I want to update a package to the most recent version. For some reason, the most recent version does not seem to be recognized. Here is an example using an empty environment:
(@v1.6) pkg> st
Status `~/.julia/environments/v1.6/Project.toml` (empty project)
(@v1.6) pkg> add DifferentialEvolutionMCMC @v0.5.11
Resolving package versions...
ERROR: Unsatisfiable requirements detected for package DifferentialEvolutionMCMC [607db5a9]:
DifferentialEvolutionMCMC [607db5a9] log:
├─possible versions are: 0.1.0-0.5.9 or uninstalled
└─restricted to versions 0.5.11 by an explicit requirement — no versions left
When I add without specifying a version, v0.5.9 is installed:
(@v1.6) pkg> st
Status `~/.julia/environments/v1.6/Project.toml`
[607db5a9] DifferentialEvolutionMCMC v0.5.9
What would cause this to happen?
