Hi fe8769a. Hmmm, sounds like it's not finding PyQtChart. Just to double-check if you do an apt search do you have python3-pyqt5 installed? does 'pip3 search PyQtChart' show a version installed? Just for good measure, what OS are you running on?

I checked on both my Ubuntu and Kali/Debian test systems and both report back like this:
'pip3 search pyqtchart'
PyQtChart (5.9.2) - Python bindings for the Qt Charts library
INSTALLED: 5.9
LATEST: 5.9.2

[fe8769a]

here is the result
pip3 search pyqtchart
PyQtChart (5.9.2) - Python bindings for the Qt Charts library
INSTALLED: 5.9.1
LATEST: 5.9.2
You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

os is xubuntu 64 xfce

We should be able to figure this out. Sounds like python and QT5/QChart are crossed somewhere so we just have to find the difference.

So a couple things to try... do an 'ls -l /usr/bin/python3*' and see what comes back. I've seen similar issues with multiple versions of python installed (python3 points one place and python3.5 points another so the pip3 didn't install the packages in the correct dist location). Here's mine on Ubuntu 16.04:
lrwxrwxrwx 1 root root 9 May 27 07:35 /usr/bin/python3 -> python3.5
-rwxr-xr-x 2 root root 4456240 Sep 18 11:59 /usr/bin/python3.5

lrwxrwxrwx 1 root root 17 Mar 23 2016 /usr/bin/python3m-config -> python3.5m-config

The other thing to make troubleshooting quicker is you can just go 'python3' on the command-line and see if it'll even just let you do the import: 'from PyQt5.QtChart import QChart'. It'll either work or fail right there.

I've also heard of errors if there's an issue in QtCore. Try a 'pip3 search pyqt5'. Here's what mine shows as installed:
PyQt5 (5.9.2) - Python bindings for the Qt cross platform UI and application toolkit

Looks like you have the same things there. Let's try the import in a couple of python variations and see if we can figure out if it maybe didn't put it in all the distro's.

From a command-line type 'python3.5'. You should get a python interactive command prompt. type 'from PyQt5.QtChart import QChart' and see if it throws the same error (On Ubuntu 16.04 python 3.5 is the version it's installed but it's possible the python3 symlink may not be correct, this'll be a quick test).

Lets try forcing a reset...

sudo apt-get install --reinstall python3-pyqt5
pip3 install --upgrade --force-reinstall PyQtChart

[fe8769a]

sudo apt-get install --reinstall python3-pyqt5
pip3 install --upgrade --force-reinstall PyQtChart

worked fine except error message on pip3 version said it is 8.11 sould be 9.0.1

and still not working

very strange

[ghostop14]

This fixed a QT5 widgets issue in another project... see if this helps:

sudo apt-get install qt5-default

[ghostop14]

Tried it on a fresh Ubuntu 16.04.3 install and there were a couple items that seem unrelated that I added to the install instructions. See if these help at all too.

sudo apt-get install python3-tk
sudo pip3 install numpy matplotlib

[fe8769a]

I can't install a fresh ubuntu 16 , to much work on this linux to configure

Same error with previous line to install

[ghostop14]

I'm with you I hate having to rebuild or try a clean version. I'd prefer to fix whatever's going on. Just to see if it's something unique to that system, it may be worth rather than reloading, trying a fresh XUbuntu in a virtual machine (VMWare, virtual box, etc.). Do a quick base VM, nothing fancy, install the prerequisites and see if it works there. That way you don't have to disrupt that system at all.

[fe8769a]

Will do if I have some time left .. 2017-11-29 19:18 GMT+01:00 ghostop14 <notifications@github.com>:

Debian Stretch
The only way I managed to get sparrow-wifi to work was to carry out the following.
remove all python3 using apt
comment out references to stretch in /etc/apt/sources.list
add the sid repository
do an update
DO NOT DO AN UPGRADE!!!!
installed python3.5, pip etc
install all libraries
run program, it works
edit sources.list, uncomment stretch references, comment/remove sid reference
do an update (however all upgrades to python will now be invalid as debian's stretch release is behind the required release, the people on github mu-editor have had similiar issues)
your python3 executable is now python3.5, so a symbolic link will be required.

Have you solved this issue? I have the same issue with you.

[cody1028]

Have you solved this issue? I have the same issue with you.
python3.5 + PyQT5 ，have install the pyqtchart via pip3.

PyQT5 demo working well . I use pip3 list to check those thing. everything is fine.

but get ImportError: No module named 'PyQt5.QtChart

[ghostop14]

I can't reproduce the problem, so my suspicion is it's a fundamental Python issue on that system. I've tested it on Ubuntu 16, Kali linux, and a straight Debian 9, and everything seems to work fine from a standard OS installation.

[cody1028]

After a day and night. I have solve my issue.
I love to use PyQt5 and make some toys for myself. I use Python27 and Python35 in my Ubuntu16.
I install PyQt5 via apt-get before. and The version is old "PyQt5 5.5".
How to check the version of PyQt5 ?

$python2 
>>>from PyQt5 import QtCore ; 
>>>print(QtCore.PYQT_VERSION_STR).

$python3 
>>>from PyQt5 import QtCore ; 
>>>print(QtCore.PYQT_VERSION_STR).

I get both version string is 5.5.0. But I have check the pip3 list ,It has PyQt5 5.11. It means something is going wrong.
Now I have uninstall all PyQt5 on my system.
run : sudo find / -type d -iname "PyQt5*"
Looking for all about PyQt5 and rm -r them.

Following is : Install PyQT5/SIP for Py27 and Py35. Thay are all supported.

#For Py35 or later version:
pip3 install is avaliable.
Just run pip3 install PyQtChart. It will auto install "PyQt5" and "PyQt5-sip".
After installed. could check version with:
from PyQt5 import QtCore
print(QtCore.PYQT_VERSION_STR)
you will get a string version >5.11. That is a very new version.It is support the PyQtChart.
The PyQt5 version of apt-get is very old. about 5.5. It not support QtChart.

#For Py27: (no pip whl support. manual build sip and pyqt5, and not support PyQtChart)

1. build SIP: 2 part "python27-sip" and "PyQt5-sip".
   For Py27. need to build SIP and PyQt5-sip.
   https://www.riverbankcomputing.com/software/sip/download; (For now :2018-11 sip-4.19.13.tar)

---

"python27-sip"

python configure.py
make
make install

---

"PyQt5-sip".
make sure "python" is python2.7, We just install for python27

python configure.py --sip-module PyQt5.sip --no-tools
make
make install

---

2. build PyQT5 for Py27
   download PyQT5 shouce code.https://www.riverbankcomputing.com/software/pyqt/download5
   (For now :2018-11 PyQt5_gpl-5.11.3.zip)

following step will check "python27-sip" and system sip version first. manual chaeck run:sip -V.

python configure.py
make
make install

[ghostop14]

Excellent! It did seem like a local config issue. Hopefully that solution helps others.

I use pip to install PyQt5 for Python3.6, which turns out it also doesn't include QtChart. python3 -m pip install PyQt5==5.13.1
After that, I use python3 -m pip install PyQtChart, then Python can import QtChart, so I think pip install default method won't install QtChart.

this worked for me pip install PyQtChart==5.13.1
