Drupal 9试图使用devel生成内容时发生致命错误

Question

几天前我刚安装了Drupal 9.4.8。我按照关于如何从这段视频生成临时内容以进行测试的说明，收到了一个致命的错误。我需要知道如何修复错误，以便生成一些临时内容。

再生产的步骤

1安装开发模块

使用composer安装模块。根据文档，这应该适用于Drupal 9。

composer require 'drupal/devel:^5.0'

在drupal管理/模块控制面板中，安装Devel和Devel生成。

2转到drupal /config以生成内容

访问admin/config并单击GenerateContent选项。选择所需的内容类型--在我的示例中，自定义事件和用户组内容类型。我指定了以下设置：

• 生成50个节点
• 一年前
• 每个标题2个字

所有其他设置都是默认设置。

单击生成。

--这会产生问题

在我的浏览器中，我看到的是：

网站遇到了一个意外的错误。请稍后再试。

我查看了apache日志并看到了以下错误消息：

我一点也不确定，但似乎有一些发展的先决条件，但我没有。如果有人告诉我修复这个致命错误的最佳方法，我将不胜感激。

Answer 1

正如@BaldeBinos在注释中所建议的，我使用composer作为在此描述安装drush。这涉及通过CLI进行连接，将我的工作目录切换到安装了drupal的位置，并运行一个composer命令：

cd /var/www/mydrupal
composer require drush/drush

它并下载和安装各种可能的20个档案，其中最后一个是drush/drush：

这似乎是所需的全部，但请注意，drush并没有出现在我安装的/admin/模块中。在这一个composer命令之后，我能够在我原来的文章中重复这些步骤，临时/测试内容就被成功地生成了。
