cx\u冻结包在另一台机器上不起作用

Question

好的，我开发了一个PySide桌面应用程序，我想用cx\u Freeze来共享它。我在打包paramiko库时遇到了一些问题，但是我用这个workaround解决了这个问题。你知道吗

一切都在我的机器上运行，这意味着双击cx\u Freeze生成的.exe，应用程序启动并正常工作。你知道吗

当我在朋友的电脑上测试这个软件包时，我感到非常失望

应用程序未启动并显示此错误：

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

我以为已经解决的问题又回来了！你知道吗

更确切地说，前一段时间，我在setup.py中为cx\u Freeze传递了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，如我在朋友的电脑上发布的错误所示，程序正在我的电脑路径上查找那些DLL！你知道吗

你能提出不同的解决方案吗？我什么都试过了包括：

• 手动传递DLL
• 复制错误中显示的整个文件夹

这是我的设置.py地址：

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

从GitHub repository of cryptography上看，导致错误的行似乎是：

__import__("_ssl")

因此，您朋友的电脑上可能缺少_ssl。请尝试添加

import _ssl

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']}

关于你的陈述：

The problem is that as shown in the error I posted from my friend's pc, the program is looking for those dlls on my PC's path!

您可能会被回溯中显示的路径所误导：这些是附加到代码对象的文件名，当冻结的应用程序被移动时，这些文件名可能不会实现。有关更多详细信息，请参阅我对How to fix numpy dependencies path on a python 3.7.3 script on Linux frozen with cx_Freeze 6.0b1?的回答，以及允许在冻结时实现路径的cx\u冻结选项。你知道吗
