Question

我正在尝试使用cx_freeze为Windows正确构建Python。我选择此工具的原因是另一个类似py2win的工具具有最新的python版本问题（当前为3.7）。

但是当我编译应用程序时，我无法启动它。我遇到错误：

from bcrypt import _bcrypt ModuleNotFoundError: No module named '_cffi_backend'

我在github和stackoverflow上寻求帮助。我所做的是使用pip重新安装密码，paramiko和cffi软件包，如此处所述：No module named _cffi_backend。也许它对我不起作用，因为我使用的是Python 3而不是2。

我的setup.py如下所示：

from cx_Freeze import setup, Executable
import os

os.environ['TCL_LIBRARY'] = r'C:\Users\Kamil\AppData\Local\Programs\Python\Python37-32\tcl\tcl8.6'
os.environ['TK_LIBRARY'] = r'C:\Users\Kamil\AppData\Local\Programs\Python\Python37-32\tcl\tk8.6'

includes = ["paramiko"]

options =   {
            "includes": includes,
            }

setup(name = 'SIMail',
      version = "0.1",
      description = "SIMail nadzor routerow" ,
      options = {"SIMailGUI.exe" : options},
      executables = [Executable("SIMailGUI.py")])

执行python setup.py构建后，我得到了很长的输出并带有一些警告：

我可以在我的setup.py中添加任何内容吗？你知道如何处理这个问题吗？我根本无法运行我的应用。

Answer 1

我有同样的错误。将“ _cffi_backend.cp36-win32.pyd”（或体系结构上的任何内容）从站点程序包复制到目标文件夹中对我来说很成功。也许是cx_freeze错误。

Answer 2

build_options = {"includes": ["_cffi_backend"]}

打开cx_Freeze编译的Python应用程序时出现错误“没有名为'_cffi_backend'的模块”
