I have downloaded Lion and looking to install Ruby on Rails I have been scanning the web for a way to do this but can't seem to find a easy way, could anyone point me in the correct direction.

Help Much Appreciated

Thanks

Answer 1

Below I try to resume my rails installation. It should work well.

1) Download Xcode from Apple Application Store :

use this link : xcode

2) Install xcode :

Use finder=>applications to locate "Xcode installation icon and double-click on it to begin the installation

**2b.) For xcode 4.3. After installing xcode, launch it, navigate to Xcode->Preferences, Downloads tab. Install Command Line Tools. This will download and install C, compiler, loader and other command line utilities needed to compile & build the Ruby packages.

3) use a terminal to install git:

gem install git

and put this line in your .bash_profile (create one if none exists) :

export PATH=$PATH:/usr/local/git/bin/

4) use a terminal to install rvm:

bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )

and run this command to update your .bash_profile :

echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile

5) use a terminal to install ruby 1.9.2 and rails:

rvm autolibs enable 
rvm install 1.9.2
rvm --default 1.9.2
gem update
gem install rails

Answer 2

As of the latest version of lion (and having installed sass/compass/haml), if you type "rails" in the terminal and you dont have it, it will tell you to just do a sudo install right there. Hope its as easy for you as it was for me.
