Generating RDoc fails with Directory .ext/rdoc already exists

Question

I'm just installing Ruby Enterprise and cannot change the output directory for this crashing command called by Ruby Enterprise installer.

So how do I delete the directory to satisfy this exception:

Generating RDoc documentation ./miniruby -I./lib -I.ext/common -I./- -r./ext/purelib.rb ./runruby.rb --extout=.ext -- "./bin/rdoc" --all --ri --op ".ext/rdoc" "."

Directory .ext/rdoc already exists, but it looks like it isn't an RDoc directory. Because RDoc doesn't want to risk destroying any of your existing files, you'll need to specify a different output directory name (using the --op option).

Had the same issue, if you can live without the developer docs then this workaround might help: http://groups.google.com/group/emm-ruby/browse_thread/thread/84f727edc32ac20e?pli=1

Running the installer like this sudo ./installer --auto=/usr/local/ruby-enterprise --no-dev-docs

Answer 2

You can most likely remove /opt/ruby-enterprise-edition-#{your_version}/.ext/rdoc and try again.

(Just guessing - I got this by reading ruby-enterprise-edition-1.8.7-2011.03.tar.gz: installer.rb line 215, and source/configure line 10872.)
