Thanks for this. It was caused by ...length() being a base function that seems to have been added only in R 3.5.0, but I wrongly said that Librarian would be happy with R => 3.4.0. I've changed the dependency to R 3.5.0.

However, I understand that updating your R installation creates a bunch of headaches with updating all of your packages and then dealing with any API-breaking changes they introduced, so even though librarian needs 3.5.0, I've added a dependency for backports to fix this particular missing function problem so that you can continue using librarian in R 3.4.3.

Just install librarian from GitHub

install.packages("devtools")
devtools::install_github("DesiQuintans/librarian")

and you should be okay!

Now I get this error:

Ah geez, okay I've reverted the R version change.
