Unhelpful error message about failure to parse compatibility version #1853
Description
Since yesterday I can't update the global environment nor add new package:
(@v1.4) pkg> up
Updating registry at `~/.julia/registries/General`
Updating git-repo `https://github.com/JuliaRegistries/General.git`
ERROR: Could not parse compatibility version for dependency `julia`
I have no clue where the problem is, it would be great if the error message pointed the user to where the issue is (which project file).
The only thing I could do is to fire up Debugger.jl to at least get a stacktrace:
julia> using Debugger, Pkg
julia> @enter Pkg.update()
[ Info: tracking Pkg
In #up#44(kwargs, ) at /usr/share/julia/stdlib/v1.4/Pkg/src/API.jl:193

>193 up(; kwargs...) = up(PackageSpec[]; kwargs...)

195 up(pkgs::Vector{<:AbstractString}; kwargs...) = up([PackageSpec(pkg) for pkg in pkgs]; kwargs...)
