How to Install Berkshelf version3 on Cygwin 64bit

Installation of Berkshelf v3 on Cygwin is known to be very diffcult, but I have finally found the way. 😄

You can successfully install it by following the procedure below.

(As at 2014/6/8, v3.1.3 is available)

Why is it so difficult ?

RSpec.configure do |config|

    example = RSpec.current_example
    CAPYBARA_TIMEOUT_RETRIES.times do |i|
      example.instance_variable_set('@exception', nil)
      self.instance_variable_set('@__memoized', nil) # clear let variables

Jim Weirich:

This is how I explain it… Ruby has Procs and Lambdas. Procs are created with Proc.new { }, lambdas are created with lambda {} and ->() {}.

In Ruby 1.8, proc {} creates lambda, and Ruby 1.9 it creates procs (don't ask).

Lambdas use method semantics when handling parameters, procs use assignment semantics when handling parameters.

This means lambdas, like methods, will raise an ArgumentError when called with fewer arguments than they were defined with. Procs will simply assign nil to variables for arguments that were not passed in.
