安装 PyQt5 时出错

Question

So I'm completely new to PyQt and I have absolutely no idea how to install, and run it. Most online sources are saying to simply write 'pip install pyqt5' in CMD, but I'm getting errors as listed in the photo link above. I run python from Anaconda so I'm using that, but I don't see any issues with why it wouldn't work. I tried to put the pyqt folder into the directory that the console was reading but the errors persist. Any ideas? Thanks!

Errors: (base) C:\Users\TMNT5>pip install pyqt5 Collecting pyqt5 Using cached PyQt5-5.14.2-5.14.2-cp35.cp36.cp37.cp38-none-win_amd64.whl (52.9 MB) Requirement already satisfied: PyQt5-sip<13,>=12.7 in c:\users\tmnt5\anaconda3\lib\site-packages (from pyqt5) (12.7.2) ERROR: spyder 4.0.1 requires pyqtwebengine<5.13; python_version >= "3", which is not installed.

Answer 1

It appears you're not using Python 3 to install PyQt5.

pip install python-qt5

Installs unofficial PyQt5 via PyPI for Python 2.7 64-bit on Windows
