I could be doing something wrong, but this is how it went. 1. I try installing “rvm install macruby-head” (I have not yet installed llvm since i am not sure what version to use) 2. I get an error about not having LLVM. I go through source and find a README.rdoc file which gives me the correct LLVM version. ( svn co -r 106781 [https://llvm.org/svn/llvm-project/llvm/trunk](https://llvm.org/svn/llvm-project/llvm/trunk) llvm-trunk) _Now this could have been on the Macruby install page to make things easier_. I install LLVM. (It installs in /usr/local … i don’t have this in path since i use macports) 1. Now the README.rdoc wants me to do “rake” and “sudo rake install”. I do rake, but then remember that RVM does not want me to do sudo at all. 2. So I resume: rvm install macruby-head It prompts me for sudo password in order to do a “sudo rake install”. Here’s the error i get: /Users/rahul/.rvm/rubies/ruby-1.9.2-head/lib/ruby/1.9.1/rubygems.rb:340:in `bin_path': can't find executable rake for rake-0.8.7 (Gem::Exception) from /Users/rahul/.rvm/gems/ruby-1.9.2-head/bin/rake:19:in `’ (WHy is it complaining about **1.9.1** inside 1.9.2 ???) When i do “sudo rake install” myself, i get the same error. 1. So now I do just “rake install”. Seems to go well. installing rdoc installing binary commands installing command scripts installing library scripts installing headers installing manpages installing data files installing extension objects installing extension scripts installing Xcode 3.x templates installing Xcode templates installing samples installing framework /Users/rahul/.rvm/src/macruby-head/lib/fileutils.rb:1420:in `fu_each_src_dest0:': Permission denied - (../../../Library/Frameworks/MacRuby.framework/Versions/Current/usr/bin/macgem, /usr/local/bin/macgem) (Errno::EACCES) from /Users/rahul/.rvm/src/macruby-head/lib/fileutils.rb:342:in `symlink:’ from /Users/rahul/.rvm/src/macruby-head/instruby.rb:3:in `’ rake aborted! Command failed with status (1): [./miniruby instruby.rb –make="/usr/bin/ma…] Oops. It needs sudo access, but in sudo access it won’t have access to my RVM ruby!!! 1. So now i don’t have any executables. I use mdfind and find that these executable seem to be lying around: ls /Library/Frameworks/MacRuby.framework/Versions/0.7/usr/bin/ macgem\* macrake\* macri\* macruby\_deploy\* macrubyc\* rb\_nibtool\* macirb\* macrdoc\* macruby\* macruby\_select\* macrubyd\* So perhaps I need to just copy these into /usr/local/bin. Or somewhere into RVM. Could someone clarify what i should do now. Where did I go wrong ? Why is rvm install failing ? thanks. ---

Also, i tried copying the files from /Library/Frameworks/MacRuby.framework/Versions/0.7/usr/bin/ to /usr/local/bin and trying out “macirb”. It won’t load: 2010-08-20 20:43:06.702 macruby[75748:903] \*\*\* Terminating app due to uncaught exception ‘NoMethodError’, reason: ‘undefined method `split’ for nil:NilClass (NoMethodError) ’ \*\*\* Call stack at first throw: ( 0 CoreFoundation 0x00007fff80132cc4 \_\_exceptionPreprocess + 180 1 libobjc.A.dylib 0x00007fff82ea20f3 objc\_exception\_throw + 45 2 libmacruby.dylib 0x0000000100154445 rb\_vm\_raise + 437 3 libmacruby.dylib 0x000000010003fdf9 rb\_exc\_raise + 9 4 libmacruby.dylib 0x0000000100151db6 rb\_vm\_method\_missing + 566 5 libmacruby.dylib 0x0000000100141ab9 rb\_vm\_dispatch + 6841 6 libmacruby.dylib 0x0000000100144a54 rb\_vm\_yield\_args + 3044 7 libmacruby.dylib 0x00000001001406a8 rb\_vm\_dispatch + 1704 8 deprecated.rbo 0x0000000102df2413 MREP\_B11FADFC64CD4989998BA496E66B8860 + 2211 ) terminate called after throwing an instance of ‘NSException’ * * * I’ve tried to leave a message on [irc.freenode.net](http://irc.freenode.net) but am totally lost – never used IRC before. ---

Sorry if I > wasn’t clear. My copying the files to /usr/local/bin was actually a continuation of my first post wherein I mentioned that the files were created. In case anyone reading got the impression my problem was solved, i was just clarifying that the executables are not running. Cheers. ---

I was just trying to answer your question as to why files are installed into foo/lib/ruby/1.9.1 when you’re building ruby 1.9.2. When ruby is being built, it may be told to build somewhere other than /usr/local. In your case it looks like rvm is building it under /Users/rahul/.rvm/gems/ruby-1.9.2-head/. But the lib dir is still intentionally …/1.9.1/… > Also, i tried copying the files from > /Library/Frameworks/MacRuby.framework/Versions/0.7/usr/bin/ to > /usr/local/bin I didn’t mean that you should copy files anywhere else. Sorry if I wasn’t clear.
