我正在尝试在豹子上安装Jekyll，但无法正常工作。我取得的最大进步是能够在终端机上运行gem install jekyll，但随后出现错误make failed, exit code 2。
由于cert / ssl错误，我无法从rbenv或rvm安装ruby，这就是为什么我从源代码安装了ruby的原因。我可以通过brew install ruby安装，但是得到相同的结果。
我看过许多其他有关make failed错误的帖子，该错误通常与多个Ruby版本有关。这些页面上的答案都无效，因为我已经从源代码安装了所有内容（brew，rbenv或rvm从未安装过ruby）。
我已经尝试使用上述所有方法安装ruby，但出现了相同的错误。
每次我测试从源代码或从Tigerbrew / homebrew安装Ruby时，我都会干净安装Leopard + Xcode等新系统。我也在多台机器上进行了尝试。
我刚刚将rubygems更新为版本3.0.2，该版本修复了安装gems时出现的一些证书错误，但尚未解决问题。
还有什么我可以做的才能使它正常工作吗？
下面是我运行gem install jekyll时来自Terminal的输出。

所以我发现Make错误是由于某些依赖项与系统不兼容所致。
通过运行以下命令，我设法在OSX 10.5.6（Leopard）上安装了Jekyll 3.8.5：
sudo gem install ffi -v 1.7.0
sudo gem install eventmachine -v 1.0.9.1
sudo gem install jekyll -v 3.8.5
现在尝试10.4.8 ..
