我正在尝试使用以下命令安装 Composer:
curl -s https://getcomposer.org/installer | php
我收到了这个错误:
PHP Warning: Directive 'safe_mode' is deprecated in PHP 5.3 and greater in Unknown on line 0
#!/usr/bin/env php
Some settings on your machine may cause stability issues with Composer.
If you encounter issues, try to change the following:
Your PHP (5.3.2-1ubuntu4.18) is quite old, upgrading to PHP 5.3.4 or higher is recommended.
Composer works with 5.3.2+ for most people, but there might be edge case issues.

任何想法?

我刚刚在我的电脑上尝试过:
[alexus@wcmisdlin02 ~]$ curl -s https://getcomposer.org/installer | php
#!/usr/bin/env php

Composer successfully installed to: /home/alexus/composer.phar
Use it: php composer.phar
[alexus@wcmisdlin02 ~]$ php -v
PHP 5.3.3 (cli) (built: Jun 27 2012 14:13:03)

首先尝试更新您的 PHP 包,然后再试一次。
似乎你这边缺少一些 php 扩展,下面是我在我的这边安装的:
[alexus@wcmisdlin02 ~]$ rpm -qa | grep ^php
