Then I downloaded zip folder from https://www.riverbankcomputing.com/software/pyqt/download5 and run:
python3 configure.py --qmake /home/oo/Qt/5.14.0/gcc_64/bin/qmake
make
sudo make install
Successful
>>> import PyQt5
>>> import PyQt5.QtCore

So I installed
pip3 install PyQt5.sip
pip3 install sip
Successful
but still getting same error No module named 'PyQt5.sip' for import PyQt5.QtCore
also tried PyQtChart but still error
pip3 install PyQtChart

Answers:
It seems that there is a bug in the latest version of PyQt5 to pypi so I installed a version 5.14:
sudo apt-get update &&
sudo apt-get autoclean
sudo apt-get update && sudo apt-get install
-y --no-install-recommends
python3-pip
python3-setuptools
sudo python3 -m pip install pyqt5==5.14 pyqtchart==5.14
Copy the example of my previous answer in the main.py and then run:
python3 main.py
I recommend you search the folders and files generated by your failed attempts and delete them.
For my test I used the following Dockerfile
I think the initial pip install woes were due to PyQt5 switching to the manylinux2014 platform tag for the latest release (see the wheels on PyPI for 5.14.1 vs 5.14.0). Only pip versions >= 19.3 recognize this platform tag (ref), so if you happen to have an older version of pip, it would instead try to install from source.
Two easy options (to avoid the source install):
- Update pip to the latest via
pip3 install --upgrade pip
- Install the previous release, which used manylinux1 (
pip3 install pyqt5==5.14.0)
I also had the same issue installing PyQt5 (while trying to install ReText).
On Ubuntu 18.04 with Python 3.6.9 and Pip 9.0.1, I was able to pip install PyQt5 with these steps:
python3 -m venv env
source env/bin/activate
pip3 install pyqt5 --only-binary pyqt5
That was enough to make pip download the PyQt5-5.14.0-5.14.0-cp35.cp36.cp37.cp38-abi3-manylinux1_x86_64.whl binary wheel (that doesn’t need/use the setup.py) instead of building from the source tarball.
According to https://pypi.org/project/PyQt5/#files, there are other binary wheels too, so hopefully that’ll cover most platform needs.
Sometimes it is very difficult to install PyQt5 on Debian or Ubuntu Linux distro.
I was able to install it for python3 on my system running Debian 10 buster (stable).
I installed it with the apt package manager.
sudo apt-get update
sudo apt-get install python3-pyqt5
For those who do not desperatly need 5.14, 5.12 can be a solution. This worked for me:
sudo python3 -m pip install pyqt5==5.12 pyqtchart==5.12
As the Question showed, you are downloading tar.zip file not wheel. Installing QT with pip is only allowed with wheel. Choose the version that has wheel file in PyPI homepage and matches to your Python version.
I have this problem too. It’s because your pip is on older version and you should update it by using the below commands:
pip3 install setuptools wheel
pip3 install --upgrade pip
pip3 install --user pyqt5
I had to build right version of sip from source in order to build desired version of PyQt5 from source and then I also got following error:
No module named 'PyQt5.sip'
and then
python3 -m pip install PyQt5.sip
solved the issue
pip3 install PyQt5
