I don’t think that deleting the .julia directory is a good idea. Generally speaking, “delete anything and restart from scratch” is not a good advice ![]()
The message “TreeViews has no known versions” is very strange. Try:
(@v1.4) pkg> st -m Atom
The answer should be something like that:
Status `~/.julia/environments/v1.4/Manifest.toml`
[c52e3926] Atom v0.12.10
[...]
[e5e0dc1b] Juno v0.8.1
[7c4cb9fa] LNR v0.2.1
[50d2b5c4] Lazy v0.15.0
[...]
[a2a6695c] TreeViews v0.3.0
