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

Question

我正在一步一步地了解Ember Guides所说的关于本地配置项目的内容。

我可以安装每个包管理器(Homebrew，Bundler)和构建器(中间人)。

但是在执行项目(bundle exec )时，我得到一个错误，服务器无法启动：

MacBook-Pro-de-Pedro:guides pedro$ bundle exec middleman
bundler: failed to load command: middleman (/usr/local/bin/middleman)
LoadError: Could not open library 'c': dlopen(c, 5): image not found.

有谁有同样的问题吗？

Answer 1

解决了！正如Yevgeniy Anfilofyev在评论中所说，有一个完整的讨论here。

在这个问题之后，我最终做的就是替换library.rb file content from the elcapt branch in the ffi/ffi project。

这可能不是解决它的最优雅的方法，但它为我做到了。

其他开发人员做了Yevgeniy在他的评论中提到的事情，这已经足够了。只需替换该文件中变量的值:将LIBC = FFI::Platform::LIBC字符串替换为LIBC = '/usr/lib/libc.dylib‘。
