我一直在尝试使用
curl -sS https://getcomposer.org/installer | php
命令，它给出了以下错误：
#!/usr/bin/env php
Some settings on your machine make Composer unable to work properly.
Make sure that you fix the issues listed below and run this script again:
The suhosin.executor.include.whitelist setting is incorrect.
Add the following to the end of your `php.ini` or suhosin.ini (Example path [for Debian]: /etc/php5/cli/conf.d/suhosin.ini):
suhosin.executor.include.whitelist = phar
The php.ini used by your command-line PHP is: /etc/php5/cli/php.ini
If you can not modify the ini file, you can also run `php -d option=value` to modify ini values on the fly. You can use -d multiple times.
我尝试检查上面提到的文件，但没有一个真正起作用。接下来我该怎么办？
