    Complete output from command python setup.py Egg_info:

Command "python setup.py Egg_info" failed with error code 1 in /tmp/pip-build-b2zw891b/PyQt5/

Ensuite, j'ai téléchargé le dossier Zip de https://www.riverbankcomputing.com/software/pyqt/download5 et exécutez:

python3 configure.py --qmake /home/oo/Qt/5.14.0/gcc_64/bin/qmake
make
Sudo make install

Réussi

>>> import PyQt5
>>> import PyQt5.QtCore
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'PyQt5.sip'
>>> 

Alors j'ai installé

pip3 install PyQt5.sip
pip3 install sip

Réussi

mais toujours la même erreur No module named 'PyQt5.sip' pour import PyQt5.QtCore

a également essayé PyQtChart mais toujours une erreur

pip3 install PyQtChart

Capture d'écran QT ::

Mon objectif final est d'exécuter un graphique en chandeliers en utilisant pyqt5.

Sudo python3 -m pip install pyqt5 pyqtchart

Answer 1

Parfois, il est très difficile d'installer PyQt5 sur la distribution Debian ou Ubuntu Linux. J'ai pu l'installer pour python3 sur mon système exécutant Debian 10 buster (stable).
Je l'ai installé avec le gestionnaire de paquets apt.

Sudo apt-get update 
Sudo apt-get install python3-pyqt5
