当我在 Laravel 5.1 上进行作曲家更新时，出现此错误

  [RuntimeException]

当我在缓存文件夹上追踪它时

"require-dev": {
                    "phpunit\/phpunit": "~4.5",
                    "phpunit\/dbunit": "~1.3",
                    "behat\/mink": "~1.7",
                    "behat\/mink-extension": "~2.1",
                    "behat\/mink-goutte-driver": "~1.2",
                    "behat\/mink-selenium2-driver": "~1.3",
                    "symfony\/dom-crawler": "~2.8",
                    "behat\/behat": "~3.1",
                    "sensiolabs\/behat-page-object-extension": "~v2.0.0-rc1"
                },

它不在我的 require 包上：composer.json 它来自 symfony/polyfill-mbstring 但为什么在 json 文件上他们得到这个？

"packages": {
    "shopware\/shopware": {
        "5.2.x-dev": {
            "name": …
