hexo-error

My personal blog uses Hexo, which is simple but can still encounter some minor issues. Here are some common errors.

YAMLException: can not read a block mapping entry; a multiline key may not be an implicit key at line 2, column 1

This is essentially a syntax error, for example like this:

Running hexo g will report the above error because of the [] brackets, so you need to add single quotes '':

Run it again and it should work.

Final Thoughts

Hexo is a powerful static site generator, but like any tool, it can encounter syntax and configuration issues. Understanding common YAML errors and their solutions can save time and frustration when working with Hexo. Always remember to properly quote special characters in YAML frontmatter to avoid parsing errors.
