I'm working in kali-linux (a linux distro witch is the continuation of Back-Track, based in Ubuntu, just that now is based on Debian wheezy) for some penetration testing. Everything was working just fine, until I decided to update my systems tools. Now whenever I try to run a tool based on ruby, it trows me:
Could not find gem 'ruby-progressbar (>= 1.1.0) ruby' in the gems available on this machine.
Run `bundle install` to install missing gems.
I proceed to run bundle install but then it comes with Bundler::GemfileNotFound error.
Kali use by default ruby, for using gems. The software don't 'require' any other package but ruby seems not-fully-configured/installed for the problem at hand.
$ ruby --version
ruby 1.9.3p194 (2012-04-20 revision 35410) [i486-linux]
$ rvm
bash: rvm: command not found
$ rbenv
bash: rbenv: command not found

The executables bundle & bundler have the same functionality and therefore can be used interchangeably. You can see in the bundler/exe directory that the bundler executable just loads the bundle executable. It seems to me that the bundle command is more commonly used than the bundler command.
bundle update and bundle install can both install the gems you specified in Gemfile but missing in gems. But bundle update does one thing more to upgrade: If the gems specified in Gemfile don't have version, it will upgrade to whatever latest.
gem env – try to search in provided list under GEM PATHS, in specifications/default. remove there bundler-VERSION. gemspec. install bundler, if you don't have specific: gem install bundler:VERSION --default.
I faced the same problem when I was trying to bundle install without realizing that I was not in the project directory. Make sure you're in the current project directory.
