[PHP 學習筆記] 套件管理系統 Composer

Composer 是 PHP 的套件管理系統，方便你安裝、刪除，管理你的套件（package）。

使用安裝（Globally (on OSX via homebrew)）：

  brew update
  brew tap homebrew/homebrew-php
  brew tap homebrew/dupes
  brew tap homebrew/versions
  brew install php55-intl
  brew install homebrew/php/composer

故障排除：
若使用 homebrew 安裝上遇到以下問題，可以使用下列解法：

error: Your local changes to the following files would be overwritten by merge:
 Library/Formula/anttweakbar.rb
 Library/Formula/assimp.rb
 Library/Formula/stunnel.rb
Please, commit your changes or stash them before you can merge.
Aborting

Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master

在 terminal 輸入下列指令：

  cd `brew --prefix`
  git remote add origin https://github.com/mxcl/homebrew.git
  git fetch origin
  git reset --hard origin/master
