赛通和Hadoopy 编译错误..有修复的想法吗？

Question

我正在尝试运行 Hadoopy，但在 OS X 上遇到编译错误：

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

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

完整输出：

Answer 1

对我来说，这是一个安装问题，我已经使用下面提到的步骤修复了它：

• pip install argparse

• git clone https://github.com/bwhite/hadoopy.git

• cd hadoopy

• python setup.py install

Answer 2

不使用 pyximport，而是使用 python setup.py build_ext --inplace 构建扩展模块（或者使用 python setup.pydevelop 安装进行就地开发，或者只是通过 python setup.py install 进行常规安装）。对于软件包，您几乎总是希望运行安装程序，它将正确配置编译环境、构建和安装过程。

如果您使用 Cython 来加速代码（例如科学计算），则 pyximport 对于您的个人脚本很有用。即使这样，您可能也需要引入其他库，并从多个源进行构建。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 就这么简单：

import pyximport
pyximport.install()
import foo

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