Attempting to instantiate an old environment I get a number of packages that fail with the error in the subject. The trace information that is printed out doesn’t offer any clue I can understand about the actual source of the problem.
I would appreciate any advice on how to diagnose the problem, or even to solve it 
This is something I was working on a year or two ago, on a different system and earlier julia and packages. My overall plan was to first get it working with the package versions at the time, and then update the packages and my code as necessary.
Operations are inside VSCode with julia 1.7.2. Project.toml is at the bottom of this message; it uses UUIDs for the version specification.
Some notes about the output that follows:
- The very first item seems to list 2 different log files. The first exists, but is empty. I looked for the 2nd assuming I should replace the end of the 1st file name, but don’t see it.
- What happens after re-resolving?
- The 2nd round errors, after
Pkg.precompile()are chattier, but not helpfully so; the stack trace seems to be for the precompiler failing, not what it failed on.

Basically the same error is repeated for each of the failing packages.

.) I said yes, and a large number of builds and (I think) upgrades followed. After that I could
