Unfortunately, I have not yet figured out the problem. I ended up successfully installing everything on another computer (macOS Mojave 10.14.6), leading me to believe it is a compatibility issue...

Hmm, sounds like you've done all the steps that I did to get it to work. I would just double-check that you put the path to the right plinkio folder,...

I have this same problem. OP, were you able to resolve this?

I found the solution in a closed issue (issue #15): https://github.com/dipetkov/eems/issues/15
