find_spec_for_exe': can't find gem bundler (>= 0.a) (Gem::GemNotFoundException)

Question

I used sudo bundle install and that might be the cause of the issue?

Now I have:

• gem -v 2.6.14
• ruby -v ruby 2.3.5p376 (2017-09-14 revision 59905) [x86_64-darwin15]
• jekyll -v jekyll 3.6.2
• bundle -vBundler version 1.16.0.pre.3

I'm getting the following error when trying to run bundle exec jekyll serve or just jekyll serve

/Users/myusername/.rvm/rubies/ruby-2.3.5/lib/ruby/site_ruby/2.3.0/rubygems.rb:271:in `find_spec_for_exe': can't find gem bundler (>= 0.a) (Gem::GemNotFoundException)

Also, when accessing the folder in which I have my blog cd my_path I get the following message:

VM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too, you can ignore these warnings with 'rvm rvmrc warning ignore /Library/WebServer/Documents/blog/Gemfile'. To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'. Unknown ruby interpreter version (do not know how to handle): RUBY_VERSION.

I've no idea how to solve this. I just want to create my static blog and honestly I have no idea about Ruby, Gem or Bundle :) So I would appreciate some insights!

Answer 1

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
