from PyQt5.QtChart import QChart, QChartView
I get this error:
«ModuleNotFoundError: No module named 'PyQt5.QtChart'»
According to the answer, Cannot import PyQtChart in Python 3.7 fulfilled recommendations:
python -m pip install PyQt5==5.14 PyQtChart==5.14
and:
C:\P>pip3 search PyQt5
PyQt5-sip (12.7.2) - The sip module support for PyQt5
INSTALLED: 12.7.2 (latest)
PyQt5 (5.14.2) - Python bindings for the Qt cross platform application toolkit
INSTALLED: 5.14.0
LATEST: 5.14.2
C:\P>pip3 search PyQtChart
PyQtChart (5.14.0) - Python bindings for the Qt Charts library
INSTALLED: 5.14.0 (latest)
QCharted (1.1.1) - Plotting large data series using PyQtChart.
The versions are the same 5.14.0 (PyQt5) and 5.14.0 (PyQtChart), but there is the error of «ModuleNotFoundError: No module named 'PyQt5.QtChart'»
So, I was wondering what the problem is?
If I were you my friend, I would try to find a separate file with an extension of .whl and install it via CMD... It could handle your problem. Just google for a pyqt.whl wheel file extension and then learn how to install it within CMD.

While trying to run a barebones Python script that imports Pyomo 5.4.3,
from pyomo.environ import *
or
from pyomo.core import *
I get the error
ImportError: pyutilib.enum has been removed.
Python 3 now has an enum implementation in the standard library (also
available for older Python versions as the third-party enum34 PyPI
package) that supersedes this library.
When installing pyomo in a newly created Conda environment using
conda install -c conda-forge pyomo

Is there a way to solve this problem and get Pyomo working in my Python 3 environment? I am running this on Mac OS X 12 Monterey. Thanks!
This error is also happening on Python 2.7 and Pyomo 5.4.3!

I've installed xlsxwriter via terminal, with every method outlined in the docs, sudo, easy install etc, uninstalling between.
I have run the demo script successfuly with CMD + I in atom, with the demo xlsx file being placed with the text in the cell - no problems there.
As soon as I run this in IDLE however, I get the traceback:
ModuleNotFoundError: No module named 'xlsxwriter'
The module is in the frameworks directory - I'm just baffled as to why IDLE wouldn't be recognising the module when atom does?
I've searched high and low for similar issues but cannot seem to locate a workaround - this is the first itme i've run into this kind of problem with python modules.
Any help would be appreciated!
Edit:
the module is listed in my pip and pip3 list:
pip3 list
Package Version
imageio 2.6.1
numpy 1.17.4
Pillow 7.0.0
pip 19.0.3

rawpy 0.13.1
setuptools 40.8.0
tqdm 4.38.0
Wand 0.5.8
XlsxWriter 1.2.8
xlwt 1.3.0
Is there any reason why the IDLE shell would not recognise an installed module?

Appreciate your support
Managed to sort it out, the issue was related to the used SIP version.
I used SIP version compatible with PyQt5 5.7 which is SIP 4.18.1 and the problem was solved.
Next step:
$make
I faced another issue:
error: 'WindowOkButtonHint' : is not a member of 'Qt'
error: 'WindowCancelButtonHint' : is not a member of 'Qt'
To solve this I edited the ~/QtCore/sipQtCoreQt.cpp file and removed the 2 problematic lines.
http://patchwork.ozlabs.org/patch/720187/
I followed the advice from #armyoung above, and it worked out. :)
The exact way to modify configure_ng.py is to find and delete (or comment out) these two lines:
argv.append('-B')
argv.append('Qt_5_0_0')
same problem!
first:
sudo python configure_ng.py --verbose
--verbose args to see more details
then it shows:
for sip -B not support
so i modify configure_ng.py

I assume the problem is something to do with the python version changing but don't know how to fix it.

I figured it out - 'sudo python' execs the command directly so was using python2 despite being run in a virtual environment. (As per this answer). Eric now installs without errors. (But doesn't run, a different issue)
I have been trying to install SIP and PyQt4 + SIP for a while now under windows 10 in a Virtual env (legacy project so was done in PyQt4). I started in PyCharm using the package manager. I also tried command line.
C:\Users\jspada>pip install SIP
Collecting SIP
Could not find a version that satisfies the requirement SIP (from versions: )
No matching distribution found for SIP
C:\Users\jspada>pip install PyQt4
Collecting PyQt4
Could not find a version that satisfies the requirement PyQt4 (from versions: )
No matching distribution found for PyQt4
Is this because there are no builds out there for SIP and PyQt4? PyQt4 maybe because it is a bit legacy but I would think SIP would work.
Well, if the project is so old I guess it's Python 2.7. SIP doesn't have binaries at PyPI for python less than 3.5 and PyQt4 doesn't provide binaries at all.
You have to download sources for SIP and PyQt4 and compile it yourself.
You can find some precompiled packages at Unofficial Windows Binaries for Python Extension Packages.
