I am running into this warning message that will stop execution.
Saving 8.04 x 5.67 in image
Warning messages:
1: In dev(file = filename, width = dim[1], height = dim[2], ...) :
unable to load shared object '/usr/local/Cellar/r/3.5.0_1/lib/R/library/grDevices/libs//cairo.so':
dlopen(/usr/local/Cellar/r/3.5.0_1/lib/R/library/grDevices/libs//cairo.so, 6): image not found
2: In dev(file = filename, width = dim[1], height = dim[2], ...) :
failed to load cairo DLL
This is the code that generates that warning for me
library(tidyverse)
library(cowplot)
d <- sample_n(diamonds, 50)
g <- ggplot(d, aes(carat, price)) + geom_point()
gg <- list(g,g,g)
plot_grid(plotlist = gg, nrow=1) %>%
cowplot::ggsave(filename = paste0("~/Desktop/", paste0("testing", ".svg")), device = cairo_ps)
How do I go about fixing this error?
P.s. I am a novice.
EDIT: This is my session information. I am not sure if this would be helpful. I have included it just in case.

I only have a Windows machine to offer, but the following worked for both saving a .svg and .eps of your cowplot (after installing the package svglite):
# install.packages(svglite)
library(tidyverse)
library(cowplot)
d <- sample_n(diamonds, 50)
g <- ggplot(d, aes(carat, price)) + geom_point()
gg <- list(g,g,g)
plot_grid(plotlist = gg, nrow=1)
ggsave(filename = "testing.svg")
ggsave(filename = "testing.eps")
You can of course modify the filename to something like "~/Desktop/testing.svg", depending on where you want to safe your plot. Note that ggsave per default saves the last active plot, and the ending of the filename you specify should automatically trigger the right device.
