Best way start fresh install OSX

Ruby
1

I’ve installed multiple versions in multiple places trying to get
everything up and working, what’s the best way to start fresh? Below
are some of the errors with brew and the different ways I’ve tried to
install Ruby and getting it working properly.

=== brew errors ===

mbp:~ teedubb$ brew update
/usr/local/bin/brew: /usr/local/Library/brew.rb:

interpreter: No such file or directory
/usr/local/bin/brew: line 21: /usr/local/Library/brew.rb: Undefined

The shebang is wrong. Do:

ruby -S brew update

And it’ll prolly even fix the shebangs.

What Ryan suggested:

ruby -S brew update

What you say you did:

mbp:~ teedubb$ brew -s brew update

And it “didn’t work”. Huh. Fancy that.

That didn’t work for me.

mbp:~ teedubb$ brew -s brew update
/usr/local/bin/brew: /usr/local/Library/brew.rb:
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad

Now I’m getting a different error

mbp:~ brew$ ruby -S brew update
ruby: no Ruby script found in input (LoadError)

ruby: no Ruby script found in input (LoadError)

But ruby works aside from that?

It’s a good idea, but unfortunately not going to work, homebrew is
bootstrapped with a shellscript, not Ruby:

cat “$(which brew)” && echo ---------
#!/bin/sh
BREW_FILE_DIRECTORY=$(dirname “$0”)
BREW_FILE_DIRECTORY=$(cd “$BREW_FILE_DIRECTORY” && pwd -P)

BREW_FILENAME=$(basename “$0”)
export HOMEBREW_BREW_FILE=“$BREW_FILE_DIRECTORY/$BREW_FILENAME”

BREW_SYMLINK=$(readlink $0)
if [ -n “$BREW_SYMLINK” ]
then
BREW_SYMLINK_DIRECTORY=$(dirname “$BREW_SYMLINK”)
BREW_FILE_DIRECTORY=$(cd “$BREW_FILE_DIRECTORY” &&
cd “$BREW_SYMLINK_DIRECTORY” && pwd -P)
fi

BREW_LIBRARY_DIRECTORY=$(cd “$BREW_FILE_DIRECTORY”/…/Library && pwd -P)

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

Notice the exec at the bottom. Lets check that out:

head -1 “$(which brew)/…/…/Library/brew.rb”
#!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby
-W0

So it’s shebang is hard-coded path to a Ruby it expects to be there. The
question is why yours isn’t there (IDK the answer) and how to get it
back.
IDK if there’s a way to get files back like that, but I’d probably try
either building Ruby 1.8 at that dir, or installing Ruby 1.8 and making
a
symlink or shell script or something. Brew may not be the only program
to
use this Ruby, you could have other things break b/c that Ruby isn’t
there.
