Question

我试图学习流星并通过流星提示，以及js文件中的第二行＆＃34; PlayersList = new Mongo.Collection（＆＃39; players＆＃39;）;＆＃34 ;导致它无法运行。它说我在子目录中有一个重复的文件，但我不确定这是怎么可能的，因为我在那里只有三个文件是leaderboard.css，leaderboard.html和leaderboard.js。

我不确定如何格式化以使其更具可读性，感谢您的帮助！

这是日志：

Answer 1

通常，当您遇到A method named '/member/insert' is a lready defined之类的错误时，就意味着您创建的new Mongo.Collection('member')次数超过了一次。

也许您是在Array.forEach函数中执行此操作（如果您的数组包含多个元素，则会多次调用）。

从错误日志中看，它似乎是由fn _.each(array,fn) server\boot.js引起的。{/ p>
