I have a Fedora Core 6 system on which I have built ruby 1.8.6 and
rubygems 1.1.1 from source, and installed rails 2.0.2 using rubygems.
When I create a new rails app, I get lots of errors that look like
they’re coming from internal ruby libraries. Lots of methods
redefined, as if I have some duplicate code somewhere. I also get
errors when generating a simple model (see below.)
I discovered that I did have duplicate installations of rails-2.0.2
under /usr/local/lib/ruby/ and /usr/lib64/ruby/. So, I uninstalled all
the action* gems and rails, which removed them from /usr/local/, and
then manually removed everything under /usr/lib64/ruby/gems/1.8/gems/.
I then reinstalled rails with “gem install rails --include-
dependencies.” Everything went back into /usr/local/lib/ruby. No
obvious errors. Next, I created a new rails app. Whoops! Same errors
as before.
Ideas, please? Also, how can I be sure rails is using the version of
ruby I think it is?
