报错TypeError: tmpPost.categories.join is not a function

你打开文件 D:\hexo\blog\node_modules\hexo-auto-category\lib\logic.js

加一行代码测试看看呢？

        // 3.2 prevents duplicate file changes
        log.i(tmpPost.categories);   // 添加这一行，打印看看
        if (tmpPost.categories && (tmpPost.categories.join("_") == newCategories.join("_"))) return data;
        tmpPost.categories = newCategories

除了之前的报错,还打印出了我的一些博文的文件夹信息.我是每个文件夹下有一些博文,为啥有的文件夹打印好多次?

看不出来什么原因，再打印一下 type呢？

log.i(typeof(tmpPost.categories));
log.i(tmpPost.categories);  

[vio1etus]

嗯,打印之后是:

是不是因为出现了一个string类型
INFO string INFO hexo
哪来的呢，

谢谢大神, 成功解决. 我把对应那个 hexo 文件夹下的博文的原来自己写的 categories 删除掉,就好了耶. 我看好像是我那里的 categories 格式不太对, 所以报错了. 谢谢
