【问题描述】：

我试图将 python 文件转换为 .exe 文件。但是有了这两行，我就遇到了这个问题。

import cv2
exit()

AttributeError: Module 'PyQt5' has no attribute '__version__'

如果我只是打印类似：print('dsfdsfs') 的内容，那么它可以成功包装到 .exe。

我的环境：
win10
pyinstaller 5.0.dev0
opencv-python 4.5.2.54
pyqt 5.9.2

我正在使用 anaconda 提示符来执行此操作。

【问题讨论】：

我也收到了类似的错误，

标签： python-3.x pyqt5 pyinstaller

【解决方案1】：

尝试使用“pip install PyQt5”然后再次运行

【讨论】：

没用，我用的是python 3.6.7，pip install PyQt5
在我的情况下工作

【解决方案2】：

我想出了一个解决办法。当您使用 auto-py-to-exe 将 .py 文件转换为 .exe 时，您必须单击“高级”，然后在其中添加“隐藏导入”，然后将导入的内容添加到 .py 文件中，例如 my . py 文件导入“sounddevice”“numpy”和“os”，所以我将所有这些添加到 auto-py-to-exe 中的“隐藏导入”中我希望这会有所帮助 - 这是一张图片：example

【讨论】：

【解决方案3】：

我正在使用 pyinstaller 和 anaconda 提示，发现同样的问题，你必须解决它

pip install PyQt5 --user --use-feature=2020-resolver

然后再次运行 pyinstaller。

【讨论】：

它显示消息，没有这样的选项：--use-feature
@AbhilashSinghChauhan 这是 pip 的问题，尝试升级到最新版本的 pip 并重试python -m pip install --upgrade pip

【解决方案4】：

我通过手动将__version__ = "5.15.4" 添加到venv/Lib/site-packages/PyQt5/__init__.py 解决了这个问题，其中venv 是安装了PyQt5 的虚拟环境。

之前：

...

# WARRANTY OF DESIGN, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.


# Support PyQt5 sub-packages that have been created by setuptools.
__path__ = __import__('pkgutil').extend_path(__path__, __name__)

def find_qt():
...

之后：

...
# 
# This file is provided AS IS with NO WARRANTY OF ANY KIND, INCLUDING THE
# WARRANTY OF DESIGN, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.


# Support PyQt5 sub-packages that have been created by setuptools.
__path__ = __import__('pkgutil').extend_path(__path__, __name__)
__version__ = "5.15.4"

def find_qt():
...

【讨论】：

我可以确认这对我有用，但我不确定它是否是最佳解决方案。这是一种快速奏效的技巧！

【解决方案5】：

在这件事上浪费了太多时间后，我更新了 PyInstaller，瞧，它工作了。

【讨论】：

什么版本的 PyInstaller ？

【解决方案6】：

不幸的是，Anaconda 上的 PyQt5 模块似乎被破坏并丢失了其他模块可能需要的各种文件，在我的例子中是 PySimpleGui。最简单的解决方案是创建一个全新的环境，幸运的是这在 anaconda 中相当容易，并且 pip install pyqt5。这应该可以解决任何问题。还要安装其余的软件包，你应该一切顺利！

【解决方案7】：

我遇到了同样的问题。 pip install PyQt5 出错... Pyinstaller 团队需要一些认真的帮助。恢复到可在我的系统上运行的以前版本的 Pyinstaller。
