How to install PyQt5 on raspbian stretch with python 3.6?

[alexryan]

The only way that I was able to get PyQt5 installed and running on raspbian stretch was by installing with apt-get. But that version only appears to work with python 3.5. I need a version that works with python 3.6.

pip install failed ...

(qt) pi@qa:~ $ pip install PyQt5
Collecting PyQt5
  Could not find a version that satisfies the requirement PyQt5 (from versions: )
No matching distribution found for PyQt5

(qt) pi@qa:~ $ pip install python3-pyqt5
Collecting python3-pyqt5
  Could not find a version that satisfies the requirement python3-pyqt5 (from versions: )
No matching distribution found for python3-pyqt5

noticed that a version did seem to be available via agt-get

(qt) pi@qa:~ $ apt-cache search pyqt5
pyqt5-dev - Development files for PyQt5

I installed this ...

but it seems to have been built against python 3.5 ...

/usr/lib/python3/dist-packages/PyQt5/QtXml.cpython-35m-arm-linux-gnueabihf.so

if you try to use it with python 3.6, the import statement will fail ...

this works

>>> import PyQt5

but this gives a No Module Found error

>>> import PyQt5.QtGui

Is it possible to get PyQt5 installed on raspbian stretch for use with python 3.6?

Hi and welcome to devnet,

That's a question better asked to the PyQt authors on their mailing list.
