I have rails project working on Ubuntu.
Now I installed WSL on another machine and cloned the very same project.
Now when I try to install bundler with
gem install bundler
it installed bundler 2.0.2 and on bundle install it gives error:
Could not find gem 'bundler (< 2.0, >= 1.3.0)', which is required by gem 'rails (~> 5.0.0)'
Now I looked at the gemfile.lock it was bundled with 1.16.4, I installed it with
gem install bundler -v '1.16.4'
Now I do a simple bundle install, then it uses 2.0.2, so I have to do
bundle _1.16.4_ install
It completed successfully, but now when I am trying to do rails db:create, it says
The git source https://github.com/activerecord-hackery/ransack.git is not yet checked out. Please run bundle install before trying to start your application
What's wrong here?
Uninstall bundler 2.0.2:
gem uninstall bundler -v 2.0.2
If you still have problem, you can use:
bundle exec rails db:create
You can update to using bundler 2.x if possible with:
bundle update --bundler
This will change the BUNDLED_WITH version in Gemfile.lock.
see: https://bundler.io/guides/bundler_2_upgrade.html
You could also set the default bundler version:
bundler config default 1.16.4
gem list bundler
However I have found this to be a bit error prone.
Try to remove all your gems (go to the gems folder of your ruby, remove the specifications folder and the gems folder),
gem list should be more or less empty
gem install bundler
And try to bundle install again from scratch.
I'm working with heroku and every time I try to push my app this message shows out:

But my Bundler version is 2.0.0.pre.1
Don't know what to do, I tried uninstalling bundle and installing it again, I errased the Gemfile.lock and typing bundle again
I had a similar experience.
Here's how I solved it
Display a list of all your local gems for the bundler gem
gem list bundler
N/B: The command above is for rbenv version manager, the one for rvm might be different
This will display the versions of the bundler gem installed locally
bundler (2.1.4, default: 1.17.2)
Note: Your versions might differ from the one here
if you don't have bundler version 2 installed locally, then run
gem install bundler
OR
gem install bundler -v 2.1.4
Note: Replace 2.1.4 with the version you want to install
if you have bundler version 2 already installed locally or just installed it, then you need to simply install an update for RubyGems Package Manager locally. To do this, run
gem update --system
And then finally run
bundle update --bundler
For Docker projects in Ruby on Rails
If you're experiencing this issue when trying to build your application using Docker, simply do this:
Delete the Gemfile.lock file
Please don't create it again by running bundle install.
Run your docker build or docker-compose build command as appropriate to build your project.
This will re-create the Gemfile.lock file and setup the appropriate version of bundler necessary for your project in the Gemfile.lock file.
N/B: As a side note, you can also add this environment variable to your Dockerfile with the Bundler version defined.
ENV BUNDLER_VERSION=2.1.4
A bit late to the party but I just ran into this today as well, and this solution avoids having to uninstall Bundler: just run
heroku buildpacks:set https://github.com/bundler/heroku-buildpack-bundler2
as per discussion on the Bundler issue here.
I had same issue on Local Machine(Development) as-
You must use Bundler 2 or greater with this lockfile.
The issue was with gemfile.lock because my local bundle version and project bundle version was not matching!
Here is solution-
I deleted gemfile.lock
Run the command - bundle install
That solved my problem, it is smooth!
Hope will work for others!
simple gem update bundler did it for me.
I resolved this issue by running gem uninstall bundler to remove 2.0.0.pre.1, renamed the Gemfile.lock file (to remove it from use) and then ran bundle install to reinstall the gemfiles. In my case, I already had access to the earlier bundler version installed by heroku (so when I ran gem uninstall, I was shown all versions available and chose to remove 2.0.0.pre.1).
Even with bundler 2 on the system this error still happens when deploying an app with Ruby 2.6 since Ruby 2.6 ships with a default version of bundler.
If you are using Ruby 2.6 then upgrade to Ruby 2.6.1 to avoid this issue.
The Ruby 2.6.0 is not the case of this problem.
The default version of Bundler incorrectly invoked when using bin stubs.
For more details please refer the following link
Solution:
Bundler 2 is available on the system and is the latest version, So it should be invoked instead of the default bundler version.
Update Rubygems
gem update --system
Update bundler
gem install bundler
Update Gemfile.lock in your project
bundler update --bundler
Yup, so generally uninstalling your version of bundler, removing the gemfile.lock, and finally running gem install bundler -v 1.15.2(which is the version heroku is using) worked.
After that running git push heroku master worked!
For local system
gem install bundler:2.0.0.pre.1
bundle _2.0.0.pre.1_ install
Where "2.0.0.pre.1" is whatever version you need to bundle with.
Don't delete your Gemfile.lock for this, it's there for a reason.
If you're using a docker image like FROM:ruby:2.X.X then you can do the following:
FROM ruby:2.6.2
... # omitted
COPY Gemfile /myapp/Gemfile
COPY Gemfile.lock /myapp/Gemfile.lock
RUN gem uninstall bundler
RUN gem install bundler -v 2.1.4
RUN bundle update --bundler
RUN bundle install
... # omitted
Heroku does not use Bundler 2.0, but 1.15.2, as the tracelog hints.
As far as I am aware, the "workaround" is to create your own buildpack, or simple fork their own:
Open lib/language_pack/ruby.rb in your editor, and change the following line:
BUNDLER_VERSION = "1.11.2"
(README.md at https://github.com/heroku/heroku-buildpack-ruby)
Update: As of Ruby 2.6.1 and Bundler 2.0.1, Heroku now does support Bundler 2.0.1. https://devcenter.heroku.com/articles/bundler-version#known-upgrade-issues
This is not the case for Ruby 2.6.0, as this is incorrectly invoked from binstubs, as #Schneems has mentioned in the comment. He has kindly reported this as a Ruby Bug #15622
For people who are not using Heroku:
I Tried everything and I was still receiving this error. even this link didn't help me: https://github.com/jekyll/jekyll/issues/7463
So this was my solution:
Push your code on GitHub.
delete project folder
create a new folder and pull your code
bundle install
That's it. bundler update --bundler was not helping me at the end and I didn't use it.
One more important thing:
I updated my ruby version but I was getting this error because my RVM default version was an old version.
even when you use rvm use VERSION_NUMBER -- default will not help because as soon as you log out from terminal the default version will change to the old one and you will have the same issue.
For this you can use this answer:
How to set default Ruby version with RVM?
or just uninstall old ruby version with rvm uninstall X.X.X and install the new one with rvm install X.X.X and make it default by rvm use --default X.X.X.
cheers.
I got the same problem for Ruby 2.6.3, nothing listed in answers could help.
The only the following solution worked for me:
bundle update rails
Remove Gemfile.lock
bundle
I had the same issue. In my Gemfile.lock i saw at the end "bundled with bundler 2.0.2", but running bundle --version gave me version 1.17... For me it solved just updateing my bundler with the following command: bundle update --bundler see bundler documentation
I deleted the project and made a git clone from the Heroku app, don´t know if it is a good solution, but it worked for me.
I got the same issue in my local system, my ruby version was low due to which the error was occurring. Fixed it by switching it to updated versions of ruby.
Using bundler 2.0.1 allows for automatic version switching as required by the lock file. In this regard, installing bundler 2.0.1 worked for me.
Installing bundler 2.0.1
gem install bundler -v 2.0.1
Update bundler
bundle update -bundler
I had the same problem today.
In my case the problem was caused by using rvm gemset other than latest I have with ruby 2.7.1 and bundler 2.1.4 (same bundle Gemfile was locked with).
So just take a look at your rvm environment before doing any other solution listed here. Specially if you're running your project on production.
Happy hacks !
Delete gem history and modules installed in rails application.
$ rm -rf vendor/bundle
$ rm Gemfile.lock
and, bundle
$ bundle install --path=vendor/bundle
and, start Rails Server
$ bundle exec rails s
and, connect to browser.
http://localhost:3000/
Same error, but locally.
I finally figured out I was using wrong version of ruby on my command line (I'm using uru to manage ruby versions.)
After all, how could the gemfile use and produce a lock file with version 2.1.4, yet my search didn't find that version!
>gem list bundler
*** LOCAL GEMS ***
bundler (default: 1.16.2, 1.13.1)
capistrano-bundler (1.6.0, 1.1.4)
So I changed to the correct version of ruby and all was good.
Remember, gems are stored with your Ruby version!
I am trying to install bundler using ruby gems and RVM, but I am running into this error when I run the bundle init command:
/Library/Ruby/Site/2.0.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'bundler' (>= 0) among 13 total gem(s) (Gem::LoadError)

from /Users/CalebKleveter/.gem/ruby/2.0.0/bin/bundle:22:in `<main>'
I am installing it using this command:
gem install --user-install bundler
I was having issues before when downloading bundler. I was getting this error:
WARNING: You don't have /Users/CalebKleveter/.gem/ruby/2.2.0/bin in your PATH,
gem executables will not run.
So I ran this command to fix it:
PATH=$PATH:/Users/CalebKleveter/.gem/ruby/2.2.0/bin export PATH
Am I installing it in the wrong spot?
All gems were working earlier, but I ran this command:
rvm use 2.2.3
So I am using ruby version 2.2.3, I was using version 2.0.0 before if I remember correctly. Is that the issue?
It's not an issue per se, but you might find incompatibilities between old gems and current version of rails.
Run rvm list and then set the default to the latest version of rails and update your gems.
I am new to ruby on rails and trying to install the bundle in my rails app and getting the same error this whole time ..
Bundler could not find compatible versions for gem "bundler":
In Gemfile:
bundler (= 1.0.18) ruby
Current Bundler version:
bundler (1.7.4)
This Gemfile requires a different version of Bundler.
Perhaps you need to update Bundler by running gem install bundler?
I have tried almost each suggestions that've been suggested but none so far worked for me.
Can anybody help..??
Thank you in advance..
Usually, Bundler does not need to be on Gemfile.
You can remove the line that contains bundler in Gemfile, then run bundle again.
The reason this is failing is because your system has probably a newer version of bundler than the Gemfile is asking for.
I've been getting this error after installing rvm and rails with rvm. Can anyone help me out?
/Library/Ruby/Site/1.8/rubygems.rb:779:in report_activate_error': Could not find RubyGem rails (>= 0) (Gem::LoadError) from /Library/Ruby/Site/1.8/rubygems.rb:214:in activate' from /Library/Ruby/Site/1.8/rubygems.rb:1082:in `gem' from /usr/bin/rails:18
Thanks!
Couple of things to look at:
Make sure Rails is indeed installed. I'm bringing up this point because you mentioned that you installed Rails with RVM, which is inaccurate. You install Rubies with RVM but you install Rails with Bundler (you can see Bundler as an RVM for gems rather than rubies). So ensure that you have a line that says gem 'rails' in your Gemfile and then run bundle install.
As pointed out by other answers, make sure you are using the right ruby and gemset (where you installed the Rails gem). To do so run rvm use <your_ruby>#<your_gemset>.
Are you sure you're actually in the RVM Ruby right now? I often hit this error when I forget to enter rvm use MY_RUBY_VERSION. It's looking for the rails gem, but can't find it.
