Problems with Version Gmsh (version >=2) and Fipy

Question

I am new in FiPy and I have problems with the example:

I get the error:

EnviromentError: Gmsh version must be >=2.0

I tried already some things that were posted about two years ago, but that did not help, e.g., EnvironmentError: Gmsh version must be >= 2.0 and Gmsh mesh parallel execution in fipy

I already checked my versions: Fipy: 3.3 pygmsh: 5.0.2 spyder 3.3.6 Python: 2.7 gmsh: 4.1.1

I am working on Windows 10 64Bit.

Thank you very much for your help.

It would help if you listed the things that you already tried (maybe link to the post from two years ago). And you'll also get more help if you post some of the code that's not working. At best, a minimal, reproducible example: https://stackoverflow.com/help/minimal-reproducible-example. — Druckles, Aug 27 '19 at 11:28
What is the result of typing `gmsh -version` at the command line? — jeguyer, Aug 27 '19 at 12:43
@Druckles, thank you for your advice. Here are the posts from two years ago: https://stackoverflow.com/questions/45405916/environmenterror-gmsh-version-must-be-2-0. And https://stackoverflow.com/questions/39831494/gmsh-mesh-parallel-execution-in-fipy. — KristaQ, Aug 27 '19 at 15:36
My guess is that gmsh is not on the execution path when you run FiPy. Try `gmsh -version` from within the Spyder environment. — jeguyer, Aug 27 '19 at 17:14
Does this answer your question? [EnvironmentError: Gmsh version must be >= 2.0](https://stackoverflow.com/questions/45405916/environmenterror-gmsh-version-must-be-2-0) — Mark Rotteveel, Jan 04 '20 at 10:47

Like jeguyer mentioned: gmsh must be on the execution path when runs FiPy. That solved the problem.

I copied the entirely gmsh folder into the Anaconda3\Scripts folder and since then everything worked fine.
