hexo错误的解决

准备正式开始用hexo写第一篇文章，打开powershell，新建了一个文件，然后用typora开始编辑新建的文件，保存，运行hexo generate，报错：

ERROR Process failed: _posts/一个奇怪的问题.md
YAMLException: can not read a block mapping entry; a multiline key may not be an implicit key at line 4, column 1:

Google之，发现说是_config.yaml格式不对，不能解析，再三检查，看所有冒号后面都有空格啊，甚至找了个原版的来替换掉，还是这个问题，百思不得我姐。

于是删掉这篇文章，运行hexo g，没问题。

又新建一篇文章，然后用typora编辑这个文件的时候，赫然发现头部填写tags的时候，字符是默认紧挨在冒号后面写的，后面少了一个空格。

解决！
