I have been studying rspec the last week or two and have been using Rail 2.1.2 to do my exploring. I was finally ready to jump into some legacy code and couldn’t even create a spec folder on the directory tree because the version of rails was older:
1: user$ ruby script/generate rspec2: Cannot find gem for Rails ~>22.214.171.124:3: Install the missing gem with 'gem install -v=1.2.3 rails', or4: change environment.rb to define RAILS_GEM_VERSION with your desired version.
After looking at the rails file in /usr/bin, I noticed the regex was looking for something that matched the following regex string:1: /^_(.*)_$/
If my recollection holds, that means I’m looking for any character set that begins and ends with underscores (i.e., _1.x.x).
So I tried the following:1: rails _1.2.3_ <projectname>
and it succeeded.
Hope this helps someone else. Continuing my Ruby journey.
I’m also looking at Fluent NHibernate now, so it’s going to be a few couple weeks.
