ruby-1.8.7-head: chomp called for nil:NilClass
-head ... sucks???

I am using ruby-1.8.7-head
with helps of RVM . This is the first time I've used a head
version of ruby
. And the first try is often hard :P
$ ruby -e "require 'rubygems'; require 'net/ssh'" /home/pi/.rvm/rubies/ruby-1.8.7-head/lib/ruby/1.8/logger.rb:174: private method `chomp' called for nil:NilClass (NoMethodError) from /home/pi/.rvm/rubies/ruby-1.8.7-head/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `gem_original_require' from /home/pi/.rvm/rubies/ruby-1.8.7-head/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:36:in `require' from /home/pi/.rvm/gems/ruby-1.8.7-head/gems/net-ssh-2.1.4/lib/net/ssh.rb:5 from /home/pi/.rvm/rubies/ruby-1.8.7-head/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:58:in `gem_original_require' from /home/pi/.rvm/rubies/ruby-1.8.7-head/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:58:in `require' from -e:1
There problem comes from logger.rb
. Let's take a look at the 174th line of the file:
1 class Logger
2 VERSION = "1.2.6"
3 id, name, rev = %w$Id$
4 ProgName = "#{name.chomp(",v")}/#{rev}"
In the official version (logger.rb from ruby-1.8.7
stable version):
1 class Logger
2 VERSION = "1.2.6"
3 id, name, rev = %w$Id: logger.rb 22285 2009-02-13 10:19:04Z shyouhei $
4 ProgName = "#{name.chomp(",v")}/#{rev}"
So the author used SVN ID string
to set some properties of the class. In HEAD version, such information wasn't substituted, as RVM
forked the source from a git repository
, not a subversion repository
. As git simply ignores $Id$
, it makes the head version stupid :))
As a work-around, I've just forced a phantom value for id,name,rev
:)
