py37-meshio fails to destroot

[dgarnier (reinrag1a)]

Something seems to be off when installing for python3.7. Works fine for python3.8.

Relevant error from log is:

Its clear that /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_python_py-meshio/py37-meshio/work/destroot/opt/local/Library/Frameworks/Python.framework/Versions/3.7/bin

Indeed, if one then does:

sudo mkdir /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_python_py-meshio/py37-meshio/work/destroot/opt/local/Library/Frameworks/Python.framework/Versions/3.7/bin

the install completes.

I don't know why this fails for python37 and not python38. Seems like an issue in the upstream meshio, but maybe a workaround can be made as the fix is pretty easy.

This is rather strange.

I no longer have Python 3.7 installed on my build machine, but 3.8 and 3.9 both build as expected.

the current version is py-meshio @4.4.3 - do you still experience the problem with the PY37 subport or can this ticket be closed?
