I am trying to add the carrierwave gem. Once I put it into my gemfile and run bundle install, I receive this message on the command prompt telling me the bundler could not find compatible versions of bundler. I understand there is already many people out there which have asked the same sort of question, however after trying solutions such as deleting gemfile.lock or running bundle update, it still doesn't seem to be working.

After trying different solutions I am getting the same error as shown on the image.

Any help would be appreciated!

Gemfile:

Error after running "Bundle Install" Image of error

EDIT:

After trying Mismatched bundler version - bundler 2, ruby 2.6 , i received the following error:

Edit Error after running bundle binstubs bundler

SOLVED:

Removed 

bundler (>= 1.3.0, < 2.0)

from the gemfile.lock and ran bundle install.

  • You should share exactly what you have tried. You should show the exact steps you take and the exact error message you get. –  Feb 01 '19 at 18:32
  • Hard to tell without details of your error, but is it this? https://stackoverflow.com/questions/54123850/mismatched-bundler-version-bundler-2-ruby-2-6/54125881 – Dave Slutzkin Feb 01 '19 at 18:55
  • The error is telling you what the problem is. That version of bundler isn't compatible. Do gem install bundler -v 1.17.3 – Paul Byrne Feb 01 '19 at 19:04
  • @PaulByrne that did not work. I am receiving the same error on cmd – Krupa Feb 01 '19 at 19:13
