localhost:1nbox myusername$ sudo curl -s http://getcomposer.org/installer | phpmamp
#!/usr/bin/env php
All settings correct for using Composer
PHP Fatal error: Uncaught exception 'RuntimeException' with message 'Unable to write bundled cacert.pem to: /Users/myusername/.composer/cacert.pem' in -:403

我的.bash_profile有：
alias phpmamp='/Applications/MAMP/bin/php/php5.6.2/bin/php'
正如上面@TotalWipeOut发布的，这个命令有效：
curl -s http://getcomposer.org/installer | sudo /Applications/MAMP/bin/php/php5.6.2/bin/php
我能够成功地用MAMP PHP安装作曲家。
