我已经使用标准 RVM 和自制程序安装了 Ruby。我尝试安装新版本的 readline，然后强制重新安装 ruby​​-2.0.0，但这并没有解决这个问题。我可以通过搜索找到的唯一其他类似错误是丝瓜，但这对我没有帮助，因为我无法类似地修改 html5 gem。升级到 Ruby 2 时有其他人遇到过这种情况吗？

All right, turns out if I'd actually read the error message I would've realized this is a syntax error in the html5 gem, which is a dependency of xss_terminate. Replacing xss_terminate with loofah-activerecord (see xss_foliate) fixed the issue.
