gem cleanup and rails 1.2.6 problem

I've updated rails and other gems following: http://wiki.rubyonrails.org/rails/pages/HowtoUpgrade When I try to run: gem cleanup, I get the following error:

Cleaning up installed gems... Attempting to uninstall rails-1.2.6 ERROR: While executing gem ... (Gem::InstallError)     Unknown gem rails = 1.2.6

Googling the problem, I found: Problem with "gem cleanup" on OS X 10.5 - Ruby - Ruby-Forum Running: gem uninstall --install-dir -/System/Library/Frameworks/Ruby.framework/ Versions/1.8/usr/lib/ruby/gems/1.8 rails

I get: ERROR: While executing gem ... (Gem::InstallError)     Unknown gem rails >= 0

How can I uninstall rails 1.2.6? also, since gem cleanup gets an error, I can't clean up any other gems....

Become root, and then do it this way:

gem uninstall --install-dir /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8 rails

Running it with sudo I get:

ERROR: While executing gem ... (Gem::InstallError)     Unknown gem rails >= 0

Do I need to actually sign in as root?

You should be OK with sudo. Can you post your exact command line, and the output from gem list -d rails

gem list -d rails gives me:

*** LOCAL GEMS ***

rails (2.2.2, 1.2.6)     Author: David Heinemeier Hansson     Rubyforge: http://rubyforge.org/projects/rails     Homepage: http://www.rubyonrails.org     Installed at (2.2.2): /Library/Ruby/Gems/1.8                  (1.2.6): /System/Library/Frameworks/Ruby.framework/ Versions/1.8/usr/lib/ruby/gems/1.8

    Web-application framework with template engine, control-flow layer,     and ORM.

Then running: sudo gem uninstall --install-dir -/System/Library/Frameworks/ Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8 rails gives me:

ERROR: While executing gem ... (Gem::InstallError)     Unknown gem rails >= 0

The problem is with your path. You want /System/Library…

but you are doing -/System/Library…

See the difference?

Ah...this is a good topic. I'm new to Ruby while using the Mac. So it seems that Mac's installed Ruby can be uninstalled properly as well. Then we can definitely update it to get the latest version.

Thanks Charles.

Sorry for the late reply -- for some reason missed your post till now. Running the command with the correct path and sudo, asks me if I want to remove executables: rails in addition to the gem? [Yn] When I say y, I get an error: ERROR: While executing gem ... (Gem::FilePermissionError)     You don't have write permissions into the /System/Library/ Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/bin directory.

Should I sign in as root?

Cheers, Elle

Yes, please sign in as root, and be sure you get the path right: is starts /System… but not -/System…

Signed in as root and made sure I have the correct path and the same happens. It asks if I want to uninstall rails. I say yes and it gives me an error: ERROR: While executing gem ... (Gem::FilePermissionError)     You don't have write permissions into the /System/Library/ Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/bin directory.

Why is this happening? What should I do?

Thanks, Elle

Log in as root, and go to /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8/bin

and post the owner, group and permissions on one of the files. Also post the output of “whoami” command.

Thanks.

Logged as root, went to /System/Library/Frameworks/Ruby.framework/ Versions/1.8/usr/lib/ruby/gems/1.8 Running % whoami gives me: root

Then running % ls -l gives me: total 8 drwxr-xr-x 31 root wheel 1054 31 Oct 16:51 cache drwxr-xr-x 32 root wheel 1088 31 Oct 16:51 doc drwxr-xr-x 31 root wheel 1054 31 Oct 16:51 gems -rw-r--r-- 1 root wheel 4 5 Jan 2008 source_cache drwxr-xr-x 31 root wheel 1054 31 Oct 16:51 specifications
