Mac OS X Classpath issue in Getting Started?

[Josh Nursing]

I am being frustrated in trying out the latest Clojurescript release on Mac OS X Yosemite. Not sure what I am doing wrong. I follow the Getting Started instructions and get this error on launching "java -cp cljs.jar:src clojure.main build.clj"

"Exception in thread "main" java.io.FileNotFoundException: Could not locate cljs/closure'__init.class or cljs/closure'.clj on classpath:"

I'm using the JAR right now on OS X Yosemite with Java 8. Are you sure you downloaded the JAR correctly? A few people have mentioned incorrectly grabbing the JAR with curl/wget.

Thanks David,

Tried with a fresh download from the browser, the previous cljs.jar was 19644097 bytes and the new one is 19673805 bytes.

I get the same error with the new one. Is there a configuration lacking with my .profile which prevents Java from reaching closure? I have added the closure/compiler CLOJURESCRIPT_HOME path to CLASSPATH in ~/profile and sourced it but still no go on this one.

I guess I can fall back to using Leiningen or Boot to start new projects as well like before?

[David Nolen]

Many people on OS X have gone through the Quick Start without issue. `java -version` at the command line returns 8 I assume?

If you have some global CLASSPATH thing I would remove that. Not generally a good idea.

[Josh Nursing]

Yes, I had made sure yesterday to grab the latest Java. Removed the CLASSPATH, re-checked PATH and access to the bin and script, which are fine, but still no go for me.

lein new figwheel <myprojectname> followed by lein figwheel appears to work for me though.

[David Nolen]

And `java -cp cljs.jar clojure.main` drops you into a regular Clojure REPL?

David

[Josh Nursing]

Yes, that works and drops me in Clojure 1.6.0 with the user=> prompt.

[David Nolen]

I don't know what else to suggest other than you're going to need to try some experiments to figure out what going on, the Clojure REPL you started can help you:

(System/getProperty "java.class.path")

(require 'cljs.closure)

etc.

In your build.clj, does it start off with

(require 'cljs.closure')

?

I'm having the same issue, same config. Yosemite, java 8 and cljs r3126. Following the precise instructions of https://github.com/clojure/clojurescript/wiki/Quick-Start, but I get the same error. The complete error log looks like this:

Still missing critical information like the results of running the following after starting a _regular_ Clojure REPL with `java -cp cljs.jar clojure.main`:

(System/getProperty "java.class.path")

(require 'cljs.closure)

> Caused by: java.io.FileNotFoundException: Could not locate cljs/closure'__init.class or cljs/closure'.clj on classpath:

Is it possible you are trying (require 'cljs.closure')? That trailing ' should otherwise not be there. ' means quote in Clojure and is not a String.

[David Nolen]

Good catch and shame on me for not reading the precise error closely enough in both cases :)

Yes it look like in both cases you all have written:

(require 'cljs.closure')

which doesn't mean what you think in Clojure, but may seem familiar if you're used to JavaScript. The right thing is:

(require 'cljs.closure)

Updating the QS with this gotcha since it's happened twice already.

That was it, solved for me now. Silly that I didn't see it before.

Thanks!

I fell into the same trap today following your "Optimizing ClojureScript Function Invocation" article. And had the same trailing ' there after copy-pasting from browser to vim. Seems like some over-eager vim bundle is closing that ' for me automatically.

Just fyi for anyone else ending up here from Google searches :)
