ruby - Gem :: Ext :: BuildError：错误：无法构建gem原生扩展--nio4r

我正在尝试在我的gemfile及其依赖项中安装所有gem，因此只需运行Bundler（bundle或bundle install）。在使用本机扩展安装nio4r 1.1.1时失败，下面是登录gem_make.out。

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

extconf failed, exit code 1

我可以看到捆绑器正在检查unistd.h并且在那时失败了。我确保此标头在PATH中可用，并且还为我的版本安装了ruby devkit。执行gem install nio4r也会出现同样的错误。
