【问题描述】：
上周由于 bash “易受攻击的问题”，我在 cygwin 中进行了更新。
之后，我无法再编译 sass。
我尝试重新安装 ruby，在某些安装失败并重新安装 cygwin 后，我安装了它并使用
“gem update --system”
进行了更新
它运行，但是当我尝试安装指南针时，我收到以下消息：

我尝试安装 ffi（“gem install ffi”和“gem install ffi --pre”），我得到了同样的信息
这里是日志（.gem/ruby/extensions/x86_64-cygwin/ffi-1.9.5/gem_make.out）

我真的很沮丧！！'

我知道这已经有一段时间了，但是你找到解决这个问题的方法了吗？
