Question

我在Mac OS Lion上遇到pylibmc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

但它适用于sudo！

$ sudo python

有什么想法吗？

Answer 1

以32位模式安装解决了这个问题。

您需要以32位模式安装libevent
```
brew install --universal libevent
```
下载libmemcached源代码（1.0.8版本适用于我）并配置32位arch的强制功能：
```
./configure --build=i386-apple-darwin11.4.2 "CFLAGS=-m32" "CXXFLAGS=-m32" "LDFLAGS=-m32"
make
sudo make install
```
其中11.4.2是内核的版本

重新安装pylibmc

sudo pip uninstall pylibmc
sudo pip install pylibmc

现在可行了
```
$ python -c 'import pylibmc'
$
```

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