我不知道如何解决这个问题，无法在网上找到信息来帮助，但我发现这是与nio4r宝石有关，但没有太多其他的。请帮助，让我知道我能做什么，任何更多的信息。我用的是fedora, linux.

当本机扩展编译不正确时，就会出现这个问题。您需要重新编译nio4r gem的本地扩展。这个问题有很多很多可能的原因:
- 您通过传入无效参数来编译扩展(例如，告诉它为错误的体系结构编译)
- 您在另一个操作系统上编译扩展，然后手动将它们移动到此系统
- 您在过去编译了扩展，然后进行了主要的系统升级或操作系统更改，然后尝试继续使用以前编译的扩展
还有其他可能的原因，但最直接的解决方案是重新编译扩展:
bundle pristine nio4r
如果您仍然有这个问题，那么请确保您的打包器平台是ruby而只有ruby:
bundle config force_ruby_platform true
这将有以下效果:
忽略当前机器的平台，只安装
ruby平台宝石。因此，带有本地扩展的gem将从源代码编译。
然后重试bundle pristine nio4r强制重新编译。
