blogdown problem with serve_site() / hugo version

Hi Rstudio,
I am trying to make a new blogdown site using the Hugo Academic theme and running into problems with the version of hugo that I have running. I've updated hugo so that when I do hugo_version() it tells me I have the most recent (0.55.6), but initially when I tried to serve_site, I got an error where it seems like i have two versions of hugo.

I uninstalled hugo using brew uninstall hugo --force, restarted R and did serve site again, and ended up with a different error

I looked at that google link and it is something about the "extended" version of hugo, so I reinstalled hugo with extended = TRUE, but then I ended up with two versions of hugo again.

FYI When I run...

> blogdown:::find_hugo()
[1] "/Users/jenny/Library/Application Support/Hugo/hugo"
> blogdown::hugo_version()
[1] ‘0.55.6’


Hi Jenny,

This is indeed an odd error and you found the extended Hugo thing. When you say you reinstalled hugo, did you use something like this?

blogdown::install_hugo = function(
  version = 'latest', force = TRUE, extended = TRUE

Can you try this solution?


unlink('~/Library/Application Support/Hugo', recursive = TRUE)
blogdown::install_hugo(force=TRUE, extended=TRUE)

Then restart your R session.
