gem install memcached在Lion上失败

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

我已经安装了memcached和libmemcached homebrew。

$ 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 ([email protected]) [https://rvm.beginrescueend.com/]

但我不能安装memcached gem（1.3.5）。我粘贴安装日志。 https://gist.github.com/1395459

在make libmemcached中发生了一些错误。我看到了那些目录。

$ 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（全部）失败。

请告诉我如何安装memcached的宝石狮子：/

后记-1

我试过 “酿造环节的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

我试图移除的/ usr /本地/地窖/分布式缓存/。然后运行'brew link memcached'，但出现以下错误。

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

做到这一点：

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

您需要删除旧的链接第一：

sudo rm /usr/local/include/memcached

然后尝试brew link memcached再次

谢谢你的亲切。但我无法解决。添加Postscript-2。 – inohiro

是“sudo rm/usr/local/include/memcaced（< - 它的符号链接”正确吗？或者是“sudo rm/usr/local/Cellar/memcaced /（< - 它的目录”？ – inohiro

对不起，这是一个错字。试试这个：'sudo rm/usr/local/include/memcached' – Tilo

我觉得问题是gcc无法找到brew安装的memcached库。

尝试运行brew link memcached，然后再运行gem install memcached。
