I’m trying out the new package manager, but get stuck following the docs here: [https://docs.julialang.org/en/latest/stdlib/Pkg.html#Adding-packages-to-the-project-1](https://docs.julialang.org/en/latest/stdlib/Pkg.html#Adding-packages-to-the-project-1)

```julia
julia> import HelloWorld

julia> HelloWorld.greet()

ERROR: The following package names could not be resolved:

```

Similarly on the next step:

```julia

```

Also the same thing happens when trying to install a package “normally”, i.e. not inside a “project”.

Something seems strange with your registry. Can you try to remove `.julia/registries` and try again.

This is what I get:

```julia

Yes, I think that was it. After doing a `git pull` in `.julia/registries/Uncurated` it now seems to work. I suspect I had a few month old version of the registries.

I have another one now:

Loading Revise should work now. A new Compat had to be tagged and propagated to the registry.

I’ll look into the precompile problem.

Ok, now with Compat at 0.65.1 the `using ...` works, but yes the `precompile` still errors. Thanks!

Thanks for this, just fixed an issue for me after I had removed and reinstalled Julia 1.0.1.
