Package doesn't work: Error in loadNamespace(x) : there is no package named ‘jsonlite’

When I try font_add_google(name = "Noto Sans", family = "Noto Sans") then the error Error in loadNamespace(x) : there is no package named ‘jsonlite’ occurs.

I cannot use the showtext package.

How can I fix this?

As the error message shows, to use font_add_google() you need to install the jsonlite package.

Ok, thank you. I needed to install curl as well. I don't know why these packages were not installed as dependencies (to ensure working functions) automatically.

They are listed as Suggests of the package, since the basic functions of showtext do not rely on them.
