I'm using the bslib package Version: 0.6.1 with R version 4.3.2. When I use the line
bs_theme(bootswatch ="darkly", version = 4)
I get the error:
Warning: Error in component_dependency_sass_: bslib components require Bootstrap 5 or higher.
I am not yet ready to move to boostrap 5 and need to deploy using bootstrap 4. Is this still possible at all, or must I revert to using an older version of R to do this?
