Cython和Hadoopy編譯錯誤..修復的任何想法？

Question

我正在嘗試運行Hadoopy ，但在OS X上遇到編譯錯誤：

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

我的$PATH有/Developer/usr/bin ，我在OS X Lion 10.7上運行最新版本的XCode。 Cython是通過easy_install安裝的。

全輸出：

Answer 1

對我來說這是一個安裝問題，我已經使用下面提到的步驟修復了它：

• pip install argparse

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

• cd hadoopy

• python setup.py安裝

Answer 2

而不是使用pyximport，使用python setup.py build_ext --inplace （或使用python setup.py develop進行就地開發安裝，或者通過python setup.py install進行常規安裝）來構建擴展模塊。 對於軟件包，您幾乎總是希望運行安裝程序，這將正確配置編譯環境，構建和安裝過程。

如果您使用Cython加速代碼（例如科學計算），pyximport對您的個人腳本有用。 即便如此，您可能需要引入其他庫，並從多個源構建。 在這種情況下，您可以使用pyxbld文件來設置sources和include_dirs。 例如，假設您有foo.pyx，那么您可以將構建指令放在同一目錄中的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"])

現在使用foo就像下面這樣簡單：

import pyximport
pyximport.install()
import foo

假設沒有編譯錯誤，它幾乎是透明的，但是第一次導入模塊時會出現延遲。 后續導入將在home / profile目錄的.pyxbld子目錄中查找構建的擴展。
