I tried it myself under Anaconda 3 environment without Mingw and Msys and
it shows the same error. (The install page says it requires Mingw. If you
don't have it, please refer to
http://getfem.org/install/install_windows.html ) It seems that the python
script cannot read the cpython library file ( _
getfem.cpython-37m-x86_64-linux-gnu.so, I believe the file name depends on
an environment you are working).
You might wan to try this with the pre-compiled packages
(getfem5.3win-amd64-py3.7.exe) or under Windows Subsystem for Linux too. It
would be much simpler than configuring this under Mingw and Msys. It works
well for me.
