Answer 1

Rails 5.1 放弃了 alias_method_chain 以支持 Module#prepend； Wiselinks自 2014 年以来一直没有更新，并且与 Rails 5 不兼容。

您的选择是有限的:

1. 使用旧版本的 Rails 以便您可以使用 Wiselinks。
2. 使用 Wiselinks 以外的东西。
3. 尝试让 Wiselinks 作者更新它以适应新版本的 Rails。
4. Fork Wiselinks 并更新它以自己使用最新的 Rails。有一个 pull request for this但它已经闲置了将近一个月。

我会倾向于 (2) 除非你想 fork 它并负责维护 fork 。在 Rails 世界中四年未更新的东西可能已经被放弃了。
