当我添加了 cnjj-log 和global-log的日志后启动项目就报错了

这是报错的堆栈

把我加的那两个日志配置删除，启动就不会报上面的错

from pinus.

log4js-node/log4js-node#700

这个是 log4js的问题。
pinus-logger只是对 log4js的一层简单封装。

from pinus.

那有没有什么办法可以解决这个问题呢

from pinus.

对 log4js不太了解。 抱歉帮不上忙。
我用的是 @mybios 给我的精简版配置，不写日志文件的。

可以给你参考一下

好的 谢谢

老哥，这个报错说的是对一个eventEmitter的监听超出默认限制。这个情况出现的原因是有不停的为同一个Event添加监听的情况。
你看看有没有执行的过程中会导致这个情况出现的？这个应该是由于某个逻辑出错后尝试重新加载的逻辑里有添加事件监听导致的

示例项目 已经对 log4js.json的配置做了修复，因为 Log4js的新版本 配置方法不一样。
