主干是3.x版的，nodeclude用的是2.x版，一定要安装2.x版，要不会出很多错。
好久的问题了 今天我也碰到了 参数必须是对象或者字符串 把数据库查询函数find中的 [fields] <Object> optional fields to select 参数 改了就好吧 好像是老版本的是 ['xxx','xxxxx','xxxxxxx'] 这种形式的
我也遇到同样的问题,lz解决了没?
解决了,是因为find()这个方法调用错误,错误总共有3出,1处在tag.js,1处在topic.js,1处在user.js,把多余的参数去除就可以了
请具体之处那几处错误好吗？？

这个问题我已经解决了、、、、、、 但是又有一个错误。。。。
错误是这样的：

请问是什么意思呢？ 是我的依赖包 版本问题嘛？？
有可能是版本问题
问题是由于传入参数为空值引起的,查找select()方法,把空值去掉就可以了
文件都在F:\node AND android\mblog\controllers这个文件夹下
