使用Vagrant时出现意外的Laravel 5错误

Question

我正在为我的API使用vagrant + puppet + capistrano + Laravel 5来签署一个项目结构，我从我的本地部署到舞台上已经有一个月了，但是突然从昨天开始我不能执行我的本地环境。

当我启动我的流浪者机器没有显示任何错误，我已经删除了框，实例，重新安装VirtualBox和流浪者，仍然是同样的错误，最奇怪的事情是在其他计算机上运行良好，没有问题。

当我在"Generating autoload files“中使用composer更新/安装时，总是出现错误。

我已经重新安装了很多次，但仍然是同样的错误。

VirtualBox: 4.3.28
Laravel: 5.0.22
Vagrant: 1.7.2
Vagrant Box: http://puppet-vagrant-boxes.puppetlabs.com/centos-65-x64-virtualbox-puppet.box

Answer 1

你的项目中有.dotenv文件吗？如果是，请检查您是否有一致的行尾(unix/windows/mac)。

Answer 2

您应该检查.env文件，或者最好使用您喜欢的集成开发环境重新生成它。DotEnv.php第51行试图从.env文件中剥离注释，但文件中存在编码错误。
