pycharm、pyqt5、pyinstaller打包运行后出现错误ImportError: unable to find Qt5Core.dll on PATH的解决

在 PyQt5.13 中,其 __init__.py 文件内容如下:

从上面可以看到,错误是在 raise ImportError("unable to find Qt5Core.dll on PATH") 这里报出来。这段代码的大致意思就是在系统的环境变量 PATH 路径下去找 Qt5Core.dll 文件,而实际上这个文件并不在 PATH 路径下。

我们在使用 PyInstaller 打包时,指定 -F 选项理论上是会将 Qt5Core.dll 文件打包进可执行文件的,但是由于 PyQT5.13 默认在系统 PATH 路径下查找,因此出错了。

我们可以将下面的内容注释掉,然后一切运行正常。

else:
raise ImportError("unable to find Qt5Core.dll on PATH")
