我用的版本是ext6.0.1企业版。以下测试代码和我的项目代码运行报错一致：

<!DOCTYPE html>
<html>

   <head>
       <meta charset="UTF-8">
       <title></title>
       <link rel="stylesheet" href="ext-6.0.1/build/classic/theme-classic/resources/theme-classic-all.css" />
       <script type="text/javascript" src="ext-6.0.1/build/ext-all.js"></script>
       <script type="text/javascript" src="ext-6.0.1/packages/ux/classic/src/data/PagingMemoryProxy.js"></script>
麻烦大佬测试下是哪里的问题，，已经卡住两天了

以下是PagingMemoryProxy.js所用源码

/**
* Paging Memory Proxy, allows to use paging grid with in memory dataset
*/
Ext.define('Ext.ux.data.PagingMemoryProxy', {
extend: 'Ext.data.proxy.Memory',
alias: 'proxy.pagingmemory',
alternateClassName: 'Ext.data.PagingMemoryProxy',

constructor: function() {
Ext.log.warn('Ext.ux.data.PagingMemoryProxy functionality has been merged into Ext.data.proxy.Memory by using the enablePaging flag.');
this.callParent(arguments);
},

read : function(operation, callback, scope){
var reader = this.getReader(),
result = reader.read(this.data),
sorters, filters, sorterFn, records;

scope = scope || this;
// filtering
filters = operation.filters;
if (filters.length > 0) {
//at this point we have an array of Ext.util.Filter objects to filter with,
//so here we construct a function that combines these filters by ANDing them together
records = [];

Ext.each(result.records, function(record) {
var isMatch = true,
length = filters.length,
i;

for (i = 0; i < length; i++) {
var filter = filters[i],
fn = filter.filterFn,
scope = filter.scope;

isMatch = isMatch && fn.call(scope, record);
}
if (isMatch) {
records.push(record);
}
}, this);

result.records = records;
result.totalRecords = result.total = records.length;
}

// sorting
sorters = operation.sorters;
if (sorters.length > 0) {
//construct an amalgamated sorter function which combines all of the Sorters passed
sorterFn = function(r1, r2) {
var result = sorters[0].sort(r1, r2),
length = sorters.length,
i;

//if we have more than one sorter, OR any additional sorter functions together
for (i = 1; i < length; i++) {
result = result || sorters[i].sort.call(this, r1, r2);
}

return result;
};

result.records.sort(sorterFn);
}

// paging (use undefined cause start can also be 0 (thus false))
if (operation.start !== undefined && operation.limit !== undefined) {
result.records = result.records.slice(operation.start, operation.start + operation.limit);
result.count = result.records.length;
}

Ext.apply(operation, {
resultSet: result
});

operation.setCompleted();
operation.setSuccessful();

Ext.Function.defer(function () {
Ext.callback(callback, scope, [operation]);
}, 10);
}
});
