问题 I have a PyQt5 application Virtual Desktop that has a built-in browser. When I use the browser, I get JS errors from the browser similar to how Chrome puts JS and HTML errors in the "Web Inspector". How do I get rid of those errors. To replicate the errors, download Virtual Desktop and install PyQt from PYPI. You'll need to run main.py , select a QStyle, and click on the Browser (next to the power button). Go to any website (google for example) and switch back to your console. You will notice
