If you run into this issue please let me know what python path you have configured.

I've only seen this happen on Darwin 18.2.0 OS so far

I am getting this error too. Fresh install of Anaconda and VS Code on a mac. Installed the AREPL extension and I get the following error in a new document window:

Thanks for giving me the python path - For some reason one of 'stdout', 'stdin', 'stderr' is null after spawning the process and I'm not sure why. I just have a windows laptop at the moment but once I get back home I'll be able to test python paths on my ubuntu VM. In the meantime I would suggest using python3 instead of anaconda for AREPL if possible. AREPL doesn't support anaconda very well because the anaconda environment needs to be activated to work properly.

Thanks, I’ll give it a try!

note to self: https://github.com/extrabacon/python-shell/pull/191 might change the error - I'm guessing when that gets merged in the error would be "stdin not open for writting"
