where's rake?

I installed rubygems, and I got help output when I issued the command:

$ gem help

so I think ruby gems installed correctly. But when I tried to install
the Rake gem, this was the output:

$ gem install -r rake
Bulk updating Gem source index for: http://gems.rub...
ERROR: While executing gem ... (Gem::GemNotFoundException)
Could not find rake (> 0) in any repository

$ gem install -r rake
Bulk updating Gem source index for: http://gems.rub...
ERROR: While executing gem ... (Errno::EACCES)
Permission denied - /usr/lib/ruby/gems/1.8/cache/rake-0.7.3.gem

It looks like I'm supposed to change permissions on a directory. Here
are the permissions for cache:

drwxr-xr-x 3 root wheel 102 Oct 7 13:24 cache


Do I just need to give directory cache write access, or should I change
a permission on a higher directory as well?

Normally, unless you've custom installed gems to put things in your
own directory structure you run gem install as root.

In most modern systems this is best accomplished via

$sudo gem install rake

I assume that you do have root capabilities since you are talking
about changing permissions.

Thanks, that did the trick. :)

Is there any way to avoid this every time:

Bulk updating Gem source index for: http://gems.rub...

That hangs for 3-5 minutes.

It shouldn't any more. See [ruby-talk:272784].

Each user gets their own source_cache file, so you end up doing it
twice, once for yourself and once root. I think it would be ok to
copy root's source_cache, but that's not going to help much, since
its more likely to be out of date.

PS: What version is your RubyGems?

In 0.9.4 the maximum number of gems allowed to be out of date is a
tiny 50 before switching to a bulk update. In 0.9.5 the amount will
be boosted to 1000.
