Install PyQt5 5.14.1 on Linux (3 answers)

Closed 3 months ago.

Whenever I try to install a package, for example pip3 install PyQt5 the command fails with a message about a missing directory in the /tmp directory

pip3 install PyQt5

Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-0shdy0kn/PyQt5/

When I look in the /tmp directory no pip-install-xxxxxxx directories exist and it looks like the process doesn't create them at all.

As a quick fix you can sudo apt-get install python3-pyqt5

But for the sake of your question. Does this happen with any package?

Can you try installing any of the following just to see if it works, these are just quick examples.

pip3 install numpy==1.18.1
pip3 install pandas==0.25.3
pip3 install pep8==1.7.1
pip3 install pika==1.1.0

One reason could be that PyQt5 is to be used with python 2 and hence might only work with pip install PyQt5
