【问题描述】：

我将 composer.json 中的 Symfony 版本从 3.3 更改为 3.4，然后运行更新命令。

使用命令“composer update”升级到 v3.4 后，显示此错误：

我的 PHP 版本是 5.6.30

我搜索了网络和 Symfony 文档，但没有找到与此问题相关的内容。

【解决方案1】：

我通过将“provider:user_db”添加到“simple_form”来解决这个问题。也许这对某人有帮助。

simple_form:
    provider: user_db
    authenticator: courses_authenticator
    check_path: login_check
    login_path: login
