Node.js如何设置MaxListeners（）

我以前从未使用过node.js。但是按照here中的步骤进行solr安全代理。一切正常，但它给了我这个警告。我知道我必须设置最大侦听器，但是不知道如何以及在哪里做。请帮助我。

(node) warning: possible EventEmitter memory leak detected. 11 listeners added. Use emitter.setMaxListeners() to increase limit.

您在调用setMaxListeners（或setMaxListeners）的同一对象上调用addListener，该对象将是addListener。

但是，如果您确实确实存在发射器内存泄漏（而不是碰巧需要11个侦​​听器，而不再需要），那么您需要从根本上解决该问题-提高限制将无济于事。
