Missing require statement -- Yard won't run on 1.8.6 or 7 #178

walterdavis · 2010-09-28T02:30:54Z

Here's what I needed to do to make it work:

--- gems.rb (saved version)
+++ (current document)
@@ -44,6 +44,7 @@
end

   def add_gems(gems)

   require "enumerator"
 gems.each_slice(2) do |gem, ver_require|
   specs = Gem.source_index.find_name(gem, ver_require || ">= 0")
   @gems += specs unless specs.empty?

The text was updated successfully, but these errors were encountered:

Can you

a) show a backtrace
b) list your ruby version and environment (OS, anything important)
c) format a proper patch or submit a pull request

Thanks

Sorry, sure.
I started out on Ruby 1.8.6, no idea what patch level. I installed yard 0.6.1, and first tried to run yard server --gems, and found nothing would ever display. It would just spin and spin in the browser and never get anywhere. So I dug around in the documentation for a while and found the sudo yard gems command, and tried that, and got this error:

marvin:ci waltd$ sudo yard gems
Password:
/Library/Ruby/Gems/1.8/gems/yard-0.6.1/lib/yard/cli/gems.rb:47:in add_gems': undefined methodeach_slice' for []:Array (NoMethodError)
from /Library/Ruby/Gems/1.8/gems/yard-0.6.1/lib/yard/cli/gems.rb:70:in optparse' from /Library/Ruby/Gems/1.8/gems/yard-0.6.1/lib/yard/cli/gems.rb:18:inrun'
from /Library/Ruby/Gems/1.8/gems/yard-0.6.1/lib/yard/cli/command.rb:13:in run' from /Library/Ruby/Gems/1.8/gems/yard-0.6.1/lib/yard/cli/command_parser.rb:66:inrun'

from /usr/bin/yard:19

So I figured, my Ruby must be too old to know each_slice, I've been meaning to upgrade, so I installed 1.8.7 -p302 and tried again:

marvin:ruby-1.8.7-p302 waltd$ sudo yard gems
Password:
/Library/Ruby/Gems/1.8/gems/yard-0.6.1/lib/yard/cli/gems.rb:47:in add_gems': undefined methodeach_slice' for []:Array (NoMethodError)

from /usr/bin/yard:19

Same error. A quick google turned up the solution to include enumerable, which I did directly in my gems directory, without doing any of the things that would have made a proper diff or fork and pull request possible, and yard works fine now. I'll go through the steps, and send you a pull request. It does seem odd that you hadn't encountered this already from someone else.

The second error is the same as the first (you're still running 1.8.6 there). You have to make sure your 1.8.7 install is before your OSX ruby in your path. It is a 1.8.6 error, since each_slice isn't in 1.8.6. I'd suggest upgrading, but this will get fixed, thanks.

walterdavis · 2010-09-28T03:21:58Z

I beg to differ:

arvin:ruby-1.8.7-p302 waltd$ which ruby
/usr/local/bin/ruby
marvin:ruby-1.8.7-p302 waltd$ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin9.8.0]
marvin:ruby-1.8.7-p302 waltd$

That's the version that threw the second error, which stunningly looked just like the first one. I'm confused too. I'd restart my Mac, but I have too many other things open right now to do that.

Thanks very much for looking at this.

Except that when gem installs executables it hooks them up to a specific ruby install. The path /Library/Ruby/Gems/1.8/gems/yard-0.6.1 is definitely your OSX ruby, and nothing else. 1.8.7 should have its own gem path. You can test this with gem which yard.

walterdavis · 2010-09-28T03:25:46Z

Here's a little docu on the requirement: http://apidock.com/ruby/Enumerable/each_slice

lsegal · 2010-09-28T03:27:16Z

Thanks, but that only works on 1.8.7-- 1.8.6 does not have Enumerable classes, and 1.9.1+ does not have "enumerable" (it's builtin).

walterdavis · 2010-09-28T03:27:28Z

I uninstalled yard and re-installed it after I updated ruby, because I couldn't believe the error was exactly the same. And I updated gem in the process, too.

walterdavis · 2010-09-28T03:28:58Z

lsegal · 2010-09-28T03:31:11Z

What does gem env get you?

walterdavis · 2010-09-28T03:33:16Z

Here's the uninstall/reinstall (I just did it again)

marvin:ruby-1.8.7-p302 waltd$ sudo gem uninstall yard

The internal error was:

And now that I have the unpatched version once more, let's see what happens if I run the yard gems again:

marvin:ruby-1.8.7-p302 waltd$ sudo yard gems

once more, into the breach...

walterdavis · 2010-09-28T03:34:19Z

Well I'll be. Gem says it's using 1.8.6. WTF?

walterdavis · 2010-09-28T03:41:33Z

I have tried three times now to re-install gem with the new ruby, being as explicit as I know how to be with the installer, and each time gem env says the same thing. I wonder what could be going on here?

walterdavis · 2010-09-28T03:59:03Z

Restarting woke gem up to the new world order.

lsegal · 2010-10-03T06:46:27Z

Replace #each_slice with 1.8.6 compatible iteration.
