

However, installing the gem and its apache module without sudo access fixed the problem.

Suggestion for anybody finding this issue and none of the typical solutions resolve this issue for you, check to see if you have more than one ruby version manager. There are multiple version managers, and some software or install scripts will use different ones. I know of <code>rbenv</code>, <code>rvm</code>, <code>asdf</code>, and at least one other that I don't recall the name of. I had <code>asdf</code> installed by a different tool without realizing it happened and it caused the specified version mismatch.

To check for this execute <code>which ruby</code> and look carefully at the path. If it's not the actual version manager you are expecting, you are suffering from this issue. Simplest fix is to use the one you want, and get rid of the other one. If for some reason you need to keep both, you will probably need to change the order of paths in your shell's .rc file.

the main reason for this problem is your machine and gemfile using a different ruby version 

so there is multiple problems and solutions for this issue you can try the below solutions one by one 

1- make sure your machine install and use the same version of your gemfile if your machine not using the same one try to install this version using rvm 

<pre><code>$ rvm install ruby_version_you_want
</code></pre>

make sure the version installed success by using this command 

<pre><code>$ rvm list
</code></pre>

and if the new version doesn't set as a default you can set it using this command 

<pre><code>$ rvm --default use ruby_version_you_want 
</code></pre>

you can check the current ruby version 

<pre><code> $ rvm current 
 $ ruby -v 
</code></pre>

2- if you have the same issue check your bundler 

<pre><code> $ gem install bundler
 or
 $ gem update bundler 
</code></pre>

3- in some cases spring still using the old version so you need to stop it 

<pre><code>$ ./bin/spring stop
</code></pre>

4- another case you can type 

<pre><code>$ gem pristine --all 
</code></pre>

and try to install bundle again 

5- also in some cases after install the updated ruby version you just need to restart your terminal.

6- another solution but I didn't recommend it the top-level directory of your project, create a file named .ruby-version containing your active running ruby version 

7- if you still have this problem try to remove ruby and install the updated version only 

<pre><code> $ aptitude purge ruby 
</code></pre>
