Sphinx 错误 ‘md‘ \u7684 source_parser \u5df2\u6ce8\u518c

今天用read the docs的时候出现了下面的错误：

Extension error:
'md' \u7684 source_parser \u5df2\u6ce8\u518c
Command exited with exit code: 2
The server will continue serving the build folder, but the contents being served are no longer in sync

解决方法

pip install

升级一下Sphinx就行了，我原来的Sphinx是2.1.2版本，我现在升级到3.5.4就可以了哈。
