Issue installing qmesh

[acse-ej321]

@jhill1
I am running into install issues when trying to run 'pip install qmesh' for qmesh. I am hoping to run the example scripts found in: https://github.com/thetisproject/thetis/tree/master/examples/north_sea. The issue seems to be related to a try / except block in the setup.py around line 108, checking the gmsh version, and seems to be something that was depreciated between 2.7 and 3.x.

Note to self: Update docs to qmesh3 in this example

I have problems installing qmesh as well. Seems that something is going wrong with building the wheel. Would be great if someone could help me out!

The qmesh package expects a gmsh executable in your path. Second thing it expects is a functioning python interface to qgis, i.e. you need to be able to import qgis. If you still have issues maybe better to open a separate issue.
@jhill1: what is the best place to raise issues regarding qmesh3 ?

[jhill1]

Thanks for reporting this. Best reporting to the new github page (so new it doesn't actually have code yet): https://github.com/orgs/qmesh3/

I also note @Sijbrandb you're attempting this on Windows. qmesh3 hasn't been tested on Windows at all. So please do open this as a separate issue as the original is on thetis examples and moving to a new qmesh (whereas your issue is an installation one)
