uninitialized constant ActiveSupport::Cache (NameError)

Hi

After having updated some GEMS I get `load_missing_constant': uninitialized constant ActiveSupport::Cache (NameError) on starting the server of a freshly generated rails project.

Before, I already had Rails 2.3.2 projects succesfully running, now all of them generate this error.

These are my GEMS: actionmailer (2.3.2, 2.2.2, 2.1.2, 2.1.1, 2.1.0) actionpack (2.3.2, 2.2.2, 2.1.2, 2.1.1, 2.1.0) activerecord (2.3.2, 2.2.2, 2.1.2, 2.1.1, 2.1.0) activeresource (2.3.2, 2.2.2, 2.1.2, 2.1.1, 2.1.0) activesupport (2.3.2, 2.2.2, 2.1.2, 2.1.1, 2.1.0) bones (2.5.1, 2.5.0, 2.4.2, 2.4.0, 2.3.1, 2.1.1) capistrano (2.5.5, 2.5.3, 2.5.2, 2.5.0) cgi_multipart_eof_fix (2.5.0) columnize (0.3.0, 0.2) daemons (1.0.10) fastthread (1.0.1) fxri (0.3.7) fxruby (1.6.19, 1.6.18, 1.6.17, 1.6.16) gem_plugin (0.2.3) highline (1.5.1, 1.5.0, 1.4.0) hoe (2.0.0, 1.12.2, 1.11.0, 1.8.3, 1.8.2, 1.8.0) htmlentities (4.0.0) linecache (0.43) log4r (1.0.5) mini_magick (1.2.5, 1.2.3) mongrel (1.1.5) mongrel_cluster (1.0.5) mongrel_service (0.3.4) mysql (2.7.3) needle (1.3.0) net-scp (1.0.2, 1.0.1) net-sftp (2.0.2, 2.0.1) net-ssh (2.0.11, 2.0.9, 2.0.8, 2.0.6, 2.0.4) net-ssh-gateway (1.0.1, 1.0.0) newgem (1.4.1, 1.3.0, 1.2.3, 1.2.1, 1.2.0) ptools (1.1.6) rails (2.3.2, 2.2.2, 2.1.2, 2.1.1) rake (0.8.7, 0.8.4, 0.8.3) rcov (0.8.1.2.0) RedCloth (4.1.9, 4.1.1) restfulx (1.2.2, 1.2.1, 1.2.0) rmagick (2.9.0) rubigen (1.5.2, 1.4.0) ruby-debug (0.10.3, 0.10.2) ruby-debug-base (0.10.3, 0.10.2) ruby-debug-ide (0.4.6, 0.4.5, 0.4.4, 0.4.3, 0.4.2, 0.3.1) ruby-prof (0.7.3, 0.7.1, 0.7.0, 0.6.0) rubyforge (1.0.3, 1.0.2, 1.0.1, 1.0.0) rubygems-update (1.3.4, 1.3.3, 1.3.1, 1.3.0) rubyist-aasm (2.0.5, 2.0.4, 2.0.2) sources (0.0.1) sqlite3-ruby (1.2.1) syntax (1.0.0) test-unit (2.0.2, 2.0.1, 2.0.0) win32-api (1.4.2, 1.4.0, 1.3.0, 1.2.2, 1.2.1, 1.2.0) win32-clipboard (0.5.1, 0.4.4) win32-dir (0.3.4, 0.3.3, 0.3.2) win32-eventlog (0.5.0) win32-file (0.6.1, 0.6.0, 0.5.6) win32-file-stat (1.3.3, 1.3.2) win32-process (0.6.0, 0.5.9) win32-sapi (0.1.4) win32-service (0.6.1) win32-sound (0.4.1) windows-api (0.3.0, 0.2.4) windows-pr (1.0.5, 1.0.2, 0.9.9, 0.9.8, 0.9.7, 0.9.6, 0.9.5, 0.9.4)

I'm on Windows Vista.

Any clue as how to solve this?

Thanks so much!

Wow, you have thousands of versions of the same libraries, why don't you start by deleting them?

gem clean

Should do it. Maybe you're getting a conflict of old gems trying to access new rails code.

Thanks for the suggestion, but I was anxious cleaning all of them as I use some old projects. But to get rid of all the fuzz I cleaned them. So no I have:

But the error still remains.

Solved it!!

I just bluntly uninstalled lots of gems including the Rails installations. And reinstalled the primary ones. Now it starts!

Thanks for your time!
