Re: [Geeknight-Dallas] Installing languages for Seven in Seven on OS X

If you don't have ruby installed, or if you see yourself doing any future development with Ruby, or want to play around with the latest version, I highly recommend considering rvm (Ruby Version Manager) to install Ruby. It's really easy to use and manage. To install: http://beginrescueend.com/rvm/install/. (Note: don't try installing rvm with homebrew, use the bash script provided). Basic usage: http://beginrescueend.com/rvm/basics/

I can help people get set up on Wednesday if they need help.

It's a great tool that allows you to have multiple rubies (ruby versions, 1.8.7, 1.9.2, etc) and gemsets installed on your your system. Here's an example series of commands with RVM installed, assuming you already have RVM and a native ruby version (in this case 1.8.7):

$ ruby -v
1.8.7
$ rvm install 1.9.2
[Installs 1.9.2]
$ rvm use 1.9.2
$ ruby -v
1.9.2
$ rvm use system 
[switches to use native ruby that ships with your system, not managed with RVM]
$ ruby -v
1.8.7
$ which ruby
[path/to/system/ruby/1.8.7/installation]
$ rvm install 1.8.7
[Installs 1.8.7, but this version will be managed with RVM]
$ rvm use 1.8.7
[switches to use ruby 1.8.7 managed by rvm]
$ ruby -v
1.8.7 
$ which ruby
[path/to/rvm/ruby/1.8.7/installation]

FWIW, when I was using snow leopard, I managed to install ruby both from source and using mac ports.

Hi All,

Not sure if you all will have the same issue I had with Io install on OSX, but...for me -

1.  The brew install did not work on Snow Lep


3.  Still had this issue and had to change a C header file - https://github.com/stevedekorte/io/issues/135#issuecomment[masked]
see orchistro post for a good summary / diff of the changes to make.

I already had ruby 1.8.7 installed.

There are homebrew recipes for all the other languages:

  • brew install io
  • brew install gnu-prolog
  • brew install scala
  • brew install erlang
  • brew install clojure clojure-contrib
  • brew install haskell-platform
