errors with HNN GUI installation #324

Closed stephanie-r-jones closed 2 years ago

stephanie-r-jones commented 2 years ago

HNN GUI was working on my mac after pip installation but II haven't run it in a while and now ran into the following into errors:

Fatal Python error: initfsencoding: "unable to load the file system codec ModuleNotFoundError: No module named 'encodings' Current thread 0x000000010807f5c0 (most recent call first): Abort trap: 6

I then went back and ran a pre-install check and received the following warnings:

Checking PYTHONPATH environment variable is not set...warning NEURON libraries found in PYTHONPATH variable. This was used before the 'pip install' method. Make sure this matches the version used to compile HNN modules with 'make' PYTHONPATH=/Applications/NEURON-7.8/lib/python:

Checking PYTHONHOME environment variable is not set...warning

PYTHONHOME is set. This is not the recommended way to set the python environment. Make sure that this is the correct environment to run HNN. PYTHONHOME=/Applications/anaconda Fatal Python error: initfsencoding: unable to load the file system codec ModuleNotFoundError: No module named 'encodings'

Current thread 0x00000001079125c0 (most recent call first): Python version:

Checking NRN_PYLIB environment variable is not set...ok Checking for existing hnn directory...found Existing HNN source code directory found at /Users/stephaniejones/hnn_new Optional: use this directory instead of step "Download HNN source code"
