Errors When Running README Example

[realauggieheschmeyer]

Hello! I'm running into two different errors when trying to run the example code from the README.

The first of these is that when I try to run remotes::install_github("mitchelloharawild/fable.prophet") I get a message that prophet is not available. I wonder if this has anything to do with prophet being temporarily unavailable on CRAN.

The second issue I run into is that tsibbledata::aus_retail is being detected as "a corrupt tsibble object."

Any thoughts on what I can do to remedy these issues? Please and thank you.

Yes, the installation issue is due to prophet not being on CRAN.
Regarding the tsibbledata issue, you are likely using the dev version of tsibble and the cran version of tsibbledata (or vice-versa). I recommend using the CRAN versions of both these packages unless you need dev versions for some specific reason.
