I am running Julia 1.1 and Windows 10. I can’t seem to install StatsBase 0.30 as I get this error when I `]pin StatsBase@0.30`.

The error seems to suggest that Optim.jl restricts StatsBase to 0.29 but when I looked at the REQUIRE for Optim.jl it simply says StatsBase without specifying a version. So what’s stopping the upgrade? I can remove Optim and whatever other package but then why can’t I just upgrade StatsBase?

```julia

I think the problem is that StatsBase has migrated to the new `Project.toml` based system but not Optim. I think you either have to add a `Project.toml` to your Optim copy or remove the one in StatsBase.

That should not matter.

The problem is that Optim does not support StatsBase 0.30 (according to the registry): [https://github.com/JuliaRegistries/General/blob/37cf47c862d8ae34197d14cf52741965e2c9f658/O/Optim/Compat.toml#L44](https://github.com/JuliaRegistries/General/blob/37cf47c862d8ae34197d14cf52741965e2c9f658/O/Optim/Compat.toml#L44)

It seems to be resolved now.

In my case, it was due to Distributions package. I first installed Distributions and the version got installed was 0.19. When I tried to install StatsBase, it gave a similar error. So I removed Distributions and then reinstalled StatsBase. It went fine. Subsequently I reinstalled Distributions and the package version installed is 0.18.
