NodeJs循环加载路由：无法读取未定义的属性'indexOf'

Question

尝试使用循环加载routes文件夹中的所有路径文件，我收到此错误：

  

无法读取未定义

的属性'indexOf'

代码：

77 var routes = {};
78 var routeFiles = fs.readdirSync('./routes');
79 for(var i = 0; i < routeFiles.length; i++){
80    if (routeFiles[i].match(/\.js$/) !== null && routeFiles[i] !== 'index.js') {
81        var name = routeFiles[i].replace('.js', '');
82        try {
83            routes[name] = require('./routes/' + name)(passport);
84        } catch (e) {
85            console.log(e.stack);
86        }
87    }
88}

错误出现在这一行：

routes[name] = require('./routes/' + name)(passport);

当我在没有循环的情况下编写它时它工作正常，例如：

var name = 'main';
routes[name] = require('./routes/' + name)(passport);

修改

添加了行号。
