Done installing smart packages

Now when I run it $> mrt I get the following output:

Stand back while Meteorite does its thing

Done installing smart packages

Ok, everything's ready. Here comes Meteor!

[[[[[ ~/tmp/test ]]]]]

Now when I do meteor update the problem remains. Even if I first do meteor update and then mrt update I end up with the same result. Any suggestions ?

Answer 1

The problem is that running mrt update has updated iron:router to the latest version (0.9.1), which is only compatible with meteor 0.9 release candidates (see the explanation here : Installation issues with iron-router (newest) on Windows 7 x64 (Meteor 0.8.3)).

What you need to do is downgrading iron-router to 0.8.2 which is compatible with meteor 0.8.3.

To do so, you'll have to modify your smart.json like this :

{
  "packages": {
    "iron-router":{
      "version": "0.8.2"
    }
}

Then clean your project by removing smart.lock and run mrt install to make sure meteorite has accounted for the change.

If everything is OK the iron-router version symlinked in your project packages folder should point to iron-router@0.8.2
