【中文标题】哎呀，看起来像出事了。尝试在内置服务器上运行时 Laravel 5 中的错误【英文标题】：Whoops, looks like something went wrong. error in Laravel 5 when trying to run on built in server 【发布时间】：2016-02-20 01:55:25 【问题描述】：

我从我的 git repo 中克隆了一个项目并尝试执行以下命令

php artisan serve

我得到了

Laravel 5 Failed opening required bootstrap/../vendor/autoload.php

所以我跟着这个答案

Laravel 5 Failed opening required bootstrap/../vendor/autoload.php

然后做了composer install

在我这样做之后

php artisan serve

服务器启动正常，但在 chrome 浏览器中出现以下错误

Whoops, looks like something went wrong. error in Laravel 5

任何可能出现问题的提示

更新

我打开文件夹 storage/logs/ 有一个文件叫laravel 这是它的转储

` 感谢和问候

【问题讨论】：

通常错误之后是堆栈跟踪，也许您也可以发布它？ 我只是收到此错误，即使我无法理解为什么会发生这种情况， 查看日志，这些应该在storage/logs @Jerodev 好的，我会看到 @Jerodev 我用日志转储更新了我的问题 【参考方案1】：

您的项目根目录中似乎没有.env 文件。此文件包含您的应用程序的所有全局设置。

通常在您的应用程序的根目录中有一个.env.example 文件。将此文件重命名为 .env 并将 APP_KEY 属性更改为随机字符串以提高安全性。

【讨论】：

好吧，我已经解决了。很多事情都必须改变，包括 .env 文件:)。不管怎样，我会接受你的回答【参考方案2】：
    将 .env.example 重命名为 .env 转到 bootstrap=>app.php 并取消注释 $app->withEloquent(); 确保 APP_DEBUG=true 在 .env 文件中。现在它可以工作了。
