Suddenly can no longer run test (due to breaking `]add Package` midway?)

Torkel · August 24, 2025, 4:39pm

I am developing a package, however, suddently, where I try to run

]test

I get a crash. A potential reason is that I pasted some code into the REPL which contained a using ... statement for a package I did not want to add to the package, however, I clicked the wrong button so the REPL automatically started to add it, and because I didn’t want this to happen I ctrl+C the process. After that I get this issue. Here is the error:

It does indeed look like you have a corrupted, probably truncated, registry file. You can probably solve it with

pkg> registry remove General
pkg> registry add

giordano · August 24, 2025, 5:46pm

Is this related to Running out of disk space on HPC without really doing anything unusual where you have reached a quota and your registry can’t be downloaded correctly?

Doing this actually yields exactly the same problem:

Not this, this is a different problem on an unrelated machine

Torkel · August 25, 2025, 11:00am

Actually, turns out ChatGPT managed to figure it out (!), this is the solution:

julia> import Pkg
julia> Pkg.Registry.rm("General"; force=true)   # ok if it says it's not present
julia> Pkg.Registry.add("General")
julia> Pkg.Registry.update()

GunnarFarneback · August 25, 2025, 12:43pm

That’s effectively the same as I proposed, apart from the last update, which isn’t needed to resolve the problem.

Torkel · August 25, 2025, 12:58pm

ok, there probably are some odd differences that had an effect here for some reason - hwen I ran yours I got the error again. Looking at the code it is the same principle though, maybe something silly like using ] mode caused the difference. Thanks for the help either way though!
