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：

activesupport这来自rails. rails因此，您的版本和版本之间存在版本兼容性问题ruby。如果你想升级你的ruby，有时你应该rails相应地升级你的版本。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。
