symfony - Symfony 4.2 中没有根节点的树构建器

Question

我将我的 Symfony 项目从 4.1 升级到 4.2，并在分析器中收到了 12 次此通知:

A tree builder without a root node is deprecated since Symfony 4.2 and will not be supported anymore in 5.0.

并且日志的跟踪是:

{▼
  /home/user/foo/bar/project/vendor/symfony/config/Definition/Builder/TreeBuilder.php:30 {▼
    › if (null === $name) {
    ›     @trigger_error('A tree builder without a root node is deprecated since Symfony 4.2 and will not be supported anymore in 5.0.', E_USER_DEPRECATED);
    › } else {
  }
  /home/user/foo/bar/project/vendor/sensio/framework-extra-bundle/DependencyInjection/Configuration.php:32 {▼
    › {
    ›     $treeBuilder = new TreeBuilder();
    ›     $rootNode = $treeBuilder->root('sensio_framework_extra', 'array');
  }
}

如何解决这个问题？

该问题已在 sensio/framework-extra-bundle 中修复:

您必须等待下一次更新(更高的 5.2.2)。
