使用PyInstaller打包后PySide2应用程序中出现路径错误

Question

我正在尝试用以下结构打包PySide2测试应用程序：

.
├── main.py
├── main.spec
└── wizardUI
    ├── 10.toolBoxBtns.ui
    ├── 11.toolBoxShrCt.ui
    ├── 12.propertyBox.ui
    ├── 13.printing.ui
    ├── 14.settings.ui
    ├── 15.coclusion.ui
    ├── 1.welcomePage.ui
    ├── 2.graphicsScene.ui
    ├── 3.graphicsSceneText.ui
    ├── 4.textDialog.ui
    ├── 5.codeDialog.ui
    ├── 6.graphicsSceneBox.ui
    ├── 7.graphicsScenePixmap.ui
    ├── 8.graphicsSceneShrCt.ui
    ├── 9.toolbox.ui
    └── wizard.py

当我尝试运行可执行文件时，会出现以下错误：

FileNotFoundError: No such file or directory:'/home/artem/Desktop/testUI/dist/main/wizardUI'

这是我的wizard.py文件

from PySide2 import QtCore, QtWidgets
from PySide2.QtUiTools import QUiLoader
import os


class tutorWizard(QtWidgets.QWizard):
    """ Contains introduction tutorial """
    def __init__(self, parent=None):
        super(tutorWizard, self).__init__(parent)


        self.setWindowTitle("Introduction tutorial")
        pages = self.findPages()
        self.initPages(pages)

    def findPages(self):
        ui_files = []
        cnt = 1
        current_dir = os.path.dirname(os.path.realpath(__file__))
        while len(ui_files) != 15:
            for file in os.listdir(current_dir):
                if file.startswith("{}.".format(cnt)):
                    ui_files.append(os.path.join(current_dir, file))
                    cnt += 1
        return ui_files

    def initPages(self, files):
        loader = QUiLoader()
        for i in files:
            file = QtCore.QFile(str(i))
            file.open(QtCore.QFile.ReadOnly)

            file.reset()
            page = loader.load(file)

            file.close()

            self.addPage(page)

main.py是：

from PySide2.QtWidgets import QApplication
from wizardUI.wizard import tutorWizard
import sys


app = QApplication(sys.argv)
window = tutorWizard()
window.show()
sys.exit(app.exec_())

和.spec文件是：

# -*- mode: python ; coding: utf-8 -*-

block_cipher = None


a = Analysis(['main.py'],
             pathex=['/home/artem/Desktop/testUI'],
             binaries=[],
             datas=[],
             hiddenimports=['PySide2.QtXml'],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='main',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               upx_exclude=[],
               name='main')

a.datas += Tree('/home/artem/Desktop/testUI/wizardUI')

如果不在wizard.py中更改current_dir变量，是否有办法解决此错误

Answer 1

这是一个路径问题

简单地说,

我们应该使用此条件来获取ui文件的路径：

    if getattr(sys, 'frozen', False):
        ui_file_path = os.path.join(sys._MEIPASS, ui_file)
    else:
        ui_file_path = os.path.join(sys.path[0], ui_file)
