由 py2exe 和 pyinstaller 生成的 exe 不起作用 [英] exe generated by py2exe and pyinstaller not working

问题描述

我用python写了一个截图程序，想把它编译成.exe文件.所以我尝试了 py2exe 和 pyinstaller.

I wrote a screenshot program using python and wanted to compile it as .exe file. So I tried with both py2exe and pyinstaller.

我的 python 版本是 2.7.14，32 位.我使用 Windows 10.我也在这个项目中使用虚拟环境.

My python version is 2.7.14, 32bit. I use Windows 10. I also use virtual environment in this project.

我的截图程序代码如下.我通过 python screenshot.py 运行它，它截取我的屏幕截图并将其存储在保存目录中.

My code for the screenshot program is like below. I run it by python screenshot.py and it take a screenshot of my screen and stored it inside the save directory.

from PIL import Image
import pyscreenshot as ImageGrab
import time


time.sleep(3)


save_dir = "C:/Users/ling/Downloads/test/"

def grab():
    im = ImageGrab.grab()
    im.save(save_dir + "screenshot.png")


if __name__ == "__main__":
    grab()

pyinstaller

对于pyinstaller，我只需使用pip install pyinstaller 安装它.安装的版本 -> 3.3.1.请注意，我在虚拟环境中安装了这个包.

pyinstaller

for pyinstaller, I simply install it using pip install pyinstaller. The version that was installed -> 3.3.1. Note that I install this package inside virtual environment.

我通过运行 pyinstaller --onefile screenshot.py 来编译程序.它生成了一个可执行的screenshot.exe.当我运行可执行文件时，没有截图.

I compiled the program by running pyinstaller --onefile screenshot.py. It generated an executable screenshot.exe. When I run the executable, no screenshot was taken.

对于安装 py2exe，由于在运行 python 2 的 Windows 计算机上安装它存在一些问题，我遵循了这个 link

For installing py2exe, since there is some issue regarding installing it on Windows computer running python 2, I followed the tutorial from this link

我创建了 setup.py 以将 screenshot.py 编译为 screenshot.exe.下面是 setup.py

I create setup.py to compiled screenshot.py as screenshot.exe. Below is the code for setup.py

from distutils.core import setup
import py2exe

setup(
      console=[{'script':'screenshot.py'}],
      options = {
            'py2exe': {
                'includes': ['PIL','pyscreenshot','time'],
                'bundle_files': 1, 'compressed': True
             }
      },
      zipfile = None
)

我使用 python setup.py py2exe 运行它.它生成了一个可执行文件.当我运行此文件时，结果与 pyinstaller 相同.没有截图.

I run it by using python setup.py py2exe. It generated a single executable file. When I run this file, the result is same as pyinstaller. There is no screenshot taken.

我需要关于为什么 screenshot.exe 不起作用的帮助.我错过了什么吗?

I need help on why does the screenshot.exe not working. Am I missing something?

感谢您的帮助.

推荐答案

解决了！

以下是screenshot.py 的修改后的代码.通过 py2exe 运行它.

Below are the modified code for screenshot.py. Run it via py2exe.

from multiprocessing import Process, freeze_support
from PIL import Image
import pyscreenshot as ImageGrab
import time

time.sleep(3)


save_dir = "C:/Users/ling/Downloads/test/"

def grab():
    im = ImageGrab.grab()
    im.save(save_dir + "screenshot.png")

if __name__ == "__main__":
    freeze_support()
    p = Process(target=grab)
    p.start()

事实证明，我需要从 multiprocessing 中包含 freeze_support 和 Process

It turned out that I need to include freeze_support and Process from multiprocessing
