php - 拉维尔 5.1 : Class cache does not exist

Question

您好，亲爱的提供者，为许多问题提供了许多答案!

我现在使用 SO 一段时间了(5 年多)，尽管主要是被动的。这次我遇到了一个让我彻夜难眠却无法解决的问题。

这就是它的全部内容。我将 Laravel 5.1 与 Redis(缓存和 session )结合使用。遗憾的是，当我切换到 nginx 并升级一些软件包(composer)时，一切都停止了。 Laravel 打印出以下异常:

ReflectionException in Container.php line 737:

at Kernel->handle(object(Request)) in index.php line 54

值得一提的是:我安装了predis，为nginx打开了resty。 奇怪的是，如果我使用文件缓存驱动程序，它运行得很好，没有任何异常。如果我通过 cli ping redis，我会得到正确的“PONG”响应，但我不知道现在该做什么..(除了不使用 redis 驱动程序；-))。

也许值得一提的是，如果我通过 cli 运行 artisan 命令，它会给出不同的错误:

PHP Catchable fatal error:  Argument 2 passed to         Illuminate\Routing\UrlGenerator::__construct() must be an instance of Illuminate\Http\Request, null given, called in /var/www/html/*laravel-project*/vendor/laravel/framework/src/Illuminate/Routing/RoutingServiceProvider.php on line 62 and defined in /var/www/html/*laravel-project*/vendor/laravel/framework/src/Illuminate/Routing/UrlGenerator.php on line 99

因此，我认为我的 nginx 虚拟主机配置可能有问题(这是服务器设置的主要更改)。虚拟主机看起来像这样:

server {
    listen       80 default_server;
    #listen      [::]:80 default_server ipv6only=on; ## listen for ipv6
    server_name  *MY_SERVER_NAME*;
    root         /sites/*LARAVEL_PROJECT*/public;
    charset utf-8;

    # Elastic search api config
    location /elastic {
        proxy_pass http://localhost:9200;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }


    #auth_basic_user_file /etc/nginx/htpasswd.users;
    # Kibana web access
    location /kibana {
        auth_basic "Restricted Access";
        auth_basic_user_file /etc/nginx/htpasswd.users;
        proxy_pass http://localhost:5601;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }

    # entry point to the Laravel project
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    access_log /var/log/nginx/laravel-project-access.log;
    error_log  /var/log/nginx/laravel-project-error.log error;

    sendfile off;
    client_max_body_size 100m;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        fastcgi_buffer_size 16k;
        fastcgi_buffers 4 16k;
    }

    location ~ /\.ht {
        deny all;
    }
}

有什么想法或建议吗？

提前致谢!

就我而言(laravel 5.2)，问题出在自定义服务提供程序中，我在 register() 而不是 boot() 函数中声明了自定义响应宏。

将宏移至 boot() 后，错误消失。
