使用Laravel 5.4和PHP 7进行作曲家更新“类名必须是有效对象或字符串”

前端之家收集整理的这篇文章主要介绍了使用Laravel 5.4和PHP 7进行作曲家更新“类名必须是有效对象或字符串”前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
因此,有一些线程,但没有完全相同的问题.基本上我从5.1升级PHP 5.4,从5.6升级PHP 7,我现在收到此错误消息.
PHP Fatal error:  Uncaught Error: Class name must be a valid object or a string in /var/www/dev1/vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.PHP:96

这对我来说似乎很奇怪的原因是错误是在我的app /我编辑过的实际laravel文件中.当我运行composer update或每次尝试访问我的任何网页时都会发生此错误.以下是作曲家更新的完整转储,任何想法?

[root@dev1 dev1]# composer update
> PHP artisan clear-compiled
PHP Fatal error:  Uncaught Error: Class name must be a valid object or a string in /var/www/dev1/vendor/laravel/framework/src/Illuminate/Foundation/Exceptions/Handler.PHP:96

升级到Laravel 5.4时,我遇到了类似的错误.问题是Laravel仍在加载bootstrap / cache / compiled.PHP(尽管它说它不再被框架使用).删除文件解决您的问题.

From the docs

If it exists,you may delete the bootstrap/cache/compiled.PHP file. It is no longer used by the framework.
