Gem trouble

[Benjohn Barnes]

I've been trying to use gems to instal rucola, and things aren't
going too well.

I'm using os x 10.4, and Ruby 1.8.2 on a power PC machine. My gem
version is 0.9.5

I was getting this segmentation fault:

/usr/lib/ruby/site_ruby/1.8/rubygems/package.rb:620: [BUG]
Segmentation fault
ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]

I checked the line mentioned, and found this:

# NOTE: Originally this method used two approaches, Return a
GZipReader
# directly, or read the GZipReader into a string and return a
StringIO on
# the string. The string IO approach was used for versions of
ZLib before
# 1.2.1 to avoid buffer errors on windows machines. Then we
found that
# errors happened with 1.2.1 as well, so we changed the
condition. Then
# we discovered errors occurred with versions as late as
1.2.3. At this
# point (after some benchmarking to show we weren't seriously
crippling
# the unpacking speed) we threw our hands in the air and
declared that
# this method would use the String IO approach on all platforms
at all
# times. And that's the way it is.
def zipped_stream(entry)
# This is Jamis Buck's ZLib workaround. The original code is
# commented out while we evaluate this patch.
entry.read(10) # skip the gzip header
zis = Zlib::Inflate.new(-Zlib::MAX_WBITS)
is = StringIO.new(zis.inflate(entry.read))
# zis = Zlib::GzipReader.new entry
# dis = zis.read
# is = StringIO.new(dis)
ensure
zis.finish if zis
end

So I swapped out the patch and reverted to the earlier version. This
seems to have worked around the SEG fault, but now I'm getting this
instead:

ERROR: While executing gem ... (TypeError)
cannot convert nil into Array

This is all the errors / diagnostic information I get with the -V
(verbose) option.

Can anyone adviseon getting everything working smoothly again? My
apologies if I have left out critical and obvious diagnostic
material. I've just done a disk verify, and that's also come up clean
(not sure how thorough the Mac "Disk Utility" is).

Thanks very much,
Benjohn

One useful thing - this seems to happen for other gems too:

benjohn # sudo gem instal sqlite
Password:
Updating metadata for 9 gems from http://gems.rubyforge.org

or

benjohn # sudo gem instal nitro -V

ERROR: While executing gem ... (TypeError)

Thanks,

Try:

gem --debug install ...

Try:

gem --debug install ...

Thanks Eric!

I was going to try this when I got back from work, but work can wait
a few more minutes, I'm sure

Here's what it says:

So, some worrying looking stuff at the start that it gets past, and
then perhaps no gem matches the version requirements that it's got at
a later point? I'll dig deeper tonight if no one recognises this one
and comes back with a suggestion.

Thanks again!

Cheers,
Benjohn
