From: James Britt Date: 2004-11-04T08:51:06+09:00 Subject: [RAKE] rdoc task fails on Win2k When using rake to create rdoc files on Windows 2000, I get this error rdoc -o doc --main 'README.rdoc' -T 'html' README.rdoc ./lib/catapult.rb ./lib rake aborted! Command Failed: [rdoc -o doc --main 'README.rdoc' -T 'html' README.rdoc ./lib/catapult.rb ./lib] But if I copy and paste that top command string, it runs fine in a CMD box. Here's the task def: Rake::RDocTask.new( :rdoc ){ |rd| rd.rdoc_dir = 'doc' rd.rdoc_files.add( 'README.rdoc', './lib/catapult.rb', './lib' ) rd.main = "README.rdoc" } Specs: ruby 1.8.2 (2004-07-29) [i386-mswin32] rake, version 0.4.9 I saw a similar message posted here about this problem on WinXP, but did not see a reply. James P.S. I updated my Rake gem before writing, to see if the current version fixed this issue. I used this command: gem update rake which just seemed like The Way It Would Work. But it updated all my gems. Which, after running 'gem help update', I then understood. Is there a way to update just a particular gem file? In lieu of that, shouldn't I get an error for passing an unknown parameter, so at least I don't run something I didn't intend?
