与作曲家安装Laravel4依赖项时遇到问题

Question

我试图根据https://github.com/brunogaspar/laravel4-starter-kit中的说明安装laravel4。

下载部分之后，我试图做第2节包含：

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

当我运行最后一个命令：

php composer.phar install 

我得到的输出：

Loading composer repositories with package information 
Installing dependencies 
- Installing doctrine/lexer (dev-master bc0e1f0) 
    Cloning bc0e1f0cc285127a38c6c8ea88bc5dba2fd53e94 
- Installing doctrine/annotations (v1.1) 
Downloading:connection...

[--no-custom-installers] [--no-scripts] [--no-progress] [-v|--verbose] 
[-o|--optimize-autoloader] 

任何想法为什么我得到这个错误？
