I am going to define my model in require js and i need knockout and knockout validation plugin in my module and also jquery .

define(["knockout","jquery","knockout.validation"], function (ko,$,validation) {
  // knockout model here with some knockout validation 

    return function SignUpViewModel() {
    var self = this;
    self.name = ko.observable();
    self.email = ko.observable().extend({ required: true });
    self.password = ko.observable().extend({
       required: true,
       minLength: 6
   });
   self.confirmPassword = ko.observable().extend({ mustEqual: self.password() });
   self.company = ko.observable();
   self.availableCountries = ko.observableArray(['Pakistan', 'USA', 'Egypt', 'UAE']);
   self.selectedCountry = ko.observable();
   self.errors = ko.validation.group(self);
   }           
 });

But when i run this i got the following error . 

Uncaught ReferenceError: ko is not defined

i also try to debug and found that all other librariesknockout, jquery are loading perfectly .

and here is my config portion 

require.config({
  baseUrl: "/Scripts",
  paths: {
    "Signup" : "Signup",
    "knockout": "knockout-2.3.0",
    "knockout.validation": "knockout.validation",
    "jquery": "require-jquery"
    }
});

你的模型适合我，这是我的要求配置：

requirejs.config({
  baseUrl: '/Scripts',
  paths: {
    'jquery': 'jquery-1.9.1.min',
    'knockout' : 'knockout-2.3.0',
  }
});
// myModel.js is the file containing your model code.
require( ["myModel", "knockout"], function(model, ko){
  ko.applyBindings(new model());
});

myModel.js

define(["knockout","jquery","knockout.validation"], function (ko,$,validation) {
// knockout model here with some knockout validation 

  return function SignUpViewModel() {
    var self = this;
    self.name = ko.observable();
    self.email = ko.observable().extend({ required: true });
    self.password = ko.observable().extend({
       required: true,
       minLength: 6
    });
    self.confirmPassword = ko.observable().extend({ mustEqual: self.password() });
    self.company = ko.observable();
    self.availableCountries = ko.observableArray(['Pakistan', 'USA', 'Egypt', 'UAE']);
    self.selectedCountry = ko.observable();
    self.errors = ko.validation.group(self);
  };           
});

而且您不再需要require-jquery了，因为jQuery 在检测到 AMD/RequireJS 时定义了命名的 AMD 模块“jquery”（全部小写）。
