3.6 64-bit
- If on 64-bit, is your QLIC set? Please provide output env | grep QLIC on linux/macOS, or set|grep QLIC on Windows.

```No, but my license file is under `$VIRTUAL_EVN/q````

Did you use virtual environment to install PyQ? If not, why?
- yes
Where is your QHOME? Please provide output env | grep QHOME on linux/macOS, or set|grep QHOME on Windows. QHOME=/Users/xiangpeng/venv37/q
Do you use Conda? If so, what version? No

Workaround

I just updated my python3.7 and re-created virtual env following: https://github.com/KxSystems/pyq/issues/131#issuecomment-627361984 It looks like python tries to look for package from system instead of inside virtual env. Meanwhile, pyq has no problem to import package from virtual env. Screenshot 2020-05-12 at 11 27 24 PM

If you know workaround, please provide it here.

This has been resolved in PyQ 5.0. Please update to it using pip install -U pyq.

I’m going to keep this issue open until it is resolved for Python 3.7+.

No. Only workaround I can provide to you is to use python 3.6 and older version of the virutalenv to create venv.

brew install sashkab/python/python@3.6
/usr/local/opt/python@3.6/bin/python3.6 -mpip install -U virtualenv==16.7.9
/usr/local/opt/python@3.6/bin/python3.6 -mvirtualenv pyq
source pyq/bin/activate
python3.6 -mpip install -U pip setuptools wheel
unzip Downloads/m64.zip -d $VIRTUAL_ENV/q
cp q64/kc.lic $VIRTUAL_ENV/q/
python3.6 -mpip install pyq
QHOME=$VIRTUAL_ENV/q $VIRTUAL_ENV/q/m64/q

I was able to reproduce this, and opened internal issue 1068. No ETA on this.
