Laravel执行migrate操作提示”Class not found”怎么解决

Jun 08, 2016 pm 05:19 PM
autoload composer migrate nbsp

Class not found提示是类没有找到了,没有找到对应的类我们可以检查是不是哪里配置或调用有问题了,下面我们来看一篇关于Laravel执行migrate操作提示”Class not found”问题解决办法了,具体的如下所示。

<script>ec(2);</script>

使用Laravel的artisan命令工具执行migrate操作,提示”Class not found”的错误,但是这个migrate类文件是存在的,如遇到这个问题,可执行以下composer dump-autoload,问题得到解决。

一开始报错如下:


[root@iZ94r80gdghZ tanteng.me]# php artisan migrate:reset
                                                          
[Symfony\Component\Debug\Exception\FatalThrowableError] 
Fatal error: Class 'CreateAttachmentTable' not found

无论执行migrate什么操作都提示类找不到。

执行composer dump-autoload后,再次运行migrate操作,一切正常。

[root@iZ94r80gdghZ tanteng.me]# composer dump-autoload
Generating autoload files
[root@iZ94r80gdghZ tanteng.me]# php artisan migrate:reset

composer dump-autoload的作用

composer dump-autoload命令的作用是优化自动加载,当把代码部署到生产环境中,或者增加删除了自动加载文件夹里的类文件,需要执行一下自动加载命令,这样自动加载才会起作用。
