rubygems - May I gem update --system?

cems · 2008-04-06 15:39:04

I did like it was told in newsletter for April 3, 2008. But now I have:

[root@silverhawk ~]# pacman -Qs rubygems
local/rubygems 1.0.1-1
A package management framework for the Ruby programming language
[root@silverhawk ~]# gem --version
1.1.0

Will it break something when upgrading rubygems from pacman? If so, how can I undo the manual upgrade?

Thank you

Workaround in http://bugs.archlinux.org/task/10117

Nice you found the workaround and shared it with us, thanks. I guess I have to do something about that, any suggestions?

What happened is quite natural, if you understand how does pacman work.
1. Pacman remembers which files were installed with which package.
2. If you 'gem --update system', the pacman's list of files belonging to rubygems package is no longer accurate, since files from old version have been removed and files from the new version have been introduced into the filesystem.
3. When the new rubygems pacman package comes out, of course it will contain files, which are already in the filesystem (by manual update), and so pacman will complain that some files that it's about to copy over are already there.

All in all, I think the workaround is unnecessarily complicated. You don't need to archive the conflicting files, just overwrite them (they are the same anyway) -> pacman -Sf rubygems.

EDIT: By the way, this happens every time you update something manually, without waiting for a pacman package to appear. If you *really* need to update, just use ABS, bump up the version number, and makepkg a new package.

@kensai: If you could squeeze a note about this to the news, it would be excellent; although I don't think there are too many people affected by this, so maybe this thread is enough.

Yeah, I'll add the link to this thread. Thanks.
