bundler (1.6.2) load 'set' failed on index.rb:1

Question

I'm facing a weird problem on bundler when I was playing around with my rails app.

Env

• ruby 2.1.1
• rails 4.1.0
• bundler 1.6.2

I also tried: ruby 2.0.0, rails 4.0.0. bundle 1.6.0, 1.3.5, none of them works.

What I tried

When I tried rails -v it reports: `require': cannot load such file -- set (LoadError) /bundler-1.6.2/lib/bundler/index.rb:1:in `<top (required)>'

Then I took a look at index.rb, the first line is: require "set"

Then I tried: irb(main):001:0> require 'set' => true irb(main):002:0>

Question

• What's wrong?
• What should I do to recover this?

Answer 1

it turned out that my GEM_HOME and GEM_PATH had some problem, I tried to use this rbenv at that moment, but later, I switched to raw installation. And it worked.
