我知道在 1 中，已经提出了一些解决方案。 /Q/47739191/13349539“> 2 和 3 。我尝试了几乎所有。我尝试过：

使用文件 4
解开和安装不同版本的Pyqt5和Pyqt5-Tools href =“ https://stackoverflow.com/a/51422398/13349539”> 5 ， 6 6
还尝试将python3.dll从python文件夹复制到虚拟环境中的脚本文件夹 7 https://stackoverflow.com/a/47143737/13349539"> 8

这些似乎都没有用，所以我试图运行pyqt5，我已经有一个.UI文件，我想运行它，我想运行它，但这一直给我带来错误。我的计算机是Windows 10

File ".\test.py", line 1, in <module> from PyQt5 import QtWidgets, uic
ImportError: DLL load failed: The specified module could not be found.

这是test.py文件：

from PyQt5 import QtWidgets, uic
import sys

app = QtWidgets.QApplication([])

win = uic.loadUi("User_Interface.ui") #specify the location of your .ui file 

win.show()

sys.exit(app.exec())

我在具有命令python test.py

已安装的软件包如下（使用pip list命令）：

click         6.7
packaging     21.3
pip           20.1.1
ply           3.11
pyparsing     3.0.9
PyQt5         5.9
pyqt5-tools   5.9.2.1.3
python-dotenv 0.20.0
setuptools    47.1.0
sip           4.19.8
toml          0.10.2

此解决方案 9 建议将C ++运行时环境升级到2015-2019，但我已经有了。

如果需要更多信息，我会很乐意为它们提供。任何帮助都非常感谢。

如果PYQT5在计算机上正常工作，您可以说明已安装的软件包和版本，以便我可以重新创建您的虚拟环境

原文

I am aware that some solutions for this have been suggested in 1, 2, and 3. I tried almost all of them.
I tried:

Running the pyuic5 using absolute paths for the file 4
Uninstalling and installing different versions of pyqt5 and pyqt5-tools 5, 6
I also tried copying the python3.dll from the python folder to the Scripts folder in the virtual environment 7, 8

None of these seemed to work, so I am trying to run PyQt5, I already have a .UI file and I would like to run it, but it keeps giving me the error. My machine is Windows 10

File ".\test.py", line 1, in <module> from PyQt5 import QtWidgets, uic
ImportError: DLL load failed: The specified module could not be found.

This is the test.py file:

from PyQt5 import QtWidgets, uic
import sys

app = QtWidgets.QApplication([])

win = uic.loadUi("User_Interface.ui") #specify the location of your .ui file 

win.show()

sys.exit(app.exec())

I execute it in a virtual environment that has Python 3.7.9 (this is what appears when i type python -V) with the command python test.py

The installed packages are the following (using the pip list command):

click         6.7
packaging     21.3
pip           20.1.1
ply           3.11
pyparsing     3.0.9
PyQt5         5.9
pyqt5-tools   5.9.2.1.3
python-dotenv 0.20.0
setuptools    47.1.0
sip           4.19.8
toml          0.10.2

This solution 9 suggests upgrading the C++ runtime environment to 2015-2019, but I already have that.
