Ruby: rake:22: undefined method `activate_bin_path' for Gem:Module (NoMethodError)

问题

I had this problems in Ruby 1.8.7-p374.

When try to run "rake db:migrate" i got this error:

RubyGems installed the following executables:
    /home/wellington/.rbenv/versions/1.8.7-p374/bin/gem

RubyGems system software updated
/home/wellington/.rbenv/versions/1.8.7-p374/bin/rake:22: undefined method `activate_bin_path' for Gem:Module (NoMethodError)

Its occurs on deploy Rails apps.

Any ideas to solve this?
