node.js - RedisStore.prototype.__proto__ = Store.prototype

Question

我没有 NodeJs 经验。我正在尝试使用 node 命令从命令提示符运行 app.js 文件，但收到此错误

 D:\Imports\sparkleshare-dashboard\node_modules\connect-redis\lib\connect-redis.j
s:96
  RedisStore.prototype.__proto__ = Store.prototype;
                                        ^

已修复:我将代码更改为:

var session = require('express-session')
, RedisStore = require('connect-redis')(session);
