Cannot run `bundle install`

Question

So the other day I ran into an extreme hard disk issue and had to manually delete my .gem folder. I attempted to rebuild the gems for my apps by going into my project folders to run bundle install ... I am unfortunately running into this error:

/home/xxx/.rvm/rubies/ruby-2.2.2/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- bundler (LoadError)
    from /home/xxx/.rvm/rubies/ruby-2.2.2/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from /usr/bin/bundle:7:in `<main>'

By the way, line 54 of kernel_require.rb is return gem_original_require(path):

if Gem::Specification.unresolved_deps.empty? then
  RUBYGEMS_ACTIVATION_MONITOR.exit
  return gem_original_require(path)
end

Answer 1

Since you deleted the ".gem" folder, your Bundler gem is also not present.

Try reinstalling the Bundler gem first by using

gem install bundler

then you can run

bundle install
