找不到Interface Matcher \ RequestMatcherInterface'

Question

我正在尝试将Symfony应用程序部署到Webhosting并出现此错误

 Fatal error: Interface 'Symfony\Component\Routing\Matcher\RequestMatcherInterface' not found in /data/web/virtuals/201283/virtual/www/subdom/dev/vendor/symfony/routing/Matcher/UrlMatcher.php on line 29

我的虚拟主机没有SSH访问权限，因此我复制了除var和test以外的所有文件夹。然后将.env和composer.json移至/ subdom / dev（该subdom与常规HTML索引一起使用）

使用php 7.3。Composer.json

编辑：我尝试过echo interface_exists("Symfony\Component\Routing\Matcher\UrlMatcherInterface");，它返回1。但是错误仍然在这里。

我不知道下一步去哪里。

Answer 1

好，给你，谁读了这个。不要与错误争论。如果错误，则说明找不到它，并进行修复。 Filezilla发生了某些情况，并且某些文件未正确传输（创建时大小为0B）。所以我手动复制了它们。

Answer 2

根据您的composer.json，缺少"symfony/routing": "4.3.*",，因此Symfony路由组件不可用。但是，我不明白为什么interface_exists在您的情况下返回true ...
