我正在使用cx_freeze用pyqt5构建py文件的可执行文件。 以下是错误

Question

我是软件开发的新手，我正在使用cx_freeze来制作使用PyQt5模块的hello.py python文件的可执行文件。 反复发生以下错误。 我正在使用python 3.6和PyQt5如所述。

AttributeError：模块“ lxml.etrr”没有属性“ fromstring”

下面是我的hello.py文件

Answer 1

您的hello.py是否有导入的库？

Answer 2

在setup.py中，您需要包含已使用的模块，并将其包含在构建中。

这是一个答案的链接，它比我能更好地解释它。 根据您的答案，您将需要为所有导入的模块使用路径。 最好只使用每个模块的需求，并且可能需要对每个模块的方式进行更多研究。

在我的环境中重现了该问题。

请尝试我的setup.py

import sys
from cx_Freeze import setup, Executable

# Dependencies are automatically detected, but it might need fine tuning.
build_exe_options = {
    "packages": ["idna","lxml"],
    "includes": ["urllib3","queue"],
    "excludes": ["tkinter"],
    # "include_files":[('./platforms','./platforms')] # uncomment if need qwindows.dll for qt5 application, you need put qwindows.dll in "./platforms" folder.
}

# GUI applications require a different base on Windows (the default is for a
# console application).
base = None
if sys.platform == "win32":
    base = "Win32GUI"

setup(  name = "demo",
        version = "0.1",
        description = "demo",
        options = {"build_exe": build_exe_options},
        executables = [Executable("demo.py", base=base)])

根本原因是目标文件夹中缺少lxml软件包。 您需要在下面的构建选项中指定软件包。

build_exe_options = {
    "packages": ["idna","lxml"],
    "includes": ["urllib3","queue"],
    "excludes": ["tkinter"],
    # "include_files":[('./platforms','./platforms')] # uncomment if need qwindows.dll for qt5 application, you need put qwindows.dll in "./platforms" folder.
}
