作曲家更新后出现Laravel错误。 “在RouteCollection.php第67行：数组到字符串的转换”

Question

我从存储库中克隆了一个Laravel项目。但是，在更新作曲家后，会弹出此错误"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，但是没有运气。

下面是我的composer.json

"require": {
    "php": ">=5.6.4",
    "barryvdh/laravel-cors": "^0.10.1",
    "barryvdh/laravel-debugbar": "^2.3",
    "barryvdh/laravel-dompdf": "0.8.2",
    "barryvdh/laravel-snappy": "0.4.1",
    "davibennun/laravel-push-notification": "dev-laravel5",
    "gloudemans/shoppingcart": "^2.3",
    "guzzlehttp/guzzle": "^6.3",

    "predis/predis": "^1.1",
    "simplesoftwareio/simple-qrcode": "~2",
    "wemersonjanuario/wkhtmltopdf-windows": "0.12.2.3",
    "willvincent/laravel-rateable": "^1.0"
},
"require-dev": {
    "fzaninotto/faker": "~1.4",
    "mockery/mockery": "0.9.*",
    "phpunit/phpunit": "~5.7"
},

更新作曲家之后：

Package phpoffice/phpexcel is abandoned, you should avoid using . 
it. Use phpoffice/phpspreadsheet instead.
Package phpunit/phpunit-mock-objects is abandoned, you should

Array to string conversion  


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

PHP工匠之后：

php artisan

删除缓存后发生相同的问题。

执行以下命令后，固定。

rm -f bootstrap/cache/config.php
