Modern-cljs Tutorial 3. Problems with ring

[Juan Manuel Gimeno Illa]

I'm doing the modern-cljs tutorial and I'm stuck at part 3. The error is the same with my typed version and using a clone of the tutorial.

The error I find is:

λ >: lein ring server

And with the information provided I'm unable to find its source. Any idea?

Thanks,

I have a very strange situation. On my mac book air (where I was doing the ttutorial) it does not work. I have moved to my iMac and here it works.

Same JVM on both machines

java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

Any ideas?

[Mimmo Cosenza]

which lein/java versions you have?

$ lein version
$ javac -version

Do you have anything in your ~/.lein/profiles.clj?

It seems to be a problem of your environment….

I've deleted completely the .lein directory and now it works.

Thanks for your help !!!
