The Problem

If you have installed the standalone Command Line Tools for XCode on your Mac (i.e. without having XCode.app installed), some of these tools can get a bit confused due to a couple of oversights on Apple's part in finalising the setup.

Note: all commands below will need to be run from an Administrator account, or by an account with appropriate permission in /etc/sudoers.

The Solution

1. Failing to Find Frameworks

Sometime when compiling against the preinstalled Frameworks (e.g. Ruby or Python), various tools will inexplicable fail to find header files that are quite clearly there. This is caused by the fact that no XCode has been selected for the command-line tools. Wait, I hear you cry, I don't have XCode installed! Indeed, but you nonetheless need to select one, and point it somewhere where the command line tools exist, like so

30 秒認識 vagrant:

Vagrant 是一個 ruby 寫的工具，它是一個 DSL 讓開發者可以輕易控制 VirtualBox 的 VM 。用它可以輕鬆管理和制作我們理想中的開發環境。

  $ gem install vagrant #安裝 vagrant
  $ vagrant box add ubuntu http://cloud-images.ubuntu.com/vagrant/quantal/current/quantal-server-cloudimg-i386-vagrant-disk1.box #安裝新的 Vagrant Package。這裡的 ubuntu 是一個預先做好的空的 ubuntu 12.10 (intel-based) 
  $ vagrant init ubuntu  
  $ vagrant up

此時就可以使用 vangrant ssh 連到vm了，預設使用者/密碼為 vangrant/vangrant

	# sudo ln -s ~/nginx.conf unicorn.conf
	upstream app_server {
	server unix:/tmp/unicorn_padrino.sock fail_timeout=0;
	}

	server {
	listen 80;
	charset utf-8;
	server_name db.innshine.com;

	app_root = "/root/path/of/app"
	app_name = "demoapp"
	listen "/tmp/app.sock", :backlog => 2048 #這邊要跟nginx虛擬主機檔中upstream內定義的務必一樣
	worker_processes 4 #看情況開
	preload_app false
	timeout 30

	module Rails
	class <<self
	def root

	rbenv install 1.9.3-p194
	rbenv rehash # for paranoia's sake
	rbenv global 1.9.3-p194
	gem env # to check that everything was pointing at 1.9 and not the system
	gem install --no-ri --no-rdoc bundler
	rbenv rehash # necessary to load up the bundle executable
	bundle --path=vendor/bundle

	select carts.`order_number`, products.`shipping_itemsize`, count(products.`shipping_itemsize`)
	from carts inner join products on carts.`product_id` = products.`id`
	group by carts.order_number, products.`shipping_itemsize`;

	carts = Arel::Table.new(:carts)
	products = Arel::Table.new(:products)
	orders = Arel::Table.new(:orders)

	subquery = carts.join(products).project("carts.order_number, products.shipping_itemsize as size, count(products.shipping_itemsize) as size_count").group("carts.order_number, products.shipping_itemsize")
