When i tried to install JSON, error message pop up, not sure how to fix it.
Try to install JSON3, it is the package I usually use.
Very odd, works for me in v1.4 on Windows - maybe nuke your
.julia folder and start again?
pkg> status print? i.e. what else do you have installed that might have conflicting JSON requirements?
PS. Please don’t post screenshots. Copy and paste the text, and post it as quoted code.
