I wrote a gem for a package called “tree”, version 0.0.0. I built a
gemfile and installed it. Now the code is installed and works, but
only some of the gem utitlities know that it’s there. I suspect I did
something wrong in my gem specification file, but I can’t figure out
what.
Does anyone have any ideas what is wrong or suggestions on how to
debug?
Here are the specifics of the problem: “gem list” and “gemwhich” find
my gem
$ gem list
*** LOCAL GEMS ***
rake (0.6.2)
Ruby based make-like utility.
rubygems-update (0.8.11)
RubyGems Update GEM
sources (0.0.1)
This package provides download sources for remote gem installation
tree (0.0.0)
Tree is an ordered n-ary branching tree structure
$ gemwhich tree
/homes/billmcn/lib/ruby/gems/1.8/gems/tree-0.0.0/lib/tree.rb
but ‘gem specification’ and ‘gem uninstall’ do not work
$ gem specification tree
ERROR: Unknown gem tree
$ gem uninstall tree
Attempting to uninstall gem ‘tree’
ERROR: While executing gem … (RuntimeError)
Unknown RubyGem: tree (> 0)
These commands work for other gems installed on my machine.
When I go look under /homes/billmcn/lib/ruby/gems/1.8 there appear to
be the appropriate cache, doc, gems, and specifications files and
subdirectories. In particular, here is the specfile
$ cat tree-0.0.0.gemspec
Gem::Specification.new do |s|
s.name = %q{tree}
s.version = “0.0.0”
s.date = %q{2005-12-01}
s.summary = %q{Tree is an ordered n-ary branching tree structure}
s.email = %q{[email protected]}
s.homepage = %q{http://www.washington.edu/~billmcn}
s.description = %q{This module implement order n-ary branching tree
structures. It includes support for breadth- and depth- first
iteration, and serialization to and from a bracketed tree string.}
s.has_rdoc = true
s.authors = [“W.P. McNeill”]
s.files = [“test/test_tree.rb”, “lib/tree.rb”, “README”]
s.test_files = [“test/test_tree.rb”]
s.rdoc_options = [“–title”, “Tree – Ruby Tree”, “–main”, “README”,
“–line-numbers”, “–inline-source”]
s.extra_rdoc_files = [“README”]
end
This is RedHat Linux. Ruby version
$ ruby -v
ruby 1.8.3 (2005-09-21) [i686-linux]
Note that I don’t have write permissions to /usr so this version of
Ruby is installed in my home directory.
RUBYOPT=rubygems is set. Here is my gems environment
$ gem env
