昨天写博客的时候，一套hexo操作行云流水，奈何一个hexo g报错报了几百行，在终端里的错误让人害怕的发抖，先上图为敬。
一个空格引发的bug

显然这些带有具体文件路径和出错位置的error很难直接百度到解决方法，在百度了很久之后，我找到一个貌似跟我的bug相关的关键词： YAMLException

这是一个在yaml文件中的报错。

于是怀着一个科班出身的计算机人的心态，我决定自己读报错改bug。

  • 首先找到加载出错的原因：
    ERROR Theme config load failed.
    这大概是主题配置文件加载失败了？？？

  • 其次是出错的文件：
    ERROR Process failed: _config.yml
    果然是主题配置文件出错了！

  • 继续找一下出错原因：

妈耶，一开始看到这些bug我已经准备放弃了，因为这些bug并没有影响我提交博客的相关操作。

但是每次 hexo g 后总跟着几百行报错我看起来很难受啊。

还是继续冷静的分析一下吧。

  • 找到YAMLException的提示位置，第823行。
    Alt text

所以，原来是我多打了一个空格！

  • 好了，冷静地把空格删掉。
    Alt text

  • 重来一遍hexo g，完美运行～
    Alt text

这个案例告诉我们，修改文件的时候不要把空格不当回事儿，不然都是bug劝退。

小手一抖⬇️
