Question

What is the correct way to install Leiningen on Windows? I grabbed the script and did the self install. Tried to run lein new tutorial and got this error:

Exception in thread “main” java.lang.RuntimeException: java.io.FileNotFoundExcep
tion: Could not locate leiningen/core__init.class or leiningen/core.clj on class

After getting this I added this to my class path:
C:\Users\Owner.lein\self-installs\leiningen-2.0.0-SNAPSHOT-standalone.jar
Ran again and got same error. What am I missing?

UPDATE
Went with 1.6.2 version based off suggestion from @mtyaka

Now I get this error:

Answer 1

It looks like you are trying to install leiningen 2 which is currently in the middle of development and is not really ready yet. I wouldn’t be surprised if self-install doesn’t work at the moment, especially on Windows.

Please try the stable version of lein.bat (currently 1.6.2).
