PyQt5：QtCore.abi3.so：未定义符号：_ZdaPvm，Python3.8 Ubuntu22 上的版本 Qt

问：

我正在尝试使用包执行程序，但有一个.为了直观起见，我写了一个简单的.qtpyImportErrortest.py

test.py

from PyQt5.QtCore import PYQT_VERSION
from PyQt5.QtCore import QT_VERSION

print(PYQT_VERSION) 
print(QT_VERSION)

错误是

ImportError: /home/malloc/anaconda3/envs/paddleseg/lib/python3.8/site-packages/PyQt5/QtCore.abi3.so: undefined symbol: _ZdaPvm, version Qt_5

我不知道如何解决它，尽管我尝试了很多方法。

Python 版本为 3.8，Ubuntu22。

命令的一部分

nm /home/malloc/anaconda3/envs/paddleseg/lib/python3.8/site-packages/PyQt5/QtCore.abi3.so | grep "U "IS 的输出QtCore.abi3.so

你说你正在使用，但你的代码没有。因此，您要么遇到配置/设置问题，要么没有提供适当的示例代码作为参考。模块只是其他模块周围的填充码，最重要的是，该模块基于永远无法协同工作的 Python 绑定。由于内部错误，该错误可能是由该模块单独引起的，但我们无法确定。尽管如此，根据你的输出，你有两个完全不同的、不相关和不兼容的Qt版本，因为你的PyQt是基于Qt5的，而你的PySide是基于Qt6的。qtpyqtpy

我从未使用过 anaconda，所以我不能在这里真正帮助你，但有可能：你的设置有一些可能导致问题的“剩余物”（例如，你删除了 PySide6，但你同时拥有 shiboken 2 和 6）。另外，如前所述，你说你正在使用 qtpy，但你的代码没有，所以要么你实际上没有使用 qtpy，要么你没有提供有效的最小可重现示例。它还有助于获得有关您的配置的更多详细信息，例如您的操作系统，如果您正在使用虚拟化等。

答： 暂无答案

上一个：显式模板实例化，但仍未定义引用（使用 g++，但不使用 clang++）

下一个：在 zig 中使用 opencv，错误：lld-link：未定义的符号：cv：：imread
