我想在 Mac OS X Lion (10.7.2) 上使用 memcached gem (http://fauna.github.com/fauna/memcached/)。Xcode 4.2 已经安装。

我已经安装了 Memcached 和 Homebrew 的 libmemcached。

$ brew list -v 
libmemcached 0.50
memcached 1.4.10

我使用 ruby​​ 1.9.3-p0 和 rvm（ruby 版本管理器）。

$ ruby -v 
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]
$ rvm -v
rvm 1.9.2 by Wayne E. Seguin (wayneeseguin@gmail.com) [https://rvm.beginrescueend.com/]

但我无法安装 memcached gem (1.3.5)。我在 gits 之后粘贴了安装日志。 https://gist.github.com/1395459

在构建 libmemcached 时发生了一些错误。我看到了那个目录。

$ pwd 
/Users/inohiro/.rvm/gems/ruby-1.9.3-p0/gems/memcached-1.3.5/ext/libmemcached-0.32

配置成功。但是 make (all) 失败了。

请告诉我如何将 memcached gem 安装到 Lion：/

后记-1

我试过“brew link memcached”。但是返回一个错误。我该怎么办？

$ brew link memcached 
Linking /usr/local/Cellar/memcached/1.4.10... 
Error: Cannot link memcached
Another version is already linked: /usr/local/Cellar/memcached/1.4.10

后记-2

我尝试删除 /usr/local/Cellar/memcached/。并运行“brew link memcached”，但出现以下错误。

$ rm -rf memcached
$ brew link memcached 
Error: No such keg: /usr/local/Cellar/memcached

我认为问题是 gcc 找不到 brew 安装的 memcached 库。

尝试运行brew link memcached，然后gem install memcached再次运行。

做这个：

ls -l /usr/local/include/memcached
lrwxr-xr-x  1 root  staff  43 Jul 18 14:17 /usr/local/include/memcached -> ../Cellar/memcached/1.4.5/include/memcached

您需要先删除该旧链接：

sudo rm /usr/local/include/memcached

然后再试brew link memcached一次
