Question

我正在使用cx_freeze开发版本（建议here，也尝试了最新的稳定版1.3.1），我尝试从导入numpy和Enthought Canopy的文件构建Windows的可执行文件分配。这是文件test.py：

import numpy as np

def f(x):

    y = np.linspace(0,x,1000)
    return y

if __name__ == '__main__':
    print f(5)

这是setup.py文件：

import sys
from cx_Freeze import setup, Executable

# Dependencies are automatically detected, but it might need fine tuning.
build_exe_options = {"packages": ["os"], "excludes": ["tkinter"]}

# GUI applications require a different base on Windows (the default is for a
# console application).
base = None
if sys.platform == "win32":
    base = None

setup(  name = "foo",
        version = "0.1",
        description = "My GUI application!",
        options = {"build_exe": build_exe_options},
        executables = [Executable("test.py", base=base)])

这是我在运行exe时遇到的错误：

我注意到构建目录中有一个numpy.linalg.lapack_lite.pyd文件。

在Python安装目录中，转到Scripts目录（即C：/ Python27 / Scripts）。在此文件夹中，您应找到两个DLL文件：

mk2_core.dll
mk2iomp5md.dll

编辑cxFreeze构建例程，以便将这两个文件复制到与可执行文件（构建目录）相同的目录中。在那之后，尝试运行exe，这应该解决问题（无论如何它都为我做了）。

我是怎么想出来的？你说你注意到了numpy.linalg.lapack_lite.p.yd文件。我所做的是使用名为DependencyWalker（website）的工具打开此文件。该程序分析文件具有的所有DLL依赖性。经过分析，它告诉我这两个DLL文件丢失了。

我真的希望这会有所帮助，我知道这些事情是多么令人沮丧！

cx_freeze无法构建numpy可执行文件
