Ruby 2.4 中出现 Unicorn 类型错误时该怎么办

Question

我将 ruby​​ 从 2.1 升级到 2.4(ruby24, ruby​​24-devel), bundler(version: 1.17.3), nokogiri(version: 1.6.8), rails(version: 4.0.1), unicorn(version: 5.0 .1），therubyracer（版本：0.12.3）。 有如下故障：

不知道有没有人知道该怎么做

Answer 1

这来自rails 使用的activesupport gem。所以您的rails 和ruby 版本之间存在版本兼容性问题。如果您想升级您的ruby，有时您应该相应地升级您的rails 版本。所以有两种方法可以解决这个问题。逐步降级 ruby​​ 版本或升级 rails 版本。
