Where does raco stores collections on macOS?

dannypsnl · December 30, 2021, 2:28am

I just found when I type raco install --auto xxx, it says missing xxx/yyy in

/home/Library/Racket/8.3/collects
/Applications/Racket v8.3/collects/

but end up I found xxx/yyy is existed in

/home/Library/Racket/8.3/pkgs

and there has no /home/Library/Racket/8.3/collects in my system.

Can you post the full transcript of the failed command? I think the reference to collects may be a red herring here?

dannypsnl · December 30, 2021, 6:43am

Sure, is raco pkg install --auto turnstile-lib

Sorry, I wasn't clear. By "transcript" I meant both the command and the command's output.

Ah! It looks like you have perhaps misspelled "turnstile" as "trunstile".

I'm guessing that you see this message when you try to run a program that begins with

#lang trunstile+
...

To fix this, make sure your program begins with the correct language name.

I agree that the error message in this case should be improved, and not make reference to collections directories in this way.

jbclements · December 30, 2021, 5:36pm

... though, to be clear, the error message does also make reference to 267 additional collections directories.

I believe that what you're really seeing here is the unfortunate combination of

a historical artifact, the existence of collections separate from packages, and
an ordering that puts the collection search path before the others.

For more information about collections, you can see

https://docs.racket-lang.org/reference/collects.html#(tech._collection)

... though to be clear, it appears to me that the fix for your issue is simply to spell the name of the language in the way expected by the package.

Oh god, I'm silly. Thanks for help!

jbclements · December 31, 2021, 8:43pm

No problem! If I had a nickel for every mistake like that I'd made, I'd be very rich.
