小牛PHP版本问题

我刚刚运行下面的命令来更新我的系统上的PHP（两次，忘记我之前运行过它）。

curl -s http://php-osx.liip.ch/install.sh | bash -s 5.5

产量

但是，当我跑 php --version 我明白了

PHP 5.4.17 (cli) (built: Aug 25 2013 02:03:38) 
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies

which php tells me `/usr/bin/php`

如何让我的系统使用5.5？

尝试

/usr/local/php5/bin/php --version

如果您希望在命令行键入php时该php成为默认值，请运行以下命令：

echo "alias php='/usr/local/php5/bin/php'">>~/.bash_profile

然后关闭终端并打开一个新终端或运行

. ~/.bash_profile
