“rake routes”导致语法错误：time_zone.rb 循环参数参考 - 现在

Question

我正在尝试运行 rake routes，但出现此错误（请参阅下面的完整堆栈跟踪）：

rake aborted!
SyntaxError: /usr/local/lib/ruby/gems/2.7.0/gems/activesupport-3.2.12/lib/active_support/values/time_zone.rb:270: circular argument reference - now

我该如何解决这个问题？

尝试解决问题

我试过bundle install和bundle update，都运行成功了。但是，这并没有解决由rake routes 导致的循环参数错误。

根据发行说明，Rails 3.2 仅支持 Ruby 1.8.7 和 Ruby 1.9.2。您使用的是 Ruby 2.7.1。

请注意，社区自 2016 年起不再支持 Ruby on Rails 3.2，自 2014 年起社区不再支持 Ruby 1.8.7 和 1.9.2。

有一家公司销售 Ruby on Rails 的长期支持：https://railslts.com/。您可以以每月 150 美元的价格购买 Ruby on Rails 3.2 的支持计划，而且他们的版本也支持 Ruby 2.5。 Ruby 2.5 不再由社区积极开发，但在 2021 年 3 月 31 日之前，它仍会收到社区提供的重要安全修复。
