python-poppler-qt5 installation error on mac

Question

I am trying to install the package python_poppler-qt5 , but I've got the following error:

pip install python-poppler-qt5

So it seems to be a version conflict. Could you help me figure out how to solve this issue?

Installation environment

• macOS Catalina v 10.15.4
• python v 3.7.6
• PyQt5 v 5.15.4

After having unistalled Qt6 and installed Qt5 via homebrew I got the following error:

pip install python-poppler-qt5

Answer 1

The first error is caused by using a different version with which PyQt5 was compiled, in this case Qt6 was used but PyQt5 was compiled with Qt 5.15.4.

The second error is caused because the code uploaded to pypi has a bug, in this case the solution is to use the code from the project repository and compile it directly:

pip install PyQt-builder sip
git clone https://github.com/frescobaldi/python-poppler-qt5
cd python-poppler-qt5
sip-build
sip-install
