Errors when trying the new package manager (0.7)

General Usage
1

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

julia> import HelloWorld

julia> HelloWorld.greet()
Hello World!
julia> 

(HelloWorld) pkg> add Random
 Resolving package versions...
  Updating `../Project.toml`
  [9a3f8284] + Random

(HelloWorld) pkg> add JSON
ERROR: The following package names could not be resolved:

Similarly on the next step:

(HelloWorld) pkg> add https://github.com/fredrikekre/ImportMacros.jl

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:

(v0.7) pkg> add https://github.com/fredrikekre/ImportMacros.jl

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!

That PR works for me, thanks!

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