`save_kable` and `as_image` generating `PHANTOM ERROR: TypeError: undefined is not a constructor`

[daaronr]

Describe the bug When I use save_kable and as_image it yields PHANTOM ERROR: TypeError: undefined is not a constructor

I am struggling to get webshot to work in general although webshot2 works in isolation.

I get into this in the SO post here

If there were a way to have kable_Extra swap webshot2 in for webshot this might fix it. I think webshot might not be compatible with some systems?

To Reproduce Think about using reprex to generate an example in R.

library(dplyr) 
library(kableExtra)

install.packages("magick")
install.packages("webshot")
webshot::install_phantomjs(force=TRUE)

library(magick)
library(webshot)

mtcars %>% as_tibble() %>%
  janitor::tabyl(cyl) %>%
  kable(caption="don't forget a caption") %>%
  kable_styling() %>% 
save_kable("testmtcarsimage.png")

I'm `fs` modules
PHANTOM ERROR: TypeError: undefined is not a constructor (evaluating 'require('fs').pathJoin(phantom.casperPath, 'modules', 'clientutils.js')')

I just realized this is a partial duplicate of https://github.com/haozhu233/kableExtra/issues/618, although I go into the nature of the bug I'm having a bit more

[Nesh45]

reinstall and installing the kableExtra library will resolve the issue

[Nesh45]

I had the same issue and resolved it by reinstalling the package my code data[anomalies,]%>% kbl(caption ="Anomalies",booktabs =T,align ="l")%>% kable_classic(lightable_options ="striped",html_font ="Arial")%>% save_kable(file = 'tableX.png',bs_theme = "flatly")

I believe this is now fixed in the dev version on GitHub: https://github.com/haozhu233/kableExtra/pull/768
