High Sierra 10.13.1 和 Rails 有问题吗？

Question

我尝试在高山上安装 Rails，但一直收到 "Failed to build gem native extension" 错误。

checking for sys/epoll.h... no

^ 这就是我需要看的。我不确定这是否是新 OS 的问题...可能是 nio4r-2.1.0 的问题？

Answer 1

这是 High Sierra 的问题，xCode.I 首先将我的机器重新格式化为 El Capitan，安装 Rails 没有任何问题。然后在另一台装有 High Sierra 的机器上，我也遇到了 Rails.

的问题

更新到xCode9.2后，我成功安装了Rails5.1.4.

谢谢大家
