Q:

"Could not find bundler" error

When I try to do bundler update I get this error:
.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in
`to_specs': Could not find bundler (>= 0) amongst
[rake-0.8.7, rake-0.8.7, rubygems-update-1.8.4] (Gem::LoadError)

I'm new to Ruby, can someone tell me what would cause this? Rake 0.8.7 is installed.

A:

Make sure you're entering "bundle" update, if you have the bundler gem installed.
bundle update
If you don't have bundler installed, do gem install bundler.

A:

I had this problem, then I did:
gem install bundle

notice "bundle" not "bundler" solved my problem.
then in your project folder do:
bundle install

and then you can run your project using: 
script/rails server

A:

I had the same problem. This worked for me:

run rvm/script/rvm and also add it to your .profile or .bash_profile as shown in https://rvm.io/rvm/install/
use bundle without sudo
