The reason is your current ruby environment  you got a different version of bundler with the version in Gemfile lock    Safe way  install bundler with the same version in Gemfile lock  this won t break anything if there is some incampatibly thing happened  Hard way  just remove Gemfile lock  and run bundle install

I had the same issue today  I solve this problem by removing any PATH in  bashrc for older rvm

The real answer is here if you try to install bundler 2 0 1 or 2 0 0 due to Bundler requiring RubyGems v3 0 0  Yesterday I released Bundler 2 0 that introduced a number of breaking changes  One of the those changes was setting Bundler to require RubyGems v3 0 0  After making the release  it has become clear that lots of our users are running into issues with Bundler 2 requiring a really new version of RubyGems  We have been listening closely to feedback from users and have decided to relax the RubyGems requirement to v2 5 0 at minimum  We have released a new Bundler version  v2 0 1  that adjusts this requirement   For more info  see  https   bundler io blog 2019 01 04 an-update-on-the-bundler-2-release html

to install bundler that matches with your Gemfile lock use   gem install bundler -v    grep -A 1  BUNDLED WITH  Gemfile lock   tail -n 1

Adding to the many answers  my problem stemmed from wanting to use the docker s ruby as a base  but then using rbenv on top  This screws up a lot of things   I fixed it in this case by    The Gemfile lock version did need updating - changing the  BUNDLED WITH  to the latest version did at one point change the error message  so may have been required in  bash profile or  bashrc  unsetting the environment variables    unset GEM HOME unset BUNDLE PATH   After that  rbenv worked fine  Not sure how those env vars were getting loaded in the first place

Open Gemfile lock  which is to be found in the root of your app folder  Scroll to the end of the file and see the bundler version used  Then you make sure you install the bundler version used    gem install bundler -v x xx xx   Or - delete the Gemfile lock and bundle if you have higher bundler version installed    The choice is yours  my friend

If you changed the ruby version you re using with rvm use  remove Gemfile lock and try again

Update  According  noraj s answer and  Niels Kristian s comment  the following command should do the job  gem update --system bundle install   I wrote this in case someone gets into an issue like mine  gem install bundler shows that everythings installs well  Fetching  bundler-1 16 0 gem  100   Successfully installed bundler-1 16 0 Parsing documentation for bundler-1 16 0 Installing ri documentation for bundler-1 16 0 Done installing documentation for bundler after 7 seconds 1 gem installed  When I typed bundle there was an error   Users nikkov  rvm gems ruby-2 4 0 bin bundle 23 in  load   cannot load such file --  Users nikkov  rvm rubies ruby-2 4 0 lib ruby gems 2 4 0 gems bundler-1 16 0 exe bundle  LoadError      from  Users nikkov  rvm gems ruby-2 4 0 bin bundle 23 in   lt main gt       from  Users nikkov  rvm gems ruby-2 4 0 bin ruby executable hooks 15 in  eval      from  Users nikkov  rvm gems ruby-2 4 0 bin ruby executable hooks 15 in   lt main gt    And in the folder  Users nikkov  rvm rubies ruby-2 4 0 lib ruby gems 2 4 0 gems  there wasn t a bundler-1 16 0 folder  I fixed this with sudo gem install bundler

User · Answer

The problem in my case is that the Gemfile lock file had a BUNDLED WITH version of 1 16 1 and gem install bundler installed version 2 0 1  so there was a version mismatch when looking to right the folder  gem install bundler -v 1 16 1 fixed it  Of course  you can also change your Gemfile lock s BUNDLED WITH with last bundler version and use recent software  as Sam3000 suggests

In my case the above suggestions did not work for me  Mine was little different scenario   When i tried installing bundler using gem install bundler    But i was getting   ERROR   While executing gem      Gem  FilePermissionError      You don t have write permissions for the  Library Ruby Gems 2 3 0 directory    then i tried using sudo gem install bundler then i was getting   ERROR   While executing gem      Gem  FilePermissionError    You don t have write permissions for the  usr bin directory    then i tried with sudo gem install bundler -n  usr local bin   Just  usr bin dint work in my case     And then successfully installed bundler  EDIT  I use MacOS  maybe  usr bin din t work for me for that reason  https   stackoverflow com a 34989655 3786657 comment
