无法从dist下载symfony/finder:提取ZIP文件时出错.文件已损坏

我正试图将Laravel 4.1项目克隆到Vagrant 1.6.3虚拟机上，但当我试图通过运行composer install来安装composer依赖项时，我得到了以下结果：

  - Installing symfony/finder (2.4.x-dev 4a15fc1)
    Downloading: 100%
Failed to download symfony/finder from dist: There was an error extracting the Z
IP file. Corrupt file?

我尝试了一些随机的东西，比如清除我的.gitignore文件和删除vendor/syfony/Finder目录（似乎失败了），但没有成功。是什么原因导致了这种情况，我该如何解决？
