Homebrew, Ruby, and Rails on OS X 10.10

OS X 10.10 Guide

Here's what I did to get things working.

1. Install Xcode 6

Yep, over at: https://developer.apple.com

2. Install the Command Line Tools (CLT)

http://adcdownload.apple.com/Developer_Tools/command_line_tools_os_x_10.10_for_xcode__june_2014/command_line_tools_for_osx_10_10_june_2014.dmg (thanks @thomaslindstrom)

3. Install Homebrew

Copy/pasted from the site:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

4. Update the brew Script

Open up /usr/local/bin/brew with your favorite editor.

I had to comment out the brew system detection, so that the last 6-7 lines looked like this:

#BREW_SYSTEM=$(uname -s | tr "[:upper:]" "[:lower:]")
#if [ "$BREW_SYSTEM" = "darwin" ]
#then
#    exec "$BREW_LIBRARY_DIRECTORY/brew.rb" "$@"
#else
    exec ruby -W0 "$BREW_LIBRARY_DIRECTORY/brew.rb" "$@"
#fi

5. Point Ruby 1.8 at Ruby 2.0

It looks like Homebrew somehow depends on Ruby being in Versions/1.8 (though even Mavericks ships with 2.0). Until Homebrew addresses this, we'll symlink our system version of Ruby to the one Homebrew looks for.

Create the folder:

sudo mkdir -p /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin

Then symlink the binary:

sudo ln -s /usr/bin/ruby /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

6. Hack away!

My subsequent brew install commands seemed to work fine (ruby-build, redis, etc...). Along with rbenv, etc.

You'll probably need to install Bundler with gem install bundler if you haven't already.

Improve this Gist!

Leave a comment if something didn't work.

I keep getting this error: /usr/local/Cellar/rbenv/0.4.0/libexec/rbenv-hooks: line 32: cd: ../../../Cellar/rbenv-gem-rehash/1.0.0/etc/rbenv.d/exec: No such file or directory whenever I try to run something like ruby -v. It only occurs when I have if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi in my .bash_profile. I installed with the instructions above and cannot figure this out! Any help is appreciated. Edit: I fixed this issue by doing brew install rbenv-gem-rehash.

The OpenSSL stuff didn't work for me, but just using CONFIGURE_OPTS="--with-gcc=clang" rbenv install 2.1.1 worked fine. Thanks for the tip.

The OpenSSL configure options in @jimbocortes' comment were f***ed up by the markdown parser, I believe. This worked for me:

CONFIGURE_OPTS="--with-openssl-dir=`brew --prefix openssl` --with-gcc=clang" rbenv install 2.1.2

Whoops, the Homebrew installer has moved! Please instead run:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Also, please ask wherever you got this link from to update it to the above.
Thanks!

I just installed this and it told me to get you to update the curl command for installing homebrew.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
