I am working on magento version 2.1.3 and have a custom theme shoppersbay. For some js files it gives error like

Unable to resolve the source file for
'frontend/Smartwave/shoppersbay/en_US/Magento_ConfigurableProduct/js/variations/paging/sizes.js'
0 /home4/shoppoz8/public_html/shoppersbay/vendor/magento/framework/App/StaticResource.php(97): MagentoFrameworkViewAssetFile->getSourceFile()
1 /home4/shoppoz8/public_html/shoppersbay/vendor/magento/framework/App/Bootstrap.php(258):
MagentoFrameworkAppStaticResource->launch()
2 /home4/shoppoz8/public_html/shoppersbay/pub/static.php(13): MagentoFrameworkAppBootstrap->run(Object(MagentoFrameworkAppStaticResource))
3 main

I searched for the file sizes.js but i didn't find any in theme and in vendor directory. How can i resolve it?

Because that file sizes.js is not belong to frontend scope. It belongs to adminhtml.

magento/module-configurable-product/view/adminhtml/web/js/variations/paging/sizes.js

/**

 */
define([
 'Magento_Ui/js/grid/paging/sizes'
], function (Sizes) 
 'use strict';

 return Sizes.extend(
 defaults: 
 excludedOptions: ['100', '200']
 ,

 /**
 * @override
 */
 initialize: function () 
 this._super();

 this.excludedOptions.forEach(function (excludedOption) 
 delete this.options[excludedOption];
 , this);
 this.updateArray();

 return this;
 
 );
);

Solution for your problem is delete any references to sizes.js in your custom theme. And asks the vendor to fix it, obviously :)
