ImportError: cannot import name JSONDecodeError about fooof

Hey! Thanks for trying it out!

That is a new error to me. Which version of Python are you using?

Given that error, it would appear that we do have a minimum version required for json, but not having encountered this before, I'm not sure what version that is, and whether we can relax that on our end, or whether you will perhaps need a newer version of Python.

I am using Python 2.7.13. Or was -- I changed my version of Python to 3.6.0 and it just worked.

I went back to 2.7.13 and found the version of json, which is 2.0.9 in that installation. And then I went to 3.6.0, and printed the json version, and it's also 2.0.9! I wonder if there's something else going on between Python and this json version.

Anyway, thanks for suggesting to upgrade.

Ahh, okay - yeh, so it does require python3 to run properly, in particular 3.5 & 3.6.

I'm not too clear on the version numbering for the json module in particular, but in the python3 json docs it does note that the JSONDecodeError is new in 3.5, so it does seem it's just not available in the older 2.7 json module (mentioned in docs here: https://docs.python.org/3/library/json.html?highlight=json#json.JSONDecodeError).

I'm somewhat surprised that that is the first error that pops up when trying to run with 2.7, and it is not particularly helpful regarding the underling problem. We should add a more explicit check that will fail informatively when using a too early version of python.

Now that you have it up and running, please do let us now of any other comments or quirks you find as you test it out!

Absolutely! Thanks Tom
