无法通过pip安装pylibmc

Question

我正在尝试在Mac上安装pylibmc。
我的Mac环境是OSX El Capitan 10.11.2。

我尝试了pip install pylibmc，但是我收到了以下错误信息。

我已经安装了以下软件：

• brew install libmemcached
• Command Line Tools
• export CFLAGS=-Qunused-arguments @shell
• export CPPFLAGS=-Qunused-arguments @shell

我该如何安装pylibmc？

似乎libmemcached未正确安装。 - Atul Jain

Answer 1

首先你需要安装

brew install libmemcached

然后通过以下命令安装Python包：

pip install pylibmc --install-option="--with-libmemcached=/usr/local/Cellar/libmemcached/1.0.18/"

非常感谢。我成功安装了pylibmc。 - naohide_a

我使用了/usr/local/Cellar/libmemcached（没有指定版本），它也可以正常工作。 - reubano

非常感谢您的回答。 - hygull

根据Homebrew的版本/设置，libmemcached可能在其他位置，请在安装后使用brew info libmemcached检查其位置，并相应更改安装选项。我的位置是/opt/homebrew/Cellar/libmemcached。 - José

Answer 2

安装开发包：

sudo apt-get install libmemcached-dev
sudo apt-get install zlib1g-dev

然后使用pip安装Python包：

pip install pylibmc

请查看要求的文档

请检查一下，@naohide。 - user5783857

我在我的CentOS服务器上使用了yum install libmemcached-devel，然后pylibmc成功安装。希望这对于遇到相同问题的其他人有所帮助。 - Alfred

Answer 3

更新@Atul的接受答案-首先您需要安装

brew install libmemcached

然后检查已安装的版本

ls /usr/local/Cellar/libmemcached (截至今天，1.0.18_2是最新版本)

现在通过在此命令中替换上述版本来安装Python包

pip install pylibmc --install-option="--with libmemcached=/usr/local/Cellar/libmemcached/<version>"

例如：

pip install pylibmc --install-option="--with libmemcached=/usr/local/Cellar/libmemcached/1.0.18_2/"

三个步骤，包括在重新启动计算机时自动启动memcached服务器

1. brew install libmemcached
2. pip install pylibmc
3. ln -s /usr/local/Cellar/memcached/1.4.24/homebrew.mxcl.memcached.plist ~/Library/LaunchAgents/ （注意：您需要将版本号修改为您自己的版本号，在这里是1.4.24）
4. launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.memcached.plist （注意：如果您不想以后自动启动memacached服务器，可以使用卸载命令）
