Bundler: can't find gem bundler (>= 0.a) with executable bundle (Gem::GemNotFoundException) during bundle install with gem

Question

I\'m executing the following script:

gem install rdoc --no-document
gem install bundle
bundle

output:

+ gem install rdoc --         


        

Answer 1

I couldn’t even do bundle -v. This sorted it out:

gem update --system

Got the info from here (similar problem): find_spec_for_exe': can't find gem bundler (>= 0.a) (Gem::GemNotFoundException)

Probably some version mismatch between ruby + gem + bundler
