作曲家更新后拉拉维尔错误。 "In RouteCollection.php line 67: Array to string conversion"

Question

我有一个从我的仓库克隆的Laravel项目。但是，在作曲家更新后，此错误会弹出"In RouteCollection.php line 67:Array to string conversion"。

我已经删除了供应商文件夹并尝试再次执行composer dump-autoload then composer update但没有运气。

下面是我的作曲家.json

"require-dev": {
    "fzaninotto/faker": "~1.4",
    "mockery/mockery": "0.9.*",
    "phpunit/phpunit": "~5.7"
},

作曲家更新后：

Package phpoffice/phpexcel is abandoned, you should avoid using . 
it. Use phpoffice/phpspreadsheet instead.
Package phpunit/phpunit-mock-objects is abandoned, you should 
avoid using it. No replacement was suggested.

Script php artisan optimize handling the post-update-cmd event 
returned with error code 1

在 php 工匠之后：

php artisan

删除缓存后也出现了同样的问题。

执行以下命令后，它被修复了。

rm -f bootstrap/cache/config.php
