Install PHP intl extension using Homebrew on XAMPP

Recently, when trying to install the PHP intl extension for a Symfony2 based web project using Homebrew to following error message kept showing up:

/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory /usr/local/bin/brew: line 23: /usr/local/Library/brew.rb: Undefined error: 0

This post steps explains what is needed to install PHP intl extension using Homebrew on XAMPP.

Reinstall required?

Trying to do a quick re-install did not succeed:

bash-3.2$ ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

It appears Homebrew is already installed. If your intent is to reinstall you should do the following before running this installer again:

bash-3.2$ rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup

So, basically it’s advised to remove existing files and re-start the installer which resulted in

rm: /usr/local/Cellar/libmemcached/1.0.18/AUTHORS: Permission denied
rm: /usr/local/Cellar/libmemcached/1.0.18/bin/memcapable: Permission denied
rm: /usr/local/Cellar/libmemcached/1.0.18/bin/memcat: Permission denied
… and many more errors

Sudo to the rescue?

Ok, so let’s remove the files using sudo:

bash-3.2$ sudo rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
Password: *****
/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/brew: line 23: /usr/local/Library/brew.rb: Undefined error: 0

Well, this is kind of embarrassing 🙂

Since the folder have been successfully removed it might just be the brew cleanup command that causes the problems?

bash-3.2$ sudo brew cleanup
/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/brew: line 23: /usr/local/Library/brew.rb: Undefined error: 0

It’s not 🙂 So, after manually removing these directories again it’s time for another attempt to call the brew installer:

bash-3.2$ ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”

Almost! As you can see we also need to manually remove the Library/Homebrew folder and finally it works:

bash-3.2$ ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”
