I’ve spent half the day so far inbeded in the furious stressful upgrade process of a handful of Ubuntu Linux 10.04 and Mac OS X Snow Leopard systems from Ruby 1.9.1 to Ruby 1.9.2. I haven’t even gotten to the Rails 3.0.0 stuff yet: just the baseline Ruby installation. I’ve gone through the upgrade process on both types of systems so far and the base issues have been the same. Here’s a common issue that many people are running into:
/opt/local/lib/ruby1.9/site_ruby/1.9.1/rubygems/source_index.rb:68:in `installed_spec_directories': undefined method `path’ for Gem:Module (NoMethodError)
from /opt/local/lib/ruby1.9/site_ruby/1.9.1/rubygems/source_index.rb:58:in `from_installed_gems’
from /opt/local/lib/ruby1.9/site_ruby/1.9.1/rubygems.rb:883:in `source_index’
from /opt/local/lib/ruby1.9/site_ruby/1.9.1/rubygems/gem_path_searcher.rb:81:in `init_gemspecs’
from /opt/local/lib/ruby1.9/site_ruby/1.9.1/rubygems/gem_path_searcher.rb:13:in `initialize’
from /opt/local/lib/ruby1.9/site_ruby/1.9.1/rubygems.rb:841:in `new’
from /opt/local/lib/ruby1.9/site_ruby/1.9.1/rubygems.rb:841:in `block in searcher’
from <internal:prelude>:10:in `synchronize’
<…and so on…>
Assuming you’re upgrading from a previous Ruby installation, note that the “site_ruby” directories are no longer used, and will eff up your 1.9.2 installation if you fail to delete them after the install. On OS X, run:
sudo rm -rf /opt/local/lib/ruby1.9/site_ruby/
On Ubuntu Linux 10.04, run:
rm -rf /usr/local/lib/ruby/site_ruby/
…to correct this issue. All note that you may see errors such as this:
root@li92-132:~# rake –version
/usr/local/lib/ruby/1.9.1/rubygems.rb:340:in `bin_path': can’t find executable rake for rake-0.8.7 (Gem::Exception)
from /usr/local/bin/rake:19:in `<main>’
The standard library is installed in /usr/local/lib/ruby/1.9.1This version number is “library compatibility version”. Ruby 1.9.2 is mostly compatible with the 1.9.1, so its library is installed in the directory.
- Just to keep things clean, you may also want to remove your old Ruby 1.8.x builds. (I recommend doing so unless you have older apps that haven’t moved to 1.9.x yet.)
- Phusion Passenger seems to work fine on Ubuntu 10.04 with the latest version of Apache 2 as of this writing, though don’t forget to recompile, reinstall, reconfigure and restart apache2 when you do so.
- Check if you still need rack v1.0.1 installed (for older Rails app) before nuking everything.
