Question

我在安装 wiselinks gem 后遇到了这个问题。

Ruby 版本：Ruby 2.4.0

Rails 版本：Rails 5.1.3

rake 中止！

Answer 1

Rails 5.1 放弃了alias_method_chain，取而代之的是Module#prepend； Wiselinks 自 2014 年以来未更新，与 Rails 5 不兼容。

您的选择有限：

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 作者更新它以使用新版本的 Rails。
4. Fork Wiselinks 并自行更新以使用最新的 Rails。有一个pull request for this，但它已经闲置了将近一个月。

我倾向于 (2) 除非你想分叉它并负责维护分叉。在 Rails 世界中四年没有更新的东西可能已经被放弃了。
