我正在尝试运行Hadoopy，但在 OS X 上出现编译错误：

ImportError: Building module failed: ["CompileError: command 'llvm-gcc-4.2' failed with exit status 1\n"

我有/Developer/usr/bin，$PATH并且正在 OS X Lion 10.7 上运行最新版本的 XCode。Cython 是通过easy_install.

完整输出：

对我来说，这是一个安装问题，我已经使用以下提到的步骤修复了它：

不要使用 pyximport，而是使用python setup.py build_ext --inplace（或使用 安装以进行就地开发python setup.py develop，或只是通过 进行常规安装python setup.py install）来构建扩展模块。对于包，您几乎总是希望运行安装程序，这将正确配置编译环境、构建和安装过程。

如果您使用 Cython 来加速您的代码（例如用于科学计算），那么 pyximport 对您的个人脚本很有用。即使这样，您也可能需要引入其他库，并从多个来源构建。在这种情况下，您可以使用 pyxbld 文件来设置源和 include_dirs。例如，假设您有 foo.pyx，那么您可以将构建指令放在同一目录中的 foo.pyxbld 中。例如：

#foo.pyxbld
def make_ext(modname, pyxfilename):
    from distutils.extension import Extension
    return Extension(name = modname,
                     sources=[pyxfilename, 'bar.c'],
                     include_dirs=['/myinclude'] )
def make_setup_args():
    return dict(script_args=["--compiler=mingw32"])

现在使用 foo 很简单，如下所示：

import pyximport
pyximport.install()
import foo

假设没有编译错误，它实际上是透明的，但在您第一次导入模块时会出现延迟。.pyxbld后续导入将在您的 home/profile 目录的子目录中查找构建的扩展。
