python - 无法使用 cx_Freeze 进行编译

Question

我制作了一个运行良好的程序，现在我尝试使用 cx_Freeze 编译它，但收到 TypeError: can only concatenate list (not "NoneType") to list 错误。那么我该如何解决这个问题，以便我可以将我的程序正确编译为.exe

我的配置: python 2.7，cx_Freeze 5.1.1

我的程序包含以下模块: os、time、string、random、smtplib、_winreg、requests、pyautogui、subprocess、email、SimpleCV

我的设置文件代码:

import sys
from cx_Freeze import setup, Executable


company_name = 'My own company'
product_name = 'Program'

sys.setrecursionlimit(5000)

bdist_msi_options = {
    'add_to_path': False,
    'initial_target_dir': r'[C:\Program Files (x86)]\%s\%s' % (company_name, product_name),
    }

path = sys.path
build_exe_options = {
"path": path,
"icon": "myicon.ico"}

base = None
if sys.platform == "win32":
    base = "Win32GUI"

exe = Executable(script='My_program.py',
                 base=base,
                 icon='myicon.ico',
                )

setup(name = "My program",
      version = "1.1",
      description = "This is my first program",
      executables = [exe],
      options = {'bdist_msi': bdist_msi_options})

错误:

  File "setup.py", line 33, in <module>
    options = {'bdist_msi': bdist_msi_options})
  File "C:\Python27\lib\site-packages\cx_Freeze\dist.py", line 349, in setup

解决方案是将opencv_ffmpeg342.dll文件放置在可执行文件所在的同一目录中。

opencv_ffmpeg342.dll is located at [Place where you have installed python] \ Lib \ site-packages \ cv2
