Mac OS Lion上的pylibmc出错

Question

我对Mac OS Lion上的pylibmc有问题。

libmemcached - 1.0.4

pylibmc - 1.2.3

$ python
Python 2.7.1 (r271:86832, Jun 25 2011, 05:09:01) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pylibmc
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Python/2.7/site-packages/pylibmc/__init__.py", line 70, in <module>
    import _pylibmc
ImportError: dlopen(/Library/Python/2.7/site-packages/_pylibmc.so, 2): Symbol not found: _memcached_add
  Referenced from: /Library/Python/2.7/site-packages/_pylibmc.so
  Expected in: flat namespace
 in /Library/Python/2.7/site-packages/_pylibmc.so

但是它可以和sudo一起工作！

$ sudo python

>>> import pylibmc
>>> 

有什么想法吗？

Answer 1

在32位模式下安装解决了这个问题。

1. 您需要在32位模式下安装libevent

brew安装--下载libmemcached源代码(1.0.8版适用于我)的通用libevent

• ，并为32位arch配置强制：

./configure --build=i386-apple-darwin11.4.2 "CFLAGS=-m32“"CXXFLAGS=-m32”"LDFLAGS=-m32“make sudo make install

其中11.4.2是kernel

• Reinstall pylibmc的版本

sudo pip卸载pylibmc sudo pip安装pylibmc

• 现在可以工作了

$ python -c 'import pylibmc‘$

看起来像是libmemcached的构建和/或安装问题。也许你可以看看101期？https://github.com/lericson/pylibmc/issues/101
