git push origin master

当我把远程仓库更新完成的时候, 过了好久发现博客并没有变化. 于是去看了一下Pipelines中的执行过程, 果然报错.

问题1: Error: spawn pandoc ENOENT

这个问题的原因是, 由于需要让Hexo支持数学公式渲染, 所以我在本地使用hexo-renderer-pandoc替换了hexo默认的markdown渲染引擎. 而在.gitlab-ci.yml中没有添加且我本地安装了pandoc, 而gitlab-ci里面没有安装. 以下是我的.gitlab-ci.yml配置,第一个是之前的配置, 第二个是修改之后的配置. 配置1

经过这样修改之后,出现了第二个问题.

问题2: pandoc exited with code 9: pandoc: Unknown extension: smart

FATAL Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html
Error: pandoc exited with code 9: pandoc: Unknown extension: smart

出现这个问题的原因是, pandoc从2.0版本之后, 取消了smart这个扩展, 说白了也就是gitlab-ci中安装的pandoc版本太低. 于是我们只要更换一个2.0版本以上的pandoc即可解决.

对应的.gitlab-ci.yml配置如下:
