Unsatisfiable package requirements
When adding packages to your project, you might see an issue explaining that there is a conflict between requirements of different packages. This might mean you simply need to use a different version and then try adding the package (or resolving or instantiating) again.
Other times, the issue might be because the registry that your packages come from needs to be reset.
(local) pkg> add Banyan
Resolving package versions...
ERROR: Unsatisfiable requirements detected for package Banyan [706d138b]:
Banyan [706d138b] log:
├─Banyan [706d138b] has no known versions!
└─restricted to versions * by an explicit requirement — no versions left

ERROR: Unsatisfiable requirements detected for package AWSS3 [1c724243]:
AWSS3 [1c724243] log:
├─AWSS3 [1c724243] has no known versions!
└─restricted to versions 0.7.7 by an explicit requirement — no versions left
The simplest resolution
(source)
might be removing the General registry and then
trying again.
(@v1.5) pkg> registry rm General
Removing registry `General` from ~/.julia/registries/General
Remember that you can enter the pkg> mode by typing ] in the Julia REPL.
When entering the Julia REPL, you may want to just type julia but other
times you want to use the Julia environment in a particular directory with
julia --project=..
Cannot merge projects
If you get an ERROR: can not merge projects, it might mean that you ned to
delete one or more Manifest.toml files (maybe in a test/ directory)
and potentially also apply the Pkg.dev (or ] dev) command again to use the
local copies of packages.
