I was having trouble installing QGIS plugins because I kept hitting ModuleNotFoundError: No module named 'gdal'

Here's how I solved it

• QGIS -> Preferences -> System
• See "Current environment variables" window
• Note the path that is called PYTHONHOME (mine was /Applications/QGIS-LTR.app/Contents/MacOS )
• Open terminal
• Look for gdal using find /Applications/QGIS-LTR.app/Contents -type f -name "gdal.*"
• Note location. Mine was: `/Applications/QGIS-LTR.app/Contents/Resources/python/site-packages/GDAL-3.2.1-py3.8-macosx-10.13.0-x86_64.egg/osgeo/gdal.py

// update height, sending an extra 20 pixels to be safe
const mainElementHeight = (document.getElementsByTagName('body')[0].offsetHeight + 20).toString();
pymChild.sendMessage('height', mainElementHeight);

//// may need to add this:
// instantiate pym object
window.pymChild = new Child();

// or, for cnn rig, inside your draw function:
pymChild.sendMessage('height', initialHeight);
