I had to change the version of my npm app from 0.1 to 0.0.1 in order for npm not to do this.
$ npm install
npm ERR! install Couldn't read dependencies

For completeness here's the working json
$ cat package.json
{
"name": "ply",
"description": "ply server for local dev testing deployments",
"version": "0.0.1",
"private": true,
"dependencies": {
"express": "3.x"
}
}
version used to be "0.1" when it made the error.
Is this some sort of API/ABI compatibility versioning concept requiring 3 sets of version numbers? Why is the error message not more friendly w.r.t. this?
