树莓派 4 上的 PyQt5

Question

I'm trying to install PyQt5 on my Raspberry Pi 4. I work in a virtual env with Python 3.7 installed using source env/bin/activate I've updated my pip version to 20.2.4. If I use the command: pip install pyqt5 , the installation takes too long, it continues displaying for hours:

collecting pyqt5 Using cached PyQt5-5.15.1.tar.gz (3.3 MB) installing build dependencies ... done Getting requirements to build wheel ... done Preparing wheel metadata .../

I've tried to write sudo apt-get install pyqt5 but I found out that the package is installed for Python 2.7 version which was installed as default version on my Raspberry.

How can I install PyQt5 correctly? I want to use it in Python3.7. I previosly installed pyqtgraph with the command pip and I did not get errors.

Answer 1

You can use this command sudo apt-get install python3-pyqt5 . There is only one question that the pyqt5 by that command doesn't work in the venv of PyCharm.

Fine I found that if the selected python interpreter is system interpreter, it also worked in PyCharm.
