在尝试遵循http://code.google.com/p/python-libmemcached/上的 python-libmemcached 说明时，我在第 3 步遇到了麻烦（“python setup.py install”）

我几乎不知道这意味着什么或做什么。我的电脑上确实有多个版本的 gcc（4.0 和 4.2），并且从谷歌搜索中收集到了足够的信息，这可能很重要。否则完全输了。

提前致谢。

我现在收到一个完全不同但仍然令人困惑的错误：

出现该错误是因为该文件cmemcached_imp.c不存在，但必须在此步骤中编译。

首先，编辑文件cmemcached_imp.pyx并修正第 506 行的错字。

sys.stderr.write("[cmemcached]%s only support string: %s" % (cmd, key))

，应该说

sys.stderr.write("[cmemcached]%s only support string: %s" % (cmd, keys))

然后，安装cython并执行

$ cython cmemcached_imp.pyx

cython 应该默默地生成文件cmemcached_imp.c。

虽然这将修复即时错误，但您可能还需要更换

ext_modules=[Extension('cmemcached_imp',
            ['cmemcached_imp.pyx', 'split_mc.c'],

在setup.py与

ext_modules=[Extension('cmemcached_imp',
            ['cmemcached_imp.c', 'split_mc.c'],

回应编辑：

如果您逐字按照说明进行操作，您还需要在本地目录中安装 libmemcached。执行

$ ln -s $(pwd)/../libmemcached-0.40/libmemcached

在 python-libmemcached 中实现这一点。
