Question

我对MEAN堆栈很新。启动我的服务器＆gt;我正面临“TypeError：object is not function” node index.js。

.../master/server/app.js:47
require('./config/socketio')(socketio);
                            ^
TypeError: object is not a function

我的Index.js文件是

'use strict';

    // Set default node environment to development
var env = process.env.NODE_ENV = process.env.NODE_ENV || 'development';

if (env === 'development' || env === 'test') {
  // Register the Babel require hook
  require('babel-core/register');
}

// Export the application
exports = module.exports = require('./app');

App.js文件

/ ** *主要申请文件 * /

'use strict';

提前致谢。

您正在使用默认导出。您用来编译代码的任何内容（例如Babel或TypeScript）都可能通过在名为module.exports的{{1}}上添加属性来发出默认导出。

尝试写写default。

TypeError：object不是Node JS / socket.io中的函数
