Play-by-Play: Ruby, Rails, and Heroku Versions

First, update to macports 1.8.2.

Ruby Update

sudo port install ruby

I’m going to get 1.8.7 p249

• p249 “has marshaling bugs that crash Rails 3.0.0“
• Get RVM to help manage the versions.

  bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
  if [[ -s "$HOME/.rvm/scripts/rvm" ]]  ; then source "$HOME/.rvm/scripts/rvm" ; fi
  source ~/.rvm/scripts/rvm
  rvm notes
  

  Add to .profile:

  for profile in .bash_profile .bashrc ; do echo 'if [[ -s "$HOME/.rvm/scripts/rvm" ]]  ; then source "$HOME/.rvm/scripts/rvm" ; fi' >> $HOME/$profile done
  

  Is this necessary? Should it be in .bash_profile? (Probably not as it references .bash_profile). I’m still fairly new to UNIX and so don’t know my profile consequences off by heart.

I’m not going to get into ruby 1.9 as Rails 3 isn’t stable on 1.9.1 (1.9.2 only) and Heroku only supports 1.9.1.

Rails 3

I’m preferring Rails 3 as:

• It’s definitely the way of the future.
  • There’s quite a few new APIs — meaning old ones will be abandoned. Rails doesn’t sit still.
  • The API appears to be improved all the way around; it’s more fun to use.
• It should be stable & released by the time I’m ready to launch.

But which ruby version should I be using? All seem to have potential for issues. I’ll run 1.8.7@249 and see if it works.

Rubygems

RubyGems update, attempt 1:

 gem update --system
 Updating RubyGems
 /opt/local/lib/ruby/site_ruby/1.8/rubygems/spec_fetcher.rb:245: [BUG] Segmentation fault
 ruby 1.8.7 (2010-01-10 patchlevel 249) [i686-darwin9]
Abort trap

I didn’t sudo, and it gave me a segfault instead of a real error
Attempt #2, this time with sudo:

 sudo gem update --system

File not found: lib

Found the issue here. How did we ever develop software before Google?
This might not be a big deal after all.

Heroku

I’m going to try Heroku for deployment/hosting.
First, I need Bundler:

sudo gem install bundler
/opt/local/lib/ruby/site_ruby/1.8/rubygems/spec_fetcher.rb:254: warning: getc is obsolete; use STDIN.getc instead

I hate warnings.

Next is the Heroku gem:

sudo gem install heroku

Time to read up on the Heroku quickstart.
