just did lein upgrade and it said it was successful but then gave me an error stack trace, and now my whole universe is broken 😞

grabbed the script afresh from http://leiningen.org, and it's still broken in a new way

This is in MacOS

don't know but sometimes sh -x lein will help diagnose

you can also install leiningen via brew, just fyi

Just tried renaming everything in my home directory starting with .lein but it didn't change things

are you running in a dir with a project.clj?

not that you need to be

I tried both in a project with a project.clj and not.

Here's what I get from that sh command (note that my .lein stuff is still renamed:

I've had issues with brew in the past but would like to try it... but don't see instructions for that on leiningen.org... What command would I use?

brew install leiningen

great...

if you don't use brew regularly you might also need to brew doctor and/or brew update

it's not obvious to me what's wrong from the script above

Sigh... here's the brew problem:

MacBook-Pro:bin leespector$ brew install leiningen
Error: /usr/local is not writable. You should change the ownership
and permissions of /usr/local back to your user account:
  sudo chown -R $(whoami) /usr/local
Warning: You are using OS X 10.14.
We do not provide support for this pre-release version.

Error: Unrecognized Mach-O load command: 0x32
MacBook-Pro:bin leespector$ sudo chown -R $(whoami) /usr/local
Password:
chown: /usr/local: Operation not permitted

will try brew doctor and brew update

doh

the latter updates brew, the former diagnoses any issues

Alas, both give me the same error about /usr/local, the suggest fix for which is "not permitted" when I try

hrm

sorry, gotta run

thanks. guess I will try to restore an old lein script from a backup and see if I can at least get back to work (though not on the thing that said it needed lein upgrade)

Restored my previous lein... whew, it works. Can't do the new stuff though!

And now lein upgrade works, whereas it didn't before... Not clear why! But I'm happy, I think. My brew mystery is still unresolved, and if anyone has insight into that I'd appreciate it.

I've forgotten how handles uberjar-ing when trying to generate classes. E.g. I've a generated class SomeType in SomeType.clj that I'm requiring in core.clj. When I lein uberjar I get a ClassNotFound exception. I've got an {:uberjar {:aot :all}} profile. What's the solution here?
