Windows Pyinstaller导入错误：带有PyQt5的DLL

我只安装了一个Python版本。是3.8

where python
C:\Users\me\AppData\Local\Programs\Python\Python38\python.exe
C:\Users\me\AppData\Local\Microsoft\WindowsApps\python.exe

首先，我检查包含PyQt5的目录中的dll文件，并看到一个非常健壮的dll文件列表：

dir C:\Users\me\AppData\Local\Programs\Python\Python38\Lib\site-packages\PyQt5\Qt5\bin

pyinstaller --onefile --log-level=DEBUG --path C:\Users\me\AppData\Local\Programs\Python\Python38\Lib\site-packages\PyQt5\Qt5\bin --upx-exclude "vcruntime140.dll" --hidden-import "PyQt5" --hidden-import "QtWidgets" test.py 

下面是

test.py

的Python源代码。这只是一个基本的进口清单，直到我开始工作：

import PyQt5
import PyQt5.QtWidgets
import PyQt5.QtGui
import PyQt5.QtCore

当我运行

test.exe

时，它似乎完成了

import PyQt5

的第一行，但第二行

import PyQt5.qtwidts

给出了以下错误：

test.exe
Traceback (most recent call last):
  File "test.py", line 9, in <module>
ImportError: DLL load failed while importing QtWidgets: The specified module could not be found.
[11136] Failed to execute script test

我已经为这个问题兜圈子好几天了。有时，当我重新启动Windows时，在使用

pyinstaller

编译后，我会出现另一个错误：

ModuleNotFoundError: No module named 'PyQt5.QtWidgets'

这很奇怪，因为我可以从python

>

终端导入：

>>import PyQt5
>>import PyQt5.QtWidgets
>>

我已经在upx关闭和打开的情况下尝试了构建。
我如何成功构建此文件以导入PyQt.qtwidget
