“错误：无法找到vcvarsall.bat”编译Cython代码时 [英] "error: Unable to find vcvarsall.bat" when compiling Cython code

问题描述

按照建议的此处，我已经成功安装了用于Python 2.7的Microsoft Visual C ++编译器可以编译一些Cython代码，但是：

As suggested here, I have succesfully installed Microsoft Visual C++ Compiler for Python 2.7 to compile some Cython code, but:

from distutils.core import setup
from Cython.Build import cythonize
setup(ext_modules = cythonize("module1.pyx"))

仍会产生：

错误：无法找到vcvarsall.bat

error: Unable to find vcvarsall.bat

如何使用以下命令编译Cython代码Python 2.7（例如，在Windows 7 x64上）？

注意：我已经仔细阅读了问题错误：找不到vcvarsall.bat ，但主要答案（包括修改 msvc9compiler.py ）没有解决

Note: I already carefully read the question error: Unable to find vcvarsall.bat but the main answers (including modifying msvc9compiler.py) didn't solve it.

推荐答案

我花了几个小时在此上，并且在错误：无法找到vcvarsall.bat ，这就是为什么我在此处将其与 answer your自己的问题功能：

I spent hours on this, and the information was not easily findable in error: Unable to find vcvarsall.bat, that's why I post it here with the "answer your own question" feature:

• 步骤1：安装用于Python 2.7的Microsoft Visual C ++编译器

备注：您不需要，无需修改许多论坛帖子中经常建议的 msvc9compiler.py

Remark: You don't need to modify msvc9compiler.py as often suggested in many forum posts

步骤2：只需添加 import setuptools 即可帮助Python和 Python 2.7的Microsoft Visual C ++编译器协同工作。

Step 2: Just add import setuptools that will help Python and "Microsoft Visual C++ Compiler for Python 2.7" work together.

import setuptools  # important
from distutils.core import setup
from Cython.Build import cythonize
setup(ext_modules=cythonize("module1.pyx", build_dir="build"),
                                           script_args=['build'], 
                                           options={'build':{'build_lib':'.'}})

注意： script_args 参数允许仅使用 python setup.py （例如，您最喜欢的编辑器（如Sublime Text）中的CTRL + B）运行setup.py 不必像这样传递命令行参数 ： python setup.py build 。

Note: the script_args parameter allows to run this setup.py with just python setup.py (i.e. CTRL+B in your favorite editor like Sublime Text) instead of having to pass command-line arguments like this: python setup.py build.

它有效！
