CMake error while building and installing dolfinx c++ core

installation
32

Thank you so much! Looks like things are starting to work out now but somehow strange… When I start running the code, looks like there’s only one import error towards ufl:

(base) krizerator@Clarke:/mnt/d/A--X/Programming/Python$ python3 demo_poisson.py
Traceback (most recent call last):
  File "demo_poisson.py", line 72, in <module>
    import ufl
ModuleNotFoundError: No module named 'ufl'

Notice that this happens when I run it on the base. But when I run it in the venv mentioned in Problem about pyvista - #2 by dokken, then I get this:

(fenicsx-env) krizerator@Clarke:/mnt/d/A--X/Programming/Python$ python3 demo_poisson.py

Why would it be? And what could I do to fix the import problem? I already checked the ufl but it’s installed:
