i am using cx_freeze to build a executable of py file with pyqt5. Following is the error

I am new to software development and I am using cx_freeze to make an executable file of a hello.py python file which is using PyQt5 module. The following error occurs repeatedly. I am using python 3.6 and PyQt5 as stated.

AttributeError: module 'lxml.etrr' has no attribute 'fromstring'

Below is my hello.py file

import sys
import time
import wikipedia
import docx
import requests
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *

doc = docx.Document()

class App(QMainWindow):


    def __init__(self):
        super().__init__()

        self.left = 50
        self.top = 100
        self.width = 400
        self.height = 300
        self.initUI()

    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)
        lbl1 = QLabel(self)
        lbl1.setText("Please enter the topics you want to print articles on")
        lbl1.setGeometry(20,20,400,40)

        lbl2 = QLabel(self)
        lbl2.setText('Topics should be separeted by comma ","')
        lbl2.setGeometry(20,40,400,40)

        lbl3 = QLabel(self)
        lbl3.setText('Make sure that your pc is connected to the internet')
        lbl3.setGeometry(20,60,400,40)

        # Create textbox
        self.textbox = QLineEdit(self)
        self.textbox.move(20, 100)
        self.textbox.resize(280,40)

        # Create a button in the window
        self.button = QPushButton('Make Article', self)
        self.button.move(20,160)

        # connect button to function on_click
        self.button.clicked.connect(self.on_click)
        self.show()

        lbl4 = QLabel(self)
        lbl4.setText('Please wait')
        lbl4.setGeometry(20,135,400,40)
        lbl4.show()



    @pyqtSlot()

        cur_topic = self.textbox.text()
        topics = cur_topic.split(",")
        for ech_topic in topics:
            try:
                para = wikipedia.summary(ech_topic, sentences = 100)
            except wikipedia.exceptions.DisambiguationError as e:

Solution

reproduced the issue,in my environment.

please try my 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)])

root cause is missing the lxml package in target folder. you need specify the packages in build options below.

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.
}
