【问题描述】：

我使用 2 个 python 文件和 pygame 制作了一个游戏，我正在尝试使用 cx_freeze 将其转换为 .exe。

这是 2 个脚本：

移动.py：

import pygame
from Enemy import *

pygame.init()

gameDisplay = pygame.display.set_mode((800,600))

white = [255,255,255]
black = [0,0,0]

Intro()

还有 Enemy.py：

import pygame

class Enemy:

    def setup(self,x,y,dead,subclass):
        if not dead:
            self.x = x
            self.y = y
            self.count = 0
            self.reverse = False
            self.subclass = subclass


    def calc(self, playerx, playery):

        if self.count < 10 and self.reverse == False:
            self.count += 1
            self.x += 10
        elif self.count == 10:
            self.reverse = True
            self.x += -10
            self.count += -1
        if self.count > 0 and self.reverse == True:
            self.count += -1
            self.x += -10
        elif self.count == 0:
            self.reverse = False
            self.x += 10
            self.count += 1
        return [self.x,self.y,10,10]

我输入了setup.py 来编译脚本：

import cx_Freeze

cx_Freeze.setup(
    name="Go Up: The Game",
    options = "build_exe": "packages":["pygame","Enemy"],
    executables = [cx_Freeze.Executable("Move.py")]
    )

我输入了正确的 Python 控制台命令，但出现错误：

谁能告诉我我的文件有什么问题？

【问题讨论】：

找不到电影。您可能在安装包时遇到一些问题。

【参考方案1】：

您使用的是 Python 3.2：

C:\Users\Sean\Documents\Python\Object Test>c:/python32/python setup.py build
                                              ^^^^^^^^

然而pygame 包中的nmovie.py 文件具有print 的Python 2.x 语法：

print "Unable to find a working movie backend. Loading the dummy movie class..."
^^^^^^

print is a function in Python 3.x，需要用括号调用：

print("Unable to find a working movie backend. Loading the dummy movie class...")
     ^                                                                          ^

这意味着您使用的pygame 版本适用于 Python 2.x，因此与 Python 3.x 不兼容。您需要做以下两件事之一：

在 Python 2.x 中重写您的代码，然后使用 Python 2.x 可执行文件运行 setup.py。

使用 Python 3.x 版本的 pygame。你可以在他们的website 上下载它。
