'bundle exec middleman'命令在Mac OS Sierra上失败

我正在按照步骤说明Ember Guides关于本地配置项目的说明。'bundle exec middleman'命令在Mac OS Sierra上失败

我开始安装每个软件包管理器（Homebrew，Bundler）和builder（Middleman）。

但执行项目（捆绑EXEC中间人）的时候，我得到一个错误，服务器无法启动：

MacBook-Pro-de-Pedro:guides pedro$ bundle exec middleman

任何有同样的问题？

尝试在已安装的文件中编辑'lib/ffi/library.rb'。用'LIBC ='/ usr/lib/libc.dylib''替换'LIBC = FFI :: Platform :: LIBC'字符串。有充分的讨论：https：//github.com/ffi/ffi/issues/461 –

非常感谢！它向我显示了路。只是更换这条线没有为我做。我陷入了另一个错误（找不到libcurl.dylib）。所以我遵循了那条说要下载'elcapt'分支的建议。我从那里得到了library.rb文件，并在我的本地Ruby安装中替换了它。可能不是最优雅的方式来解决它，但它为我做了:)。再次感谢 – ElPiter

解决！正如Yevgeniy Anfilofyev在评论中所说，有充分的讨论here。

之后，我最终做的是取代library.rb file content from the elcapt branch in the ffi/ffi project。

这可能不是最优雅的方法来解决它，但它为我做了。

其他开发者做了什么Yevgeniy在他的评论中提到，这就够了。只需替换该文件中的变量值：将LIBC = FFI :: Platform :: LIBC字符串替换为LIBC ='/usr/lib/libc.dylib'。
