I’m getting the message

ERROR: While executing gem … (ArgumentError)  
string contains null byte

My RAILS implementation is now completely out of sync. All other gems  
are updated to latest except ActiveSupport. rake rails:update:configs  
is aborting because ActiveSupport is wrong version.

Any help would be appreciated!

Now I’m totally hosed. I tried to reinstate an older version of  
RAILS, and I can’t start my server. The error I’m getting is:

Exiting

Fixed.

Don’t know what happened but reinstalling ruby gems did the trick.  
Running now on rails 1.2.4. Still have question about download  
failure of Rails 1.2.6 gem.
