我是laravel的新手，我通过作曲家安装Laravel Socialite并在config / app.php中进行必要的更改但是当我运行我的应用程序时它会给出空白页面，我的app.php文件是

请帮助我摆脱这个问题。
答案 0 :(得分：0)
tl; dr：检查存储/日志的文件权限。
我和Socialite遇到了同样的问题，我发现它是由Laravel的日志轮换引起的。它每天都会生成一个新的日志文件，但是当您从命令行（phpunit或artisan）运行时，它将使用您的Unix用户名而不是www-data生成此文件。
您的www-data用户（或任何网络服务器的用户）需要写入此文件的权限才能写入错误日志。空白屏幕是由Logger在显示堆栈跟踪视图之前尝试记录错误引起的。
由于脚本没有从文件系统中找到爱，因此Web服务器会在有机会告诉您发生了什么之前停止执行。因此，即使您的配置设置为调试，您也无法获得Stack Trace或Laravel的日志。
您可以在网络服务器的错误日志中看到它（如果您在Linux中，它通常会转到/var/log/{server_name}/error.log - 或检查您的虚拟服务器日志记录配置如果路径不同）。
修复权限问题后，您可以看到跟踪视图，找出真正的错误来源，然后进行修复。
如果您不想每天都重新修复此权限问题，只需将您的www-user添加到您的用户名组，如下所示：
sudo usermod -a -G yourusername www-data
或者（如果您愿意）您可以配置Monolog将当前用户名添加到日志文件中，如下所示： Laravel daily log created with wrong permissions
