Symfony 从 4.2 更新到 4.3 导致 Web Profiler 崩溃

Question

我运行了composer update，现在收到了大量弃用警告:

> [2019-06-03 18:08:41] request.INFO: Matched route "_wdt".
> {"route":"_wdt","route_parameters":{"_route":"_wdt","_controller":"web_profiler.controller.profiler::toolbarAction","token":"9354bc"},"request_uri":"http://local
> host:8080/_wdt/9354bc","method":"GET"} [] [2019-06-03 18:08:42]
> request.CRITICAL: Uncaught PHP Exception Twig\Error\RuntimeError:
> "Impossible to access an attribute ("nb_errors") on a string variable
> ("O:39:"Symfony\Component\VarDumper\Cloner\Data":6:{s:45:"ymf
> ony\Component\VarDumper\Cloner\Data

Web Profiler 工具栏因以下错误而损坏:

An error occurred while loading the web debug toolbar.

然而，当我执行 bin/console --version 时，我得到:

Symfony 4.3.0 (env: dev, debug: true)

什么给了？ composer.json 文件如何让 Composer 甚至能够更新到 4.3？

这是我当前的composer.json:

打开composer.json。将所有 4.2 引用更新为 4.3。您可能有 symfony/web-profiler-bundle 为 4.2 而不是 4.3。保存，然后 Composer 更新。
