1.9.3 installed, error message factory_girl requires Ruby version >= 1.9.2

问题

I just installed rbenv with ruby 1.9.3

rbenv version
1.9.3-p327 (set by /Users/me/.rbenv/version)

However, when I tried to run bundle update (inside a project that was created before rbenv was installed), I got an error message that factory_girl required at least ruby 1.9.2. See error message below

If it's relevant, when I do gem --version, I see a reference to 1.8.23.

gem --version
1.8.23

Error message

Update:

The first answer told me to do three steps

gem install bundle
rbenv rehash
bundle install

I did those steps (it installed bundler) '

gem install bundler
Fetching: bundler-1.2.3.gem (100%)
Successfully installed bundler-1.2.3
1 gem installed

but when I tried 'bundle install, I got the same error message about Factory_girl. Interestingly, I decided to try those three steps again, beginning with gem install bunlder, and it installed it again?!#??

回答1:

The bundle command you are using is from system Ruby installation which is Ruby 1.8.x.

Try

gem install bundler
rbenv rehash
bundle install

This should solve your problem.
