Pip无法安装pylibmc
这是CentOS 6.5的最终版本。
我在用Python 2.7.5，并且使用了Virtualenv这个工具。
> rpm -qa '*memcache*'

libmemcache-devel-1.4.0-0.1.rc2.el6.rf.x86_64
libmemcache-1.4.0-0.1.rc2.el6.rf.x86_64
我已经安装了@development-tools这个包。

有没有人能帮帮我？

每个人似乎都需要一些不同的东西！在 Red Hat EL 6.5 上，我需要在 EPEL 的基础上安装 IUS 仓库。这个仓库在 CentOS 6.5 上也可以用。这让我能够安装 libmemcached 1.0.16。
根据 Rackspace 的指南，安装 IUS 的步骤是：
# First install EPEL
wget http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
sudo rpm -Uvh epel-release-6*.rpm
# Then install IUS for RHEL 6.5
wget http://dl.iuscommunity.org/pub/ius/stable/RedHat/6/x86_64/ius-release-1.0-13.ius.el6.noarch.rpm
sudo rpm -Uvh ius-release*.rpm
# Or for CentOS 6.5
wget http://dl.iuscommunity.org/pub/ius/stable/CentOS/6/x86_64/ius-release-1.0-13.ius.centos6.noarch.rpm
sudo rpm -Uvh ius-release*.rpm
之后，我就可以安装一个更新版的 libmemcached（注意包的名称不同）：
sudo yum install libmemcached10
sudo yum install libmemcached10-devel
然后，最新版本的 pylibmc 也顺利安装了，命令是：
pip install pylibmc

今天我在我的CentOS系统上遇到了类似的问题。通过从EPEL库安装了libmemcached-last和libmemcached-last-devel这两个软件包，解决了这个问题。

我最后从 https://launchpad.net/libmemcached/+download 下载了最新的源代码，然后执行了三个命令：./configure、make 和 make install。

对我来说，解决办法是安装pylibmc的旧版本。1.3.0版本安装失败了，所以我选择了1.2.3版本。
pip install pylibmc==1.2.3
据我了解，pip并没有很好的方式来显示可用的包，有个叫yolk的工具，但它似乎只列出了pylibmc==1.3.0。我相信还有更好的方法，但如果你用一个很大的数字来运行安装（这个数字不太可能有实际的安装选项），它会输出一些可能的选择。如果你知道更好的方法，请告诉我。
