Answer 1

问题在于Sonata Formatter，我遇到了同样的问题，所以我只是评论从config.yml导入其配置的行

imports:
- { resource: parameters.yml }
- { resource: security.yml }
- { resource: fos_user.yml }

# Sonata Bundles
- { resource: sonata/sonata_admin.yml }
- { resource: sonata/sonata_block.yml }
- { resource: sonata/sonata_media.yml }
#- { resource: sonata/sonata_formatter.yml }
- { resource: sonata/sonata_news.yml }
- { resource: sonata/sonata_cache.yml }
- { resource: sonata/sonata_seo.yml }
- { resource: sonata/sonata_notification.yml }
- { resource: sonata/sonata_user.yml }

修改

将它放在 composer.json ：
中的必需库中
"twig/twig": "1.11.1"

Answer 2

或者您可以按照格式化程序包配置设置

进行操作

sonata_formatter:
    formatters:
        markdown:
            service: sonata.formatter.text.markdown
            extensions: []

        text:
            service: sonata.formatter.text.text
            extensions: []

        twig:
            service: sonata.formatter.text.twigengine
            extensions: [] # Twig formatter cannot have extensions

由于扩展已经初始化，因此无法注册扩展“sandbox”
