Question

好的，我开发了一个PySide桌面应用程序，我想使用 cx_Freeze 进行共享。我在打包 paramiko 库时遇到了一些问题，但我使用此workaround解决了。

一切都在我的计算机上运行，这意味着双击cx_Freeze生成的.exe应用程序正在启动并正常工作。

当我在朋友的PC上测试该包装时，感到非常失望。

该应用无法启动并显示此错误：

  File "C:\Users\frpegora\AppData\Local\Programs\Python\Python37\lib\site-packages\cx_Freeze\initscripts\Console.py", line 26, in run

ImportError: DLL load failed: The specified module could not be found.

我认为已经解决的问题又回来了！

更确切地说，我在setup.py中为 cx_Freeze 使用了以下解决方法，通过了 paramiko 所需的DLL：

PYTHON_INSTALL_DIR = os.path.dirname(os.path.dirname(os.__file__))

build_exe_options = {"packages": ['cffi', 'cryptography'],
                     'include_files': [ os.path.join(PYTHON_INSTALL_DIR, "DLLs", "libcrypto-1_1-x64.dll"),
                     os.path.join(PYTHON_INSTALL_DIR, "DLLs", "libssl-1_1-x64.dll")]}

问题是，正如我从朋友的PC上发布的错误所示，该程序正在我的PC路径上寻找那些DLL！

您可以提出其他解决方案吗？我尝试了包括的所有东西：

手动传递DLL
复制错误中显示的整个文件夹

这是我的setup.py：

from cx_Freeze import setup, Executable 
import os.path

PYTHON_INSTALL_DIR = os.path.dirname(os.path.dirname(os.__file__))

build_exe_options = {"packages": ['cffi', 'cryptography'], 'include_files': [ ('libssl-1_1-x64.dll', os.path.join('lib', 'libssl-1_1-x64.dll')),
 ('libcrypto-1_1-x64.dll', os.path.join('lib', 'libcrypto-1_1-x64.dll'))]}


target = Executable(
    script="main_window.py",
    base = "Win32GUI",
    icon="images\\icon.ico"
    )

setup(name = "AppGen" , 
    version = "0.1" , 
    description = "" ,
    options={'build_exe': build_exe_options},
    executables = [target])

Answer 1

在GitHub repository of cryptography上查找，导致错误的行似乎是：

__import__("_ssl")

因此，您朋友的PC上可能缺少_ssl。尝试添加

import _ssl

对您的主脚本或修改设置脚本中的build_exe_options，如下所示：

build_exe_options = {"packages": ['cffi', 'cryptography'],
                     'include_files': [os.path.join(PYTHON_INSTALL_DIR, "DLLs", "libcrypto-1_1-x64.dll"),
                                       os.path.join(PYTHON_INSTALL_DIR, "DLLs", "libssl-1_1-x64.dll")],
                     'includes': ['_ssl']}

关于您的声明：

问题是，正如我从朋友电脑上发布的错误所示，该程序正在我的电脑路径上寻找那些dll！

您可能会对回溯中显示的路径产生误解：这些是附加到代码对象的文件名，它们在冻结的应用程序移动时可能无法实现。有关更多详细信息，请参见我对How to fix numpy dependencies path on a python 3.7.3 script on Linux frozen with cx_Freeze 6.0b1?的回答，以及一个cx_Freeze选项，该选项允许在冻结时实现路径。

cx_Freeze软件包无法在另一台计算机上运行
