TOML Parser error, while "Updating registry at ~/.julia/registries/General.toml"

[mgiugliano]

I just upgraded to 1.7.3, from 1.7.* and noticed the following bug.

My ~/.julia/config/startup.jl file contains

ENV["JULIA_EDITOR"] = "vim"
ENV["PYTHON"] = "/usr/local/bin/python3"
ENV["JUPYTER"]= "/usr/local/bin/jupyter"

println("Setup successful")

Unless I comment the println, I get this error while updating my packages: i.e. typing at Julia 1.7.3 REPL (macOS Monterey 12.4 (21F79) on MPB (16-inch, 2019)), ']' and then 'up':

When I comment the println, the error disappears and I get

I can't reproduce this. From the stracktrace it looks like it fails pasing a Artifacts.toml file, so might be related to some package you have in your environment. Can you provide more information?

[KristofferC]

I think you are running with --startup-file=yes which then triggers a bug in Pkg. You would have to remove the print command from your startup file or not run with --startup-file=yes.

@KristofferC

Indeed, I have Julia aliased to
julia --startup-file=yes --quiet

As I wrote in my issue report, I have removed println. I thought it was useful to report it anyway.

Following your instructions and running
function collect_artifacts(pkg_root::String; platform::AbstractPlatform=HostPlatform()) [...] returns an error:

ERROR: UndefVarError: AbstractPlatform not defined
Stacktrace:

   @ REPL[3]:1

I deleted my comment since I figured out what the problem was and it is no longer useful to test it. Something like JuliaLang/Pkg.jl#3109 should fix this.
