I assume you are using Atom. I experienced same problem. I had to go and press “control + comma” on Windows, to get to “Settings”. Then I click “open config folder”
Then I deleted all related to Julia:
Since sometimes “uninstall” under “Packages” in “Settings” would fail. Then I would go and install “uber-juno” and then before closing Atom I would go to the settings of “uber-juno” and tick off:
(Tick off, means REMOVE the “yes”, so it becomes blank)
Then I would restart Atom and it would reinstall everything - then I think I had to close and open and everything was there.
Kind regards
