ruby-on-rails - 将应用程序部署到 Heroku 并获取 "no such file to load -- will_paginate"

Question

我正在 Heroku 上运行 Ruby 1.8.6、Rails 1.2 应用程序。我正在使用Aspen stack 。当我尝试部署时，应用程序崩溃了。

这是我在日志中的内容

编辑:根据建议，我已要求 Heroku 支持人员安装 gem will_paginate。我会随时向大家通报结果。

Answer 1

您缺少 will_paginate gem。

如果 will_paginate 甚至支持 1.8.6，您需要将其添加到您的 .gems list 中。如果您使用 Bundler，请在部署之前将其添加到您的 Gemfile 和 bundle 中。
