【问题描述】：

我正在尝试使用 acts_as_textcaptcha 在我的 Devise 注册表单中添加垃圾邮件保护，但由于某种原因它不会显示在我的表单中。

基于How To: Use Recaptcha with Devise。我的 Rails 6 博客应用程序可在此处克隆：https://github.com/anonymous-donor/blog-with-textcaptcha

谢谢！

【解决方案1】：

对不起，如果我错了，你能说这是gem 'acts_as_textcaptcha', '~> 4.5'吗？我在您提供的链接中找不到这个：https://github.com/ambethia/recaptcha。如果有任何问题，请关注该 gem 并回复。您可以参考同一页面来配置设计：https://github.com/heartcombo/devise/wiki/How-To:-Use-Recaptcha-with-Devise。谢谢。

你在说什么？

【解决方案2】：

原来我必须在 config/environments/development.rb 中将 config.cache_store = :null_store 设置为 config.cache_store = :memory_store 才能在开发模式下工作。
