Yet another site_ruby question

ruby-talk
1

Hello all,

Here's the LOAD_PATH for my desktop:
/usr/local/lib/ruby/site_ruby/1.8
/usr/local/lib/ruby/site_ruby/1.8/powerpc-darwin8.10.0
/usr/local/lib/ruby/site_ruby
/usr/local/lib/ruby/1.8
/usr/local/lib/ruby/1.8/powerpc-darwin8.10.0
.

Here's the LOAD_PATH for my laptop:
/usr/local/lib/ruby/site_ruby/1.8
/usr/local/lib/ruby/site_ruby/1.8/i686-darwin8.9.1
/usr/local/lib/ruby/site_ruby
/usr/local/lib/ruby/1.8
/usr/local/lib/ruby/1.8/i686-darwin8.9.1
.

Installed gem 'flacinfo-rb' and the path looks like this on both
machines:
/usr/local/lib/ruby/gems/1.8/gems/flacinfo-rb-0.3/flacinfo.rb
(although I would have expected to find it here:
/usr/local/lib/ruby/site_ruby/1.8/flacinfo.rb)

On my laptop success with:
irb(main):001:0> require 'flacinfo'
=> true

On my desktop this:
irb(main):001:0> require 'flacinfo'
LoadError: no such file to load -- flacinfo
        from (irb):1:in `require'
        from (irb):1

If I move the gem to site_ruby on my desktop, the load succeeds. My
question is why the inconsistency?
If the install location is incorrect why does require work on one
machine and not the other?

Here's the result of the install command on both machines:
Successfully installed flacinfo-rb-0.3
Installing ri documentation for flacinfo-rb-0.3...
File not found: lib

Is that last bit significant?

Thanks for any info,
Dan J.

Hi Daniel,

Did you tried by using "gem" command ?
(gem instead of require_gem, which is obsolete)
Maybe in one machine, by default, that lib is loaded and on the other
one, not?
I'm just guessing.

All the best,

Alin

You need to require 'rubygems' first. This probably isn't required
because you have RUBYOPT set on your desktop, but not your laptop

Thanks Alin,

Here's the result of my experiment with the gem command:

$ irb
irb(main):001:0> gem 'flacinfo'
NoMethodError: undefined method `gem' for main:Object
        from (irb):1
irb(main):002:0> require 'rubygems'
=> true
irb(main):003:0> gem 'flacinfo'

        from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:238:in

=> true
irb(main):005:0> song = FlacInfo.new("dread.flac")
NameError: uninitialized constant FlacInfo
        from (irb):5

'require' and 'gem' really want to find the library under 'site_ruby.'
If I move it there, everything works. I just still can't figure out why
it works without being in 'site_ruby.' on my other machine. :frowning: The
installations of ruby, rubygems, etc. where exactly the same on both.

You need to require 'rubygems' first. This probably isn't required
because you have RUBYOPT set on your desktop, but not your laptop

Thanks Chris,
I did try that...

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'flacinfo'
LoadError: no such file to load -- flacinfo
        from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require'
        from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`require'
        from (irb):2

This isn't necessarily a show stopper, because of course I can just
move the library, but I'm trying to understand the process.

Hi Daniel,

As the author of flacinfo, and as one who is not overly familiar with the
inner workings of gems, would not overlook that this may be a problem with
the gem itself. It does seem to work fine on the (Linux) system that I tested
it on.

Does your problem occur with all gems or just flacinfo?

How about:
require 'rubygems'
require 'flacinfo-rb'

?

Yeah, I tried that too. The load succeeds but then the methods fail:
Should work like this:

irb(main):001:0> require 'flacinfo'
=> true
irb(main):002:0> song = FlacInfo.new("dread.flac")
=> #<FlacInfo:0x19208 (STREAMINFO size=34 offset=8) (SEEKTABLE size=486
offset=46) (VORBIS_COMMENT size=235 offset=536) (PADDING size=4065
offset=775)>
irb(main):003:0> song.print_tags
ARTIST: 10cc
TRACKNUMBER: 01
DATE: 1978
vendor_tag: reference libFLAC 1.1.2 20050205

TITLE: Dreadlock Holiday
YEAR: 1978
GENRE: Rock
offset: 536
block_size: 235
COMMENT: High Quality, EAC secure, Lossless flac
=> nil

But instead I get:

irb(main):001:0> require 'rubygems'

irb(main):002:0> gem 'flacinfo-rb'
=> true
irb(main):003:0> song = FlacInfo.new("dread.flac")

inner workings of gems, would not overlook that this may be a problem with
the gem itself. It does seem to work fine on the (Linux) system that I tested

Hi Darren,
It did actually occur to me along the way that I should ask you about
this. :wink:

I haven't had this problem with other gems that I know of. One thing I
wonder about is whether the gem is correctly placed during the install,
because I believe that 3rd-party gems are supposed to go under
site_ruby. (On my machine: /usr/local/lib/ruby/site_ruby/1.8)

Here's the install:

sudo gem install -r flacinfo-rb
Successfully installed flacinfo-rb-0.3
Installing ri documentation for flacinfo-rb-0.3...
File not found: lib

Which puts it here:
/usr/local/lib/ruby/gems/1.8/gems/flacinfo-rb-0.3

I can move flacinfo.rb to site_ruby/1.8 and everything works fine.

The odd thing is that on one machine (my Intel Mac), require 'flacinfo'
works without being moved, but on my desktop machine it doesn't.

And finally, the REAL problem is me making a mountain out of a molehill!

Regards,
Dan J.

require 'flacinfo' (or 'flacinfo-rb') after the gem line. 'gem' just
activates the gem, you still need to require it.

Yeah, I tried that too. The load succeeds but then the methods fail:
Should work like this:

irb(main):001:0> require 'flacinfo'
=> true
irb(main):002:0> song = FlacInfo.new("dread.flac")
=> #<FlacInfo:0x19208 (STREAMINFO size=34 offset=8) (SEEKTABLE size=486
offset=46) (VORBIS_COMMENT size=235 offset=536) (PADDING size=4065
offset=775)>
irb(main):003:0> song.print_tags
ARTIST: 10cc
TRACKNUMBER: 01
DATE: 1978
vendor_tag: reference libFLAC 1.1.2 20050205
ALBUM: Bloody Tourists
TOTALTRACKS: 13
TITLE: Dreadlock Holiday
YEAR: 1978
GENRE: Rock
offset: 536
block_size: 235
COMMENT: High Quality, EAC secure, Lossless flac
=> nil

But instead I get:

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> gem 'flacinfo-rb'
=> true
irb(main):003:0> song = FlacInfo.new("dread.flac")
NameError: uninitialized constant FlacInfo

Hi Darren,
It did actually occur to me along the way that I should ask you about
this. :wink:

I haven't had this problem with other gems that I know of. One thing I
wonder about is whether the gem is correctly placed during the install,
because I believe that 3rd-party gems are supposed to go under
site_ruby. (On my machine: /usr/local/lib/ruby/site_ruby/1.8)

Here's the install:

sudo gem install -r flacinfo-rb
Successfully installed flacinfo-rb-0.3
Installing ri documentation for flacinfo-rb-0.3...
File not found: lib

Which puts it here:
/usr/local/lib/ruby/gems/1.8/gems/flacinfo-rb-0.3

I can move flacinfo.rb to site_ruby/1.8 and everything works fine.

The odd thing is that on one machine (my Intel Mac), require 'flacinfo'
works without being moved, but on my desktop machine it doesn't.

And finally, the REAL problem is me making a mountain out of a molehill!

Nope. It's a bug...

Regards,
Dan J.

After a bit of poking around I can say this is certainly a problem with the
gem itself. In the latest version (0.3) I have forgotten to place the source
file itself in a 'lib' subdirectory as recommended by the 'Creating your own
gems' example in the pickaxe book.

I am going to build a 0.3.1 gem release which will address this bug (but not
change any functionality of the library itself) and will try to get it up on
Rubyforge in the next hour or so.

Thanks for bringing this to my attention :wink:

require 'flacinfo' (or 'flacinfo-rb') after the gem line. 'gem' just
activates the gem, you still need to require it.

Alas, no joy.

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> gem 'flacinfo-rb'
=> true
irb(main):003:0> require 'flacinfo'
LoadError: no such file to load -- flacinfo
        from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`gem_original_require'
        from
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in
`require'

same result for require 'flacinfo-rb'

Weird. Last night I did a near clean install of ruby, et al. on both
machines to try and narrow down the possibilities. Didn't seem to make
a difference. My MacBook Pro doesn't care if flacinfo.rb is under
site_ruby but my destop does. ??

Thanks again for your help.

This is a long shot, but is there a significant difference between the
environment variables on each OSX installation?

They are identical.
