Feature Request

Some themes (e.g. Hive and Overdose) would require additional renderers (e.g. hexo-renderer-sass) or other npm packages (e.g. jquery) during their build, but currently there is no way for a theme to install them except for asking users to install them manually. If Hexo can install the theme dependencies automatically to the site, installing and changing themes will be easier.

Actually, there are two ways to install dependencies:

1. Install theme through npm. All the dependencies of the theme will be installed automatically
2. Use postinstall script in package.json

However, the two themes you mentioned have not been updated for years. You need to contact the maintainer to publish them on npm.
