Ruby Forum Ruby on Rails > "File not found: lib" installing rails-3.0.0.beta3 on my Mac

I've always distrusted the ruby and rails installs on my Mac (oOS X
10.6.3) -- sudo gem cleanup can't seem to get rid of old gem versions
(lots of Gem::InstallError: cannot uninstall).

Because of that, I don't trust the rails beta3 install I just
completed.  Here's the story:

* config is Apple's ruby 1.8.7 and gem 1.3.6.
* xcode is installed from Apple's developer site.
* gem env result is:

RubyGems Environment:
  - RUBYGEMS VERSION: 1.3.6
  - RUBY VERSION: 1.8.7 (2009-06-08 patchlevel 173) [universal-
darwin10.0]
  - INSTALLATION DIRECTORY: /Library/Ruby/Gems/1.8
  - RUBY EXECUTABLE: /System/Library/Frameworks/Ruby.framework/
Versions/1.8/usr/bin/ruby
  - EXECUTABLE DIRECTORY: /usr/bin
  - RUBYGEMS PLATFORMS:
    - ruby
    - universal-darwin-10
  - GEM PATHS:
     - /Library/Ruby/Gems/1.8
     - /Users/burleigh/.gem/ruby/1.8
     - /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/
ruby/gems/1.8
  - GEM CONFIGURATION:
     - :update_sources => true
     - :verbose => true
     - :benchmark => false
     - :backtrace => false
     - :bulk_threshold => 1000
  - REMOTE SOURCES:
     - http://rubygems.org/

I have done these commands:

sudo gem update --system
sudo gem cleanup

sudo gem install tzinfo builder i18n memcache-client rack \
  rake rack-test rack-mount erubis mail text-format \
  thor bundler
sodu gem install rails --pre

whose execution ends with:

Installing ri documentation for rails-3.0.0.beta3...
File not found: lib

The gems/rails-3.0.0.beta3 directory has a bin directory with a 20
character file named "rails."  The other gem directories seem fuller.

That, combined with the failure of gem cleanup, makes me think "this
can't be right."

I'd appreciate any advice how I might clean up my Mac rails
environment.

Thank you.

PS: I have so far avoided MacPorts.

I built and installed my own ruby and rubygems, leaving the Apple-
provided installations alone.  I used ruby 1.9.1 and gems 1.3.6.

Then I followed the procure outlined to install the gems, then rails
beta3 itself.  Again I got the complaint about the missing lib
directory. I followed common advice to create the lib directory in .../
gems/rails-3.0.0.beta3, then installed the rails gem once again -- to
successful completion.  There's nothing actually *in* the lib
directory -- I can only hope that's as it should be.  There are enough
references to this problem that I'll assume there's either some
dependance or some packaging issue, and that the Rails team has it on
their radar for a fix.

I'm having the identical problem with beta4.

I am having this same problem, but I am using Ruby 1.8.7 and an
updated version of RubyGems. Does anyone have an answer for this
issue? I know that Rails 3 does not work at all with 1.9.1, so I tried
1.9.2 and it did not seem to work either. So I decided to go with the
older version.

Is there an update on this problem?

I'm seeing the same problem:

[root@******* ruby-enterprise-1.8.7-2010.02]# gem install rails 
--prerelease
Successfully installed rails-3.0.0.beta4
1 gem installed
Installing ri documentation for rails-3.0.0.beta4...
File not found: lib

I have upgraded Ruby to version 1.8.7.

Can anyone help me with this?

Thank you.

Are you using RVM by any chance? If you are, you cannot use 'sudo' when
installing the gems. I had this issue at first (kept saying File not
found: lib) and then I noticed that RVM installs things as you, not as
sudo. Therefore I just used the command:

'gem install rails --pre' or just 'gem install rails' (since Rails 3 has
been released)

and I got rid of the 'File not found: lib' issue. Hope this helps.

I've noticed this distrust in a lot of people.  Can't see any reason for 
it myself.  Apple's Ruby has always worked fine for me.  I'll be 
installing 1.9.2 and RVM at some point, but until then I'll save my 
effort and disk space and not build my own Ruby.  If that costs me geek 
brownie points, so be it. :D.

Never seen that.  Find and fix the problem instead of just "distrusting" 
your development environment.

Again: Apple's Ruby is perfectly trustworthy.  If it's not working for 
you, the problem is most likely elsewhere (perhaps a reinstallation of 
Apple's dev tools is in order...).

Sorry, neglected to notice I was replying to an oldish post.
