如何在Gem Bundler中指定小于版本

Question

I'm trying to specify factory_girl_rails version less than 3.0 as I don't have ruby 1.9 installed and 3.0 isn't compatible with 1.8.x. I've tried a few ways round but it always tries to install 3.0.0 and fails on the ruby dependency.

Answer 1

According to this , Rails 3.0 should still be compatible with Ruby 1.8.7 (they aren't dropping Ruby 1.8 support until 4.0).

But, if you put this in your Gemfile, bundler should use the latest 2.3 version (the last minor version before 3.0) of Rails:

gem 'rails', '~>2.3'
