【问题描述】：

我正在使用 Symfony 5.X，它是在 docker 上的全新安装，带有图像“bitnami/symfony”。我也使用“bitnami/nginx”和“bitnami/php-fpm”。除了 Web Profiler 工具栏外，所有功能都很好。

我过去 2 天在 Google 上寻找解决方案，但没有任何效果。我可以访问 url /_profiler/ 但是如果我点击一个令牌来查看一些详细信息，我会收到一个错误 500。

TypeError:

我认为正是由于这个原因，我的工具栏显示“加载网络调试工具栏时发生错误”。

这是我为这个网站设置的 Nginx 配置文件：

server {
    server_name simtp.local www.simtp.local;
    root /app/simtp/public;
    listen 0.0.0.0:8080;

    location / {
        # try to serve file directly, fallback to index.php
        try_files $uri /index.php$is_args$args;
        #try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    # optionally disable falling back to PHP script for the asset directories;
    # nginx will return a 404 error when files are not found instead of passing the
    # request to Symfony (improves performance but Symfony's 404 page is not displayed)
    # location /bundles {
    #     try_files $uri =404;
    # }

    location ~ ^/index\.php(/|$) {
        fastcgi_pass phpfpm:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;

        # optionally set the value of the environment variables used in the application
        # fastcgi_param APP_ENV prod;
        # fastcgi_param APP_SECRET <app-secret-id>;
        # fastcgi_param DATABASE_URL "mysql://db_user:db_pass@host:3306/db_name";

        # When you are using symlinks to link the document root to the
        # current version of your application, you should pass the real
        # application path instead of the path to the symlink to PHP
        # FPM.
        # Otherwise, PHP's OPcache may not properly detect changes to
        # your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
        # for more information).
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $document_root;
        # Prevents URIs that include the front controller. This will 404:
        # http://domain.tld/index.php/some-path
        # Remove the internal directive to allow URIs like this
        internal;
    }

    # return 404 for all other php files not matching the front controller
    # this prevents access to other php files you don't want to be accessible.
    location ~ \.php$ {
        return 404;
    }

    #error_log /opt/bitnami/nginx/project_error.log;
    #access_log /opt/bitnami/nginx/project_access.log;
}

我的 docker-compose 文件：

我在论坛上看到有人用 symfony/apache-pack 包解决了这个问题，但我不想使用 Apache，因为我已经有 Nginx。

我没有更多的想法，我已经尝试了很多东西，如果有人可以帮助我，那就太好了。

【问题讨论】：

你有完整的堆栈跟踪吗？这个错误具体发生在哪里？从错误消息来看，我不会认为这是您的 nginx/docker-compose 设置的问题，而是 php 代码中的错误，无论是 Symfony 还是您的。
当我转到 url /_profiler 时发生错误（当我单击令牌时），例如 /_profiler/3bba77。我刚刚编辑了我的帖子以添加堆栈跟踪。我想指定我的项目是全新安装的，我的控制器只呈现一个测试视图（使用 make:controller 启动的控制器）。视图包含所有最小代码（html、body 等）

【解决方案1】：

这是 Symfony 5.0.0 中的一个错误，应该已经在 5.0.1 中修复。您可以看到配置更改，这可能会在此处解决此问题：https://github.com/symfony/symfony/compare/v5.0.0...v5.0.1#diff-414443648aa78565f2158b8154a1ff8e

最好的方法是运行composer update

【讨论】：

我刚刚在他们的 Github 上的帖子中看到了这一点，也感谢您的宝贵时间！升级到 5.0.1 是有效的解决方案！

【解决方案2】：

将 Symfony 5.0.0 更新到 5.0.1 对我不起作用，因为我已经在 5.0.1 中了。解决方案更简单，只需从 Symfony 项目中删除 var/cache 文件夹即可使工具栏再次工作。
