Pyinstaller 独立可执行文件找不到规范文件中定义的 ui 文件

Posted 2023-03-30

【中文标题】Pyinstaller 独立可执行文件找不到规范文件中定义的 ui 文件

【英文标题】：Pyinstaller standalone executable cannot find ui file defined in spec file

【发布时间】：2020-05-19 09:03:43

【问题描述】：

我正在使用 pyinstaller 编译一个独立的可执行文件。 python 脚本使用来自 QtDesigner 的外部 ui 文件。如果没有 ui 文件，我无法让它运行可执行文件。我阅读了有关定义规范文件的信息，但是如果没有 ui 文件，我尝试的一切都不起作用。我不知道我做错了什么。我可以编译它，但是当我删除 ui 文件并运行可执行文件时，我得到了错误：

FileNotFoundError: [Errno 2] No such file or directory: 'D:/visu.ui'

如何将此文件集成到可执行文件中？

这是我的代码。使用pyi-makespec生成spec文件并手动添加数据：

visu.py

import sys
import os
from PyQt5 import QtWidgets, uic

def resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """
    try:
        # PyInstaller creates a temp folder and stores path in _MEIPASS
        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")

    return os.path.join(base_path, relative_path)

Ui_MainWindow, QtBaseClass = uic.loadUiType(resource_path('visu.ui'))

class MyWindow(QtWidgets.QMainWindow, Ui_MainWindow):
    def __init__(self):
        QtWidgets.QMainWindow.__init__(self)
        Ui_MainWindow.__init__(self)
        self.setupUi(self)
if __name__ == "__main__":
    app = QtWidgets.QApplication(sys.argv)
    window = MyWindow()
    window.show()
    sys.exit(app.exec_())

visu.ui

<?xml version="1.0" encoding="UTF-8"?>

visu.spec

block_cipher = None


a = Analysis(['D:/visu.py'],
             pathex=['C:\\Users\\xxx'],

             datas=[("visu.ui", '.')],
             hiddenimports=[],

             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='visu',
          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='visu')

【参考方案1】：

我确定如果您将visu.ui 文件转换为visu.py

pyuic5 visu.ui -o visu.py 

那么你不会有任何问题。

pyinstaller -F -w pyinstaller_standalone_executable.py

pyinstaller_standalone_executable.py

import sys
import os
from PyQt5 import QtWidgets     #, uic

from visu import Ui_Dialog

    try:

        base_path = sys._MEIPASS
    except Exception:
        base_path = os.path.abspath(".")

    return os.path.join(base_path, relative_path)

Ui_MainWindow, QtBaseClass = uic.loadUiType(resource_path('visu.ui'))
