在Mac OS X中安装Leiningen 2.X.

Question

I'm using leiningen ver 1.X, and I'm trying to update it to ver 2.X.

As is written in this site , I downloaded the script as "lein2", but when I tried to run the "lein2" command, I get this error message.

Could not find artifact lein-newnew:lein-newnew:pom:0.3.4 in central (http://repo1.maven.org/maven2)
Could not transfer artifact lein-newnew:lein-newnew:pom:0.3.4 from/to clojars (https://clojars.org/repo/): Specified destination directory cannot be created: /Users/smcho/.m2/repository/lein-newnew/lein-newnew/0.3.4

It seems that the server doesn't respond, but I'm not sure. What might be wrong? I use Mac OS X 10.7.4.

Answer 1

The ~/.m2/repository and ~/.m2/repository/org directories are root owned so that I couldn't get an access to create subdirectories beneath it. After changing the ownership, everything works fine. I guess I used root privilege when I excited 1.X version of leiningen.

Answer 2

brew has a formula for leiningen.

> brew update
> brew install leiningen
> lein -v
Leiningen 2.5.3 on Java 1.8.0_45 Java HotSpot(TM) 64-Bit Server VM
