I'm trying to run npx shadow-cljs server but I'm running into an error:

thheller19:03:40

that error you get when shadow-cljs is not on the classpath

Eva O19:03:55

How do I add it to the classpath?

thheller19:03:59

might be some bad cache or maybe the jar download was aborted and is incomplete?

thheller19:03:06

try deleting your .cpcache folder

thheller19:03:24

when that doesn't work delete ~/.m2/repository/thheller/shadow-cljs

thheller19:03:28

otherwise looks fine

Eva O19:03:40

Same error except it also includes WARNING: Specified aliases are undeclared: [:-A]

thheller19:03:27

hmm weird. which OS is this?

thheller19:03:33

this is a regular tools.deps install I assume? maybe thats outdated or broken somehow?

Eva O19:03:05

MacOS 12.2.1

thheller19:03:05

via :deps you are telling shadow-cljs to run tools.deps clojure command. that should be fine but may break if thats not the standard thing

Eva O19:03:33

What is tools.deps?

thheller19:03:34

you can try clojure -A:dev -M -m shadow.cljs.devtools.cli server

Eva O19:03:07

Same error

thheller19:03:19

what is clojure?

thheller19:03:06

what is the clojure command for you?

thheller19:03:57

dunno how you installed it

Eva O20:03:07

Both clojure and clj give the same output

Eva O20:03:26

The weird thing is that it works in other projects. It's just this new one that's breaking

thheller20:03:57

clj -version?

thheller20:03:02

what I have seen before is some not-visible unicode char as the first char in deps.edn

thheller20:03:34

or somewhere else? forgot how to figure that out though

Eva O20:03:50

Execution error (FileNotFoundException) at java.io.FileInputStream/open0 (FileInputStream.java:-2).
-version (No such file or directory)

Eva O20:03:05

That's what I get when I run clj -version

thheller20:03:22

hmm there is definitely something weird then? might just be super old? I get 

$ clj -version
Clojure CLI version 1.10.3.855

thheller20:03:10

maybe clj -Sdescribe?

Eva O20:03:18

My version is 1.11.0. I checked by just running clj

thheller20:03:34

no, that is the clojure version. not the version of the clj tool itself

Eva O20:03:57

clj -Sdescribe
{:version "1.10.1.561"

thheller20:03:13

hmm yeah that is kinda old

thheller20:03:28

maybe try upgrading that

Eva O20:03:16

I don't remember how I initially installed clojure since it was a long time ago. Since I'm using a Mac, I would assume I did it through brew. However brew upgrade clojure/tools/clojure doesn't work. I'm going to try to reinstall with brew. Hopefully it doesn't clobber it

thheller20:03:05

I'm not sure why it wouldn't work either. maybe try asking in #tools-deps. that error about missing alias is definitely weird

thheller20:03:11

seems declared fine to me but thats the root of the problem it seems

ag20:03:27

Does anyone know, when used with github actions, shadow-cljs doesn't cache jars that shadow uses, and they keep getting re-downloaded each time. Has anyone dealt with this?

thheller05:03:19

you need to setup caching yourself. I don't have a guide for that but I'm sure there is one. regular maven caching will do

FlavaDave23:03:15

trying to use amazon-cognito-identity-js and per the the table here https://shadow-cljs.github.io/docs/UsersGuide.html#_using_npm_packages I wrote 

(ns presentation.cognito.auth
  (:require ["amazon-cognito-identity-js" :refer (CognitoUserPool)]))
but whenever i try to use CognitoUserPool it says its an undeclared var

FlavaDave23:03:19

I also tried 

(ns presentation.cognito.auth
  (:require ["amazon-cognito-identity-js$default" :as CognitoUserPool]))
but that didnt work either

Drew Verlee02:03:36

Can you share the js equivalent your working from? I always have to just pattern match from what I'm given to what's on that table.

thheller21:03:43

likely is 

(ns presentation.cognito.auth
  (:require ["amazon-cognito-identity-js$default" :refer (CognitoUserPool)]))

thheller21:03:55

note not :as since CognitoUserPool is not the default export

thheller21:03:32

note that the docs have a section on how to figure this out just below the examples

thheller21:03:17

that should probably be more prominent but just at the end of that section

FlavaDave21:03:34

hmmm i changed it to your suggestion and get 

:shadow.cljs.devtools.server.util/handle-ex - {:msg {:op :cljs-compile, :input {:code "(ns presentation.cognito.auth\n  (:require [\"amazon-cognito-identity-js$default\" :refer (CognitoUserPool) ]))", :ns presentation.cognito.auth, :repl true}, :include-init false, :call-id 7, :from 10}}
StackOverflowError 
        shadow.build.npm/find-resource (npm.clj:726)
when i try to evaluate the namespace

FlavaDave21:03:33

iā€™ll read those docs more and try an figure it out

kardan05:03:34

I have this in a toy project (but, should work) (ns ā€¦ (:require [ā€œamazon-cognito-identity-jsā€ :refer [AuthenticationDetails CognitoUserPool CognitoUserAttribute CognitoUser]] ))

thheller06:03:48

@UF41YH1CM which shadow-cljs version do you use? the stackoverflow was a bug in 2.17.0 so upgrade if you use that

FlavaDave20:03:17

ahh yes i made the switch to 2.17.8 and it works perfectly now!
