为什么我在安装 spree 时在 Spree::UserSessionsController#new 中出现 SyntaxError？

Question

我有一个旧的 rails 应用程序，我现在重新打开它，想弄清楚为什么我会收到此语法错误。我确信它与 ruby 或 rails 版本

有一些联系

gem 'spree', '3.0.0'
gem 'spree_gateway', github: 'spree/spree_gateway', branch: '3-0-stable'
gem 'spree_auth_devise', github: 'spree/spree_auth_devise', branch: '3-0-stable'
gem 'spree_static_content', github: 'spree-contrib/spree_static_content', branch: '3-0-stable'

在尝试登录或尝试进入管理面板之前它一直有效。每次都有同样的错误：

问题是第 5 行使用的是旧语法，您可能使用的是更新版本的 ruby。

prepend_before_filter only: [:create, :destroy] { request.env["devise.skip_timeout"] = true }

应该是（注意()）

prepend_before_filter(only: [:create, :destroy]) { request.env["devise.skip_timeout"] = true }

在这里设计更改：
