QWidget: Must construct a QApplication before a QWidget #247

Same problem. The software seems broken.

zhaozhibiao commented 1 year ago

My problem was solved in specifying pyqt5 version. I found that when installing pix2tex with pip, pyqt5 5.15 or later is installed by default, but this conflicts with components such as pyqt5-tools. This does not seem to be a problem with Latex-ocr, because I found that qt5 software such as Spyder cannot run also, and the same error is reported. So I tried to use "pip check" to view package conflicts, manually specify the version of pyqt5 (pip intall pyqt5==5.12.3), and solved this problem.

Hello @zhaozhibiao,

thank you for sharing your solution to install pyqt5 with specifying the version. Somehow it did not work for me. I had a similar issue with pyqt version 5.15.7 installed and the same error message appeared.

Do you have any other suggestions or solutions that may help resolve this issue?

Thank you for your assistance.
