I Tried to Install PyQtWebEngine, Always Stuck on the Same Problem. Couldn't Fine the solution anywhere

Question

I'm new to this. Sorry for the mess.

I've been trying to install PyQtWebEngin, first On zorin os which is dualboot along with Windows10, it failed. Then I decided to install it on Linux Mint on VM inside Windows10. The error result is alway the same.

Here take a look,

poo@poo:~/Downloads$ pip3 install PyQtWebEngine

Can you guys help me out.

Thanks in advance.

Your pip seems to be trying to use a source distribution of PyQt5 for installation, but it seems that setup.py is missing from the .tar.gz on pypi, which is odd.

According to the docs installing from source is not recommended anyway

However using pip to install from the source package is not recommended

I do not know why your pip chose to download the .tar.gz in the first place. Looking at the other whl files from you log with cp36-cp36m-manylinux1_x86_64.whl, there is a PyQt5-5.14.1-5.14.0-cp35.cp36.cp37.cp38-abi3-manylinux2014_x86_64.whl on pypi that should be compatible with your system and should be the first choice of pip for downloading.

You can try to do it manually:

wget https://files.pythonhosted.org/packages/ea/9d/d609aab4111d9d74857fb73067f7de4ca38fc1f7fff87ceba092681754cf/PyQt5-5.14.1-5.14.0-cp35.cp36.cp37.cp38-abi3-manylinux2014_x86_64.whl
pip install PyQt5-5.14.1-5.14.0-cp35.cp36.cp37.cp38-abi3-manylinux2014_x86_64.whl

And then try your installation again
