未找到接口 Matcher\RequestMatcherInterface'

Question

我正在尝试将我的 Symfony 应用程序部署到虚拟主机并收到此错误

 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，所以我复制了除 var 和 test 之外的所有文件夹。然后 .env 和 composer.json 到 /subdom/dev （这个子域使用正常的 HTML 索引）

使用php 7.3。 Composer.json

编辑：我试过 echo interface_exists("Symfony\Component\Routing\Matcher\UrlMatcherInterface"); 并且它 returns 1。但是错误仍然存在。

我不知道下一步要看哪里。

Answer 1

好的，给读到这里的你。不要与错误争论。如果错误说它没有找到它是真的并修复它。 Filezilla 出现问题，一些文件未正确传输（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 returns 在你的情况下是真的...
