Your Ruby version is 2.0.0, but your Gemfile specified 2.1.0
RubyGemfileRuby Problem Overview
When I try to bundle install I get the following message:
Your Ruby version is 2.0.0, but your Gemfile specified 2.1.0
In my Gemfile I have the following:
ruby '2.1.0'
And when I run ruby -v
in the console I get:
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin12.0]
What does Ruby 2.1.0p0 mean? What version should I have in my Gemfile and why does the error tell me I have Ruby version 2.0.0?
Ruby Solutions
Solution 1 - Ruby
Run
gem install bundler
or
gem update bundler
which may fix your problem.
For all new installed versions of Ruby you should update or install a new bundler.
Solution 2 - Ruby
In the top-level directory of your project, create a file named .ruby-version
containing (wait for it...)
2.1.0
That apparently is the cross-{rbenv,rvm}
way of spec'ing the version now.
Solution 3 - Ruby
If you get this in a Rails project, and you recently upgraded your Ruby version you might have spring still running with the old version of Ruby.
./bin/spring stop
will fix this.
Solution 4 - Ruby
For me, none of the answers helped. I fixed it closing and opening again the terminal.
Solution 5 - Ruby
None of the other suggestions was working for me. On the server, I had to do:
rvm --default use [correct version number]
Solution 6 - Ruby
brew cleanup ruby
worked for me as I use HomeBrew to install Ruby.
I recently updated Ruby through HomeBrew but HomeBrew did not remove the older version. brew cleanup ruby
will delete the older version of Ruby.
Solution 7 - Ruby
If you are using Capistrano you should also check your deploy.rb
file for the set :rbenv_ruby
configuration.
Solution 8 - Ruby
I got this after upgrading with ruby-install. Fixed this with:
gem install bundler
followed by:
$HOME/.rubies/ruby-2.4.1/bin/bundle
It shouldn't be necessary to specify the path as which bundle
indicates it's already using this path. But it gives the version error if running bundle
without the path. I don't know why?
Solution 9 - Ruby
Thanks for the info about installing / updating bundler but it didn't work for me.
I had to do rbenv rehash
Solution 10 - Ruby
If you are using rbenv to manage your ruby environments you can run rbenv local 2.1.0
within your project directory to set the version of ruby your gemfile asks for.
Solution 11 - Ruby
NONE of the above answers worked for me, but
$ gem pristine --all
did the trick for me
buona fortuna
Solution 12 - Ruby
I struggled with something very similar, just different versions. I finally fixed it by going to RubyGems and placing the latest version of bundler in my gemfile, which currently is:
gem 'bundler', '~> 2.1', '>= 2.1.4'
There was still an issue, but after that, I ran:
gem update --system
And it resolved the mixed-up versions of Ruby in the rails project folder. You may have to restart the terminal before you do this. Also, I commented out the bundler gem file, it appears the gem update --system command is what really resolved it.
I got it from here:
Solution 13 - Ruby
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
$ rvm install ruby_version_you_want
make sure the version installed success by using this command
$ rvm list
and if the new version doesn't set as a default you can set it using this command
$ rvm --default use ruby_version_you_want
you can check the current ruby version
$ rvm current
$ ruby -v
2- if you have the same issue check your bundler
$ gem install bundler
or
$ gem update bundler
3- in some cases spring still using the old version so you need to stop it
$ ./bin/spring stop
4- another case you can type
$ gem pristine --all
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
$ aptitude purge ruby
Solution 14 - Ruby
For more advanced projects .versions.conf is supported, where more than the Ruby version can be specified.
Generating .versions.conf:
rvm --create --versions-conf use 1.9.3@my_app
Example .versions.conf:
ruby=jruby-1.6.8
ruby-gemset=my_app
env-JRUBY_OPTS=--1.9
Solution 15 - Ruby
Make sure your server configuration points to the correct ruby installation.
I had already updated my Ruby version in the .ruby-version
file and that didn't fix it. ruby -v
also showed the correct version, but I had forgotten to update my server config.
For example, with rbenv, NGINX, and Pushion Passenger I had in my NGINX server block:
passenger_ruby /Users/myusername/.rbenv/versions/2.3.1/bin/ruby;
And I needed to change to...
passenger_ruby /Users/myusername/.rbenv/versions/2.3.3/bin/ruby;
Then restarted NGINX and it worked.
Solution 16 - Ruby
This could happen when you install new version of ruby and update .ruby-version and Gemfile to the new version without doing install all the gems for new version of ruby first. So do the
$ bundle install
and you might as well need to source .profile or restart your shell.
Solution 17 - Ruby
If you are using rbenv just run
rbenv local 2.0.0
Then
bundle install
Solution 18 - Ruby
Had the same error. Doing the following fixed it. I was using ruby 2.5.5 and rbenv. Upgraded from 2.5.1.
- rbenv rehash
- gem uninstall bundler
- gem install bundler
- gem install bundler:1.17.3 (my app needed specific bundler -v 1.17.3)
- gem install rails
Solution 19 - Ruby
I solved this problem by updating my ruby version to ruby '2.4.0'
Then bundle install
Solution 20 - Ruby
I opened Gemfile and replaced 2.7.1
with my own version of ruby 2.7.0
Everything is okay right now.
Solution 21 - Ruby
Simply closing the terminal I was working on and opening a new one worked for me. Sometimes, updates are not effected immediately until a session is closed. I have found this as the case with many rails errors I faced.
Solution 22 - Ruby
Had the same problem and I'm working with rbenv
Those are the steps that helped me fix my problem:
-
First in terminal, type
which bundle
. For me this gave: /usr/local/bin/bundle
-
Again in terminal try
which ruby
. In my case this gave:/Users/Mahmoud/.rbenv/shims/ruby
The problem here thus is that bundle isn't using the same ruby version from rbenv. So the path needs fixing. In other words I need to tell my terminal to use the rbenv version of bundle when I use bundle install.
So step 3: For me I personally already had the path set in ~/.bash_profile
:
export PATH="$HOME/.rbenv/shims:$PATH"
eval "$(rbenv init -)"
but apparently this was not enough as I was using zsh. Had to add those same 2 lines to ~/.zshrc
as well.
- Restart terminal
Now bundle install
is working as expected and which bundle
gives:
/Users/Mahmoud/.rbenv/shims/bundle
indicating that the problem was just that bundle was using the wrong ruby.
So if you have this problem, just make sure ~/.bash_profile
and ~/.zshrc
have the correct path by adding the 2 lines indicated above. If this didnt work take a deep dive into paths to make sure that before starting which bundle gives the equivalent of:
/Users/Mahmoud/.rbenv/shims/bundle
Solution 23 - Ruby
I face the error msg
Your Ruby version is 2.5.1, but your Gemfile specified 2.3.0
and solved by the following steps:
- open Gemfile which located at your directory.
- change
ruby '2.3.0'
toruby '2.5.1'
and save the Gemfile - go back to items and run bundle update.
the issue is perfectly solved.
