I'm following https://github.com/supermodel/supermodel-cli#getting-started. Everything went well till supermodel model create MyModel. It throw an error:

/usr/local/lib/node_modules/@supermodel/cli/build/src/commands/model/create.js:35
    var modelFileName = superlib.camelize(basename);
                                 ^
