Can't install gems with sudo

Ruby
1

I just built ruby 1.8.5 myself, and now rubygems can’t find remote gems
when I run it with sudo privs. It can find the gems when I run it as
myself, but then it doesn’t have priviliges needed to install the gem.
Did I miss something obvious?

[Sliver:~] gkistner$ which ruby
/usr/local/bin/ruby
[Sliver:~] gkistner$ which gem
/usr/local/bin/gem
[Sliver:~] gkistner$ ruby -v

OK, I get:

which ruby
/usr/local/bin/ruby
~ $ which gem
/usr/local/bin/gem
~ $ ruby -v
ruby 1.8.5 (2006-09-10) [powerpc-darwin8.7.0]
~ $ gem -v
0.9.0
~ $ sudo gem install rake

You didn’t miss anything obvious. I’m afraid that your problem is
subtle.

Looks like sudo might be giving you a dodgy path. Try this:

$ echo $PATH
$ sudo echo $PATH

Are they different?

Nope, identical path values.

Your source cache may be corrupt.

Try:
rm /usr/local/lib/ruby/gems/1.8/source_cache

Bingo, that was it! Thanks so much.
(Needed to “sudo rm …” that file, of course - I include the
information here only for posterity.)

Your source cache may be corrupt.

Try:

rm /usr/local/lib/ruby/gems/1.8/source_cache

(You also have one in ~/.gem/source_cache)
