Laravel - re-installing app : 'ServiceProvider not found'

Question

I tried to upgrade my app from 5.1 to 5.2 & ran into some issues. I needed my app back in a working state so i re-uploaded the old version I had backed up on my system. However it is still not working as it was before and Im getting this error :

FatalErrorException in ProviderRepository.php line 146: Class 'Lavary\Menu\ServiceProvider' not found

the same error appears when trying to run any composer commands

$ composer update
> php artisan clear-compiled



  [Symfony\Component\Debug\Exception\FatalThrowableError]
  Fatal error: Class 'Lavary\Menu\ServiceProvider' not found



Script php artisan clear-compiled handling the pre-update-cmd event returned with an error


  [RuntimeException]
  Error Output:

Answer 1

Lavary软件包存在问题。尝试再次配置。

Answer 2

I used:

composer update --no-scripts

& its working without error now.

Answer 3

我有一个建议，请尝试从“提供程序”部分的config / app.php中删除Lavary \\ Menu \\ ServiceProvider，然后运行composer，安装软件包Lavary，然后将此行添加回app \\ config.php文件中。
