无法在 Ruby 中要求 'memcached'

Unable to require 'memcached' in Ruby

我已经安装了 Memcached 并尝试了一些简单的示例，效果很好。现在我正在尝试创建一个服务器并使用 Memcached 功能。

我从最简单的example.rb文件开始：

require 'memcached'
  puts 'Hello'

但是，当我尝试将文件加载到其中时，出现以下错误。

/Users/matiii79/.rvm/gems/ruby-2.2.0@global/gems/memcached- 1.8.0/lib/rlibmemcached.bundle: [BUG] Segmentation fault at 0x00000000000440 ruby 2.2.0p0 (2014-12-25 revision 49005) [x86_64-darwin14]

Abort trap: 6

知道发生了什么事吗？当然，如果我删除 example.rb 文件的第一行，它会正常加载。

正如 Jesper 所建议的，我使用 Dalli memcached client 解决了这个问题。
