angularjs常量的导入/导出问题

我在angularjs 1.x应用程序中使用公共js模块系统，正在努力导入/导出常量。这就是我所拥有的

index.js

'use strict';
var angular = require('angular');    
module.exports = angular.module('constants', [])
    .constant('constant1', require('./constant1'))
     .constant('constant2', require('./constant2'))
    .constant('constant3', require('./constant3'))

'use strict';
 var SAMPLE1 =  { 'TEST1' : 100 , 'Test2': 200 }
 var SAMPLE2 =  300;
module.exports = SAMPLE1 ;
module.exports = SAMPLE2 ;

 'use strict';
      var SAMPLE3 =  { 'TEST3' : 400 , 'Test4': 500 }
      var SAMPLE4 =  600;
module.exports = SAMPLE3 ;
module.exports = SAMPLE4 ;

 'use strict';
      var SAMPLE5 =  { 'TEST5' : 700 , 'Test6': 800 }
      var SAMPLE6 =  900;
module.exports = SAMPLE5 ;
module.exports = SAMPLE6 ;

'use strict';
var angular = require('angular');
var myApp = angular.module('myApp', [
    require('./common/services').name,
    require('./components/constants').name
]);

constant1.js

'use strict';
var angular = require('angular');    
module.exports = angular.module('constants', [])
    .constant('constant1', require('./constant1'))
     .constant('constant2', require('./constant2'))
    .constant('constant3', require('./constant3'))

'use strict';
 var SAMPLE1 =  { 'TEST1' : 100 , 'Test2': 200 }
 var SAMPLE2 =  300;
module.exports = SAMPLE1 ;
module.exports = SAMPLE2 ;

 'use strict';
      var SAMPLE3 =  { 'TEST3' : 400 , 'Test4': 500 }
      var SAMPLE4 =  600;
module.exports = SAMPLE3 ;
module.exports = SAMPLE4 ;

 'use strict';
      var SAMPLE5 =  { 'TEST5' : 700 , 'Test6': 800 }
      var SAMPLE6 =  900;
module.exports = SAMPLE5 ;
module.exports = SAMPLE6 ;

'use strict';
var angular = require('angular');
var myApp = angular.module('myApp', [
    require('./common/services').name,
    require('./components/constants').name
]);

constant2.js

'use strict';
var angular = require('angular');    
module.exports = angular.module('constants', [])
    .constant('constant1', require('./constant1'))
     .constant('constant2', require('./constant2'))
    .constant('constant3', require('./constant3'))

'use strict';
 var SAMPLE1 =  { 'TEST1' : 100 , 'Test2': 200 }
 var SAMPLE2 =  300;
module.exports = SAMPLE1 ;
module.exports = SAMPLE2 ;

 'use strict';
      var SAMPLE3 =  { 'TEST3' : 400 , 'Test4': 500 }
      var SAMPLE4 =  600;
module.exports = SAMPLE3 ;
module.exports = SAMPLE4 ;

 'use strict';
      var SAMPLE5 =  { 'TEST5' : 700 , 'Test6': 800 }
      var SAMPLE6 =  900;
module.exports = SAMPLE5 ;
module.exports = SAMPLE6 ;

'use strict';
var angular = require('angular');
var myApp = angular.module('myApp', [
    require('./common/services').name,
    require('./components/constants').name
]);

constant3.js

'use strict';
var angular = require('angular');    
module.exports = angular.module('constants', [])
    .constant('constant1', require('./constant1'))
     .constant('constant2', require('./constant2'))
    .constant('constant3', require('./constant3'))

'use strict';
 var SAMPLE1 =  { 'TEST1' : 100 , 'Test2': 200 }
 var SAMPLE2 =  300;
module.exports = SAMPLE1 ;
module.exports = SAMPLE2 ;

 'use strict';
      var SAMPLE3 =  { 'TEST3' : 400 , 'Test4': 500 }
      var SAMPLE4 =  600;
module.exports = SAMPLE3 ;
module.exports = SAMPLE4 ;

 'use strict';
      var SAMPLE5 =  { 'TEST5' : 700 , 'Test6': 800 }
      var SAMPLE6 =  900;
module.exports = SAMPLE5 ;
module.exports = SAMPLE6 ;

'use strict';
var angular = require('angular');
var myApp = angular.module('myApp', [
    require('./common/services').name,
    require('./components/constants').name
]);

app.module.js

'use strict';
var angular = require('angular');    
module.exports = angular.module('constants', [])
    .constant('constant1', require('./constant1'))
     .constant('constant2', require('./constant2'))
    .constant('constant3', require('./constant3'))

'use strict';
 var SAMPLE1 =  { 'TEST1' : 100 , 'Test2': 200 }
 var SAMPLE2 =  300;
module.exports = SAMPLE1 ;
module.exports = SAMPLE2 ;

 'use strict';
      var SAMPLE3 =  { 'TEST3' : 400 , 'Test4': 500 }
      var SAMPLE4 =  600;
module.exports = SAMPLE3 ;
module.exports = SAMPLE4 ;

 'use strict';
      var SAMPLE5 =  { 'TEST5' : 700 , 'Test6': 800 }
      var SAMPLE6 =  900;
module.exports = SAMPLE5 ;
module.exports = SAMPLE6 ;

'use strict';
var angular = require('angular');
var myApp = angular.module('myApp', [
    require('./common/services').name,
    require('./components/constants').name
]);

我在运行应用程序时遇到此错误

错误：$injector:unpr

---

未知提供者：KEYProvider它表示您在声明注入您的服务时出错

MyService

。如果要导出多个变量，必须编写

module.exports.var1=var1；module.exports.var2=var2

（或

exports.var1=var1；exports.var2=var2

），而不仅仅是

module.exports=var1；module.exports=var2，

，因为第二个赋值只会覆盖第一个赋值。稍后您使用

var1=require（'./file'）.var1

导入var1和

var2=require（'./file'）.var2

导入var2
