文件转换为exe不能生成条码

Question

I tried to generate barcode and made a GUI using pyqt5 when I run it through scripts it works perfectly but when I converted the.py file to.exe file when I try to generate it, it gives many tracebacks

import pkg_resources.py2_warn
from PyQt5 import QtCore, QtGui, QtWidgets
import barcode
from barcode.writer import ImageWriter
import shutil
import os


class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(607, 503)
        self.pushButton = QtWidgets.QPushButton(Form)
        self.pushButton.setGeometry(QtCore.QRect(-170, 220, 93, 28))
        self.pushButton.setObjectName("pushButton")
        self.horizontalLayoutWidget = QtWidgets.QWidget(Form)
        self.horizontalLayoutWidget.setGeometry(QtCore.QRect(130, 180, 311, 80))
        self.horizontalLayoutWidget.setObjectName("horizontalLayoutWidget")
        self.horizontalLayout = QtWidgets.QHBoxLayout(self.horizontalLayoutWidget)
        self.horizontalLayout.setContentsMargins(0, 0, 0, 0)
        self.horizontalLayout.setObjectName("horizontalLayout")
        self.lineEdit = QtWidgets.QLineEdit(self.horizontalLayoutWidget)
        self.lineEdit.setObjectName("lineEdit")
        self.horizontalLayout.addWidget(self.lineEdit)
        self.pushButton_2 = QtWidgets.QPushButton(self.horizontalLayoutWidget)
        self.pushButton_2.setObjectName("pushButton_2")
        self.horizontalLayout.addWidget(self.pushButton_2)
        self.pushButton_2.clicked.connect(lambda: self.testEan(self.lineEdit.text()))
        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self, Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setWindowTitle(_translate("Form", "Form"))
        self.pushButton.setText(_translate("Form", "PushButton"))
        self.pushButton_2.setText(_translate("Form", "Generate"))

    def testEan(self, i):
        EAN = barcode.get_barcode_class('code128')
        s = '0' * (8 - len(str(i)) - 1) + str(i)
        ean = EAN(s, writer=ImageWriter())
        fullname = ean.save(str(i))
        try:
            os.mkdir("Barcode")
        except FileExistsError:
            pass
        try:
            shutil.move(fullname, "Barcode")
        except:
            pass
        QtWidgets.QMessageBox().about(QtWidgets.QWidget(), "Info", "Success")


if __name__ == "__main__":
    import sys

    app = QtWidgets.QApplication(sys.argv)
    Form = QtWidgets.QWidget()
    ui = Ui_Form()
    ui.setupUi(Form)
    Form.show()
    sys.exit(app.exec_())

NOTE: I have imported pkg_resources.py2_warn because without it when i try to execute the application it throws no module name pkg_resources.py2_warn

Traceback: (most recent call last)
 File "Bar.py" line 37, in <lambda>

OsError : cannot open resource

OS          : windows 10
Python      : 3.8.3

Is there any way to overcome that traceback error?

Answer 1

IO Error:Cannot open image while generating barcode after freezing using py2exe

as stated here you should alter or include the font in you code, so it can read it. I chosed to alter the code to a "standard" font instead.

i posted in a similar issue on the repo as well: https://github.com/WhyNotHugo/python-barcode/issues/69
