symfony6安装KnpMenuBundle

Question

我想将KnpMenuBundle安装到一个空的Symfony项目(--webapp项目)中。

我从KnpMenuBundle文档中执行步骤，但它不起作用。

配置

• symfony 6.1.7
• KnpMenuBundle下载: 3.2

以下是我的不同档案：

备注：

• 当我安装KnpMenuBundle时，config/packages/knp_menu.yaml不存在，我必须创建它并粘贴到代码中。
• src/Menu文件夹不存在，我必须用Builder.php创建它并粘贴代码。
• 当我将{{ knp_menu_render('App:Builder:mainMenu') }}添加到我的templates/index/index.html.twig中时，我得到了错误： 在模板的呈现过程中抛出了一个异常("Bundle "App“不存在或它未启用。也许您忘记将它添加到"App\Kernel.php”文件的“App\Kernel.php()”方法中？“)。

如果你有任何想法，线索，或其他什么，我在听，因为我不知道哪里错了。

Answer 1

我使用方法b:菜单生成器作为服务，没有任何问题。

看看文件页。所以我建议你也这么做。
