Cython＆Hadoopy编译错误..有关修复的任何想法？

Question

我试图运行Hadoopy，但我在OS X上得到一个编译错误：

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

我在$PATH有/Developer/usr/bin，并正在运行的OS X Lion的10.7最新版本的Xcode。 Cython通过easy_install安装。

全输出：

Answer 1

而不是使用pyximport的，与python setup.py build_ext --inplace建立扩展模块到位（或python setup.py develop安装就地开发，或只是一个普通的通过python setup.py install安装）。对于软件包，您几乎总是希望运行安装程序，这将正确配置编译环境，编译和安装过程。如果你使用用Cython加快你的代码（例如，用于科学计算）

pyximport好您的个人脚本。即使那样，您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sources和include_dirs。例如，假设您有foo.pyx，那么您可以将构建指令放置在同一目录中的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是作为下面简单：

import pyximport 
pyximport.install() 
import foo 

。假定有没有编译错误，它几乎透明的，但延迟的第一次导入模块。后续导入将在家庭/个人资料目录的.pyxbld子目录中查找构建的扩展。

对我来说这是一个安装问题，使用下述步骤，我已经固定它的某个时候回来：

• PIP安装argparse

• 混帐克隆https://github.com/bwhite/hadoopy.git

• CD hadoopy

• python setup.py install
