Laravel 中的错误“找不到函数‘mb_output_handler’”

Question

当我在 php laravel 3.2 项目文件夹中运行以下命令时

php artisan key:generate

然后我收到此警告

警告：ob_start(): function 'mb_output_handler' not found or invalid function name in /Users/zafar/Sites/laravel-todo/laravel/core.php on line 32

在我的 phpinfo.php 中，我已经启用了 mbstring。但是，当我执行php --ri mbstring 时，它会显示Extension 'mbstring' not present.。我怎么解决这个问题？我使用 Mac OS X Lion 10.7.5。我最近使用http://php-osx.liip.ch/ 将我的 php 升级到 php 5.4.13。

更新

在我的 phpinfo 文件中，php 版本是 PHP Version 5.4.13，但是当我执行 php -v 时，它会显示以下输出

PHP 5.4.11 (cli) (built: Jan 26 2013 20:10:19)

当我运行php -i 时，它会显示以下输出

啊，来自the documentation 你引用了：

php-osx 不会覆盖 Apple 安装的 php 二进制文件，而是将所有内容安装在 /usr/local/php5 中。因此，新的 php 二进制文件位于 /usr/local/php5/bin/php 中。

尝试在您的控制台上运行/usr/local/php5/bin/php -i，看看您安装了什么。
