我正在尝试安装Facebook 的 fasttext Python 绑定在 Mac OSX 10.12 Sierra 上使用 pip。运行时出现以下错误sudo pip install fasttext：

----------------------------------------
为了检查包，我运行sudo pip install fasttext --no-clean以保留临时包目录。我查看它并发现实际上没有fasttext/fasttext.c文件，尽管有fasttext/fasttext.cpp文件。如果我手动运行构建命令并将fasttext.c其替换为fasttext.cpp，它似乎成功完成。
/usr/bin/clang <...> -c fasttext/fasttext.cpp <...>
但是现在，要实际安装包，我想告诉setup.py使用fasttext.cpp而不是fasttext.c。这是我不知道该怎么做的事情。Grep在文件夹中找不到任何明确提及fasttext.c，因此我认为它是被某些我不知道的规则隐式地采用的。以下是完整的setup.py文件内容：
from setuptools import setup, find_packages
from setuptools.extension import Extension
from Cython.Build import cythonize
from sys import platform
import unittest
# Define the C++ extension
if platform == "darwin":
extra_compile_args = ['-O3', '-pthread', '-funroll-loops', '-std=c++0x', '-stdlib=libc++', '-mmacosx-version-min=10.7']

extra_compile_args = ['-O3', '-pthread', '-funroll-loops', '-std=c++0x']

那么你能帮我安装这个软件包吗？
答案1
哇，令人惊讶的是，经过几个小时的挖掘，从版本 0.6.14 到 0.7.3 的简单更新distutils解决了这个问题：
sudo pip install -U distribute
不管怎样，这个想法是在我跑步后产生的
DISTUTILS_DEBUG=1 python setup.py build
准确了解构建过程中发生的情况，然后决定更新所有涉及的库。
