Uninstall NEURON (use the uninstaller that comes with NEURON).
Make sure that your Python works.
Then reinstall NEURON and see if everything works properly.

Hi,

the problem occurs when the python executable is not in your Path environment variable. If you type

Code: Select all

python
in a terminal and get the python prompt, it should be OK. Else you have to locate python.exe and add that directory to your Path.

HTH,
Matthias

Ideally the NEURON installer should automatically discover an existing Python installation, but sometimes that doesn't work and it becomes necessary to manually edit the PATH.
