rspec users - Aug 2009 - "undefined method `gem' for main:Object" when installing rspec from the sources

Hello rspec,

I''m working on a Solaris rspec package (for OpenCSW). I pulled the
current git sources as described at http://wiki.github.com/dchelimsky/rspec
in the "Build and install the rspec gem from source" section. After
''rake gem'' I''m getting:

/export/home/maciej/src/rspec/Rakefile:92: warning: ambiguous first
argument; put parentheses or even spaces
rake aborted!
undefined method `gem'' for main:Object
/export/home/maciej/src/rspec/Rakefile:2
(See full trace by running task with --trace)
(in /export/home/maciej/src/rspec)

Does it mean that the gem target is missing from the Rakefile, or am I
doing something wrong?

More information:

$ rake --version
rake, version 0.8.7

That is a very old version of rubygems (2007-02-05) which probably
doesn''t support the gem method yet (just guessing). I''m using
1.3.4
(though it looks like there is a 1.3.5 version I missed). I''d
recommend upgrading.

Cheers,
David

I''ve upgraded rubygems:

maciej at solaris /export/home/maciej/src/rspec $ rake --version
rake, version 0.8.7
maciej at solaris /export/home/maciej/src/rspec $ gem --version
1.3.5

/export/home/maciej/src/rspec/Rakefile:2
(See full trace by running task with --trace)

I''ve re-run it with --trace:

Any ideas?

Ugy - sorry to put you through that to land in the same spot.

I really don''t have any ideas. I did run into an unrelated problem
(manifest was out of date) and just pushed the fix for that. I''m able
to build the gem using Ruby 1.8.7 with no warnings or errors.

Anybody else here familiar w/ Solaris/Ruby idiosyncrasies?

I checked it under Ubuntu Hardy:

$ rake --version
rake, version 0.8.1
$ gem --version
1.1.1

$ git clone git://github.com/dchelimsky/rspec.git
$ cd rspec
$ rake gem
(in /home/maciej/src/rspec)
rake aborted!
undefined method `gem'' for main:Object
/home/maciej/src/rspec/Rakefile:2
(See full trace by running task with --trace)

The same symptoms... it could due to gem version 1.1.1, though. Okay,
testing with a newer version, on a different Linux box:

maciej at fennel ~/src $ git clone git://github.com/dchelimsky/rspec.git

(See full trace by running task with --trace)
maciej at fennel ~/src/rspec $ rake --version
rake, version 0.8.7
maciej at fennel ~/src/rspec $ gem --version
1.3.1

So, the same symptoms, tested on Ubuntu Hardy, Gentoo and Solaris 10.
It''s weird that you can''t reproduce the issue. Perhaps try
with a
fresh system? I install: ruby, rubygems, rake, git. Then the above
sequence.

Not really the same symptoms. "Could not find RubyGem hoe" is not the
same issue as "undefined method `gem''" The gem problem is
related to
outdated versions of rubygems. The hoe problem is solved with "gem
install hoe"

To clarify - try, on the last linux box you described:

$ gem install hoe
$ rake gem

You may need other gems at this point, but if you do you''ll get error
messages like "Could not find RubyGem foo," in which case you would
then say:

$ gem install foo

You''re very close. Let us know when you get it working.
