I made the mistake of trying to upgrade to 1.8.4 from 1.8.2 and had intended
to upgrade to rails 1.1. I have now completely borked my ruby gems
installation. After installing ruby I get the following error when trying to
execute gem:
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require__'': no such file to load -- zlib (LoadError)
from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require''
from /usr/local/lib/ruby/site_ruby/1.8/rubygems/package.rb:9

`require''
from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:61:in
`manage_gems''
from /usr/local/bin/gem:4
So I decided to re-install rubygems. When trying to run setup.rb I get:
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require__'': no such file to load -- zlib (LoadError)
from

The "/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require__'': no such file to load -- zlib (LoadError)" entry seems
to be
trying to "require__ path" at line 21 of custom_require.rb line 21.
Can anyone help me get my rails back? I swear I''ll never try to upgrade
again..:-)

Did you install > Ruby from source?---- Chad - your presence on the list usually signifies another update to Recipes...is that forthcoming RSN? I haven''t updated my pdf from the last update and I was kind of waiting for the next update because I am rapidly approaching the moment where I will have time and my understanding of rails has improved to the point that I might be able to better grok the things in your book.

not sure what OS you''re on but make sure you have installed the zlib-devel in addition to zlib package if it''s appropriate for you - i had this exact issue a while back may have to reinstall gems too, i can''t remember sorry On Friday 31 March 2006 21:57, Stuart Batty wrote:> I made the mistake of trying to upgrade to 1.8.4 from 1.8.2 and had > intended to upgrade to rails 1.1.

Chad,
Thank you for the information. Yes, I did install ruby from source (v1.8.4)
on Ubuntu 5.10. You are correct about zlib. I got the following message:
stuart@kubuntu:~$ irb
irb(main):001:0> require ''zlib''
LoadError: no such file to load -- zlib
from (irb):1:in `require''
from (irb):1
irb(main):002:0> exit
Zlib was installed at one time but it is now either among the absentees or
somehow munged beyond repair. I''ll reinstall zlib and see where that
gets
me.
I can''t believe I actually got help from Chad Fowler....how cool is
that?

Thanks Scott and Patrick as well. I re-installed zlib and zlib-devel and re-compiled ruby and I was able to setup rubygems. Thanks again. Patrick, can you explain a little more about the readline dev stuff? What packages do I need for Ubuntu? Should I install the readline dev stuff and then re-compile ruby again so it will "pick up" the readline dev libs? -- View this message in context: http://www.nabble.com/Install-rubygems-error-t1376938.html#a3700935 Sent from the RubyOnRails Users forum at Nabble.com.
