Pyqt5已安装，但是在导入时dll无法加载错误？

Question

So, I tried to install PyQt5(version 5.7.1) for my miniconda3(python version 3.5.1) with pip install PyQt5 and it shows up when I try conda list in console:

But no pyqt5 program is running and when I import something like:

from PyQt5.QtWidgets import QApplication

its gives an ImportError :

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: DLL load failed: The specified module could not be found.

How can I fix this? Do I have to install C++ and Qt lib for C++ for this to work?? Please Help!

Answer 1

I know it's an old question, i've found solution that worked for me, maybe it will be useful for somebody else.

conda list

should contain pyqt PyQt5 and qt . If any of it are not there, you need to install it - run:

conda install qt , for example.

I see in the question there is pyqt and PyQt5 installed, but is there qt?
