Question

这是我在 Heroku 日志中看到的内容:

我尝试了所有方法，但无法真正理解为什么找不到 timeout。有什么提示吗？这是来源:https://github.com/yegor256/sixnines

Answer 1

最初，gem 名称是 timeout-extensions . RubyGems 也允许将其发布为 timeout出于未知原因。

因此，当作为 timeout 包含在 Gemfile 中时，它会阻止 Ruby 的原生 timeout 模块，该模块定义了 Timeout::Error.

因此，Gemfile 中的行应该是

gem 'timeout-extensions'

代替

gem 'timeout'
