leiningen install lein-noir failed

Question

I'm just starting learning Clojure and web programming. I've installed Leiningen 2.0.0-preview2 on Clojure 1.3.0 and it can create projects correctly. But I always got That's not a task. Use "lein help" to list all tasks. error when I ran lein plugin install lein-noir 1.2.1 to install noir.

I've also tried to added lein-noir as a :dev-dependencies into project.clj and ran lein deps but it did nothing.

Does anyone know what's the problem and how can I resolve it. Thanks a lot!

My environment:

• Mac OS X 10.6.8
• Java 6
• Leiningen 2.0.0-preview2

I've also tryed Leiningen 1.7 but got different error and someone said it's because leiningen 1.7 can only work with Clojure 1.2.x Here's the error when I use Leiningen 1.7:

Answer 1

If you have added lein-noir to .lein/profiles.clj like above you need to run the command : lein new noir yoursitename. Not lein noir new my-website !

Also add lein-noir "1.2.1"

Answer 2

Leiningen 2 is very new. Most of the documentation out there is still describing how to do things with leiningen 1.7.0. The ways you've tried to install lein-noir don't work with leiningen 2. The documentation describing how lein version 2 is different from lein 1.7.0 can be found here.

In a nutshell, you need to create a profiles.clj file in your ~/.lein directory. To specify you want to use lein-noir, your ~/.lein/profiles.clj file should look like:

{:user {:plugins [[lein-noir "1.2.1"]]}}

Now you can create a new noir project by typing:

lein new noir projectname
