无法使用composer安装Laravel4依赖项

Question

我尝试按照https://github.com/brunogaspar/laravel4-starter-kit中的说明安装laravel4。

在下载部分之后，我尝试执行第2部分，其中包含：

    cd your-folder
    curl -s http://getcomposer.org/installer | php
    php composer.phar install

当我运行最后一个命令时：

    php composer.phar install

我得到了输出：

知道我为什么会收到这个错误吗？
