Unable to update Hugo within RStudio Blogdown

I’m using RStudio v1.2.616 (R: v3.4.4) on macOS (High Sierra) with Hugo using the Blogdown R package.

When I check the version, it says I’m at 0.30

> blogdown::hugo_version()
[1] ‘0.30’

I update it using blogdown and then repeat the above to see the same message!

> blogdown::update_hugo()
The latest Hugo version is 0.46
Already up-to-date.

I need a minimum of 0.38 to generate my Hugo website blogdown::build_site()
Any suggestions? Thanks!

This seems to be an issue with blogdown and how it implements update_hugo/hugo_version.
