Looks like there may be a problem with Rake 0.6.2 and Ruby 1.8.4. If  
I have a task that uses either chdir or cd, I get an error:

rake aborted!  
no such option: noop  
/Users/jamis/ruby184/lib/ruby/1.8/fileutils.rb:1422:in  
`fu_check_options' /Users/jamis/ruby184/lib/ruby/1.8/fileutils.rb:119:in`cd’  
/Users/jamis/ruby184/lib/ruby/gems/1.8/gems/rake-0.6.2/lib/rake.rb:  
640:in `cd’  
./rakefile:67

Apparenly, FileUtils.chdir doesn’t take the :noop parameter anymore?  
I’m working around this by just invoking FileUtils.chdir directly.

There’s this in the change log:

I think you are supposed to use FileUtils::DryRun somehow instead.  
Haven’t looked at it in detail…

IIRC I encountered this very bug some time ago, with 1.8.3. The advice I  
found at the time was to switch to a beta version, 0.6.99.2, which you  
can  
find at: [http://onestepback.org/betagems/gems/rake-0.6.99.2.gem](http://onestepback.org/betagems/gems/rake-0.6.99.2.gem) . Since  
making the switch I’ve encountered no such problems; I’ve just tried the  
following Rakefile with 1.8.4:

```
task :default do
  chdir('..') do
    puts `pwd`
  end
end

```

And it gives:

```
(in /home/rosco/dev/ruby/raketest)
cd ..
/home/rosco/dev/ruby
cd -

```

Rake 0.6.99.2 is the release candidate for Rake 0.7.0. There is still  
some documentation to be done, but I plan to finish that this week and  
officially release a new version of rake.
