包括安装 PEAR/PHPUnit 的路径问题

我正在按照这个 http://www.newmediacampaigns.com/page/install-pear-phpunit-xdebug-on-macosx-snow-leopard 安装PEAR/PHPUnit。我在使用包含路径时遇到问题。

一些背景信息：

Farooqs-MacBook-Pro:bin fyousuf$ which php
/usr/bin/php
Farooqs-MacBook-Pro:bin fyousuf$ which pear
/usr/local/bin/pear
Farooqs-MacBook-Pro:bin fyousuf$ which phpunit
/usr/local/bin/phpunit

我认为我搞砸的部分是我上面发布的链接中的"更新 PHP 包含路径"。

这是我的php.ini文件中的内容：

    ; UNIX: "/path1:/path2"
    ;include_path = ".:/php/includes"
    include_path = ”/usr/local/bin/PEAR:/php/includes”
    ;
    ; Windows: "'path1;'path2"
    ;include_path = ".;c:'php'includes"
    include_path = ”/usr/local/bin/PEAR:/php/includes”
    ;
    ; PHP's default setting for include_path is ".;/path/to/php/pear"
    ; http://php.net/include-path`

当我尝试使用 phpunit 运行硒测试时，出现此错误：

   phpunit functions.php
   PHP Warning:  require_once(File/Iterator/Autoload.php): failed to open stream: No such            
   file or directory in /usr/local/pear/share/pear/PHPUnit/Autoload.php on line 64
   PHP Fatal error:  require_once(): Failed opening required 'File/Iterator/Autoload.php'         
   (include_path='”/usr/local/bin/PEAR:/php/includes”') in       
   /usr/local/pear/share/pear/PHPUnit/Autoload.php on line 64

新编辑：

我安装了 PHPUnit：

Farooqs-MacBook-Pro：echo360-5.0 fyousuf$ sudo pear install phpunit/PHPUnitphpunit/PHPUnit 已经安装，与发布的版本 3.7.27 相同安装失败

但是当我在终端中键入phpunit时，我得到与以前相同的错误：

PHP 警告：require_once(File/Iterator/Autoload.php(：无法打开流：第 64 行的/usr/local/pear/share/pear/PHPUnit/Autoload.php 中没有这样的文件或目录PHP 致命错误：require_once((：打开失败需要"文件/迭代器/自动加载.php"(include_path='.：/usr/local/PEAR：/php/include'( 在/usr/local/pear/share/pear/PHPUnit/Autoload.php 第 64 行
