Problem with gt::gt_save() in a Ubuntu virtual machine on Azure
I try the following code
The usecase is run the code on virtual machine in Azure, Ubuntu 22.04.
table <- mtcars |>
gt::gt()
gt::gtsave(table,"/home/ubuntu/test.png")
But I recieved this error and the .png file don't saved

In 0.6.0 version this don't happened, and it's happen and started by exchanging the use of webshot for webshot2 At first I received the error message due to the lack of chrome or chromium But after installing, I received this other
Adding information If I just use webshot2 it works normally
webshot2::webshot("https://www.r-project.org",
file = "test.png")
This code work's perfectly
I was rendering reports to MS Word. Using gt version 0.6.0, I could not create tables in Word so I used gtsave() to save an image and import into the Rmarkdown for rendering to Word. After updating to gt version 0.7.0, the markdown document would render the png image in my directory, but it would not import into Rmarkdown and the image was not rerndered in the MS Word document. I have removed version 0.7.0 and reverted to version 0.6.0 and all is working as before.
Just wanted to contribute that my experience this morning confirms this behavior is apparently unrelated to Azure or VM's. My org models Posit's Shared Baseline env arch, we advanced the date and this bug appeared in the version now available to our environment, taking down a cascade of scheduled reports.
That's on Ubuntu 20 LTS bare metal.
Hello This problem still persists here for me, I don't know what to do with it and I haven't found a way to solve it webshot2 works normally on my machine, but I can't use gt > 0.6.0 because it uses webshot2
My problem is in the webshot2 selector parameter
When selector = 'table', it doesn't work, I don't know why yet, I'm also discussing an issue on webshot2's github
https://github.com/rstudio/webshot2/issues/47
Hi @henrique1008, can you re-run your example and then call sessioninfo::session_info() in the test environment? Then copy and paste the results of that function into a code block here. (The reprex package can also do this for you.) That would help us recreate your environment to investigate.
Hi @gadenbuie Thank you for your help
Looking inside the gt::gtsave() function, to save to png it uses a non-exported function called gt:::gt_save_webshot()
The code of gt:::gt_save_webshot() is below:
gt_save_webshot <- function(data, filename, path = NULL, ..., selector = "table",
zoom = 2, expand = 5) {
filename <- gtsave_filename(path = path, filename = filename)
tempfile_ <- tempfile(fileext = ".html")
tempfile_ <- tidy_gsub(tempfile_, "\\\\", "/")
gt_save_html(data = data, filename = tempfile_, path = NULL)
if (!requireNamespace("webshot2", quietly = TRUE)) {
cli::cli_abort(c("The `webshot2` package is required for saving images of gt tables.",
`*` = "It can be installed with `install.packages(\"webshot2\")`."
))
} else {
webshot::webshot(
url = paste0("file:///", tempfile_),
file = filename, selector = selector, zoom = zoom,
expand = expand, ...
)
}
}
I'll reproduce the behavior of the function here
example_table <- mtcars |> gt::gt()
data <- example_table
filename <- "my_table.png"
path = NULL
selector = "table"
zoom = 2
expand = 5
filename <- gt:::gtsave_filename(path = path, filename = filename)
tempfile_ <- tempfile(fileext = ".html")
tempfile_ <- gt:::tidy_gsub(tempfile_, "\\\\", "/")
gt:::gt_save_html(data = data, filename = tempfile_, path = NULL)
webshot2::webshot(
url = paste0("file:///", tempfile_),
file = filename,
selector = selector,
zoom = zoom,
expand = expand,
)
And I get this error
Registered S3 method overwritten by 'webshot2':

print.webshot webshot

2: In normalizePath(value) :

": No such file or directory
But if I try without selector parameter in webshot2, I don´t get this error, however the .png that is saved is blank
To work around I made a fork of the gt package, and replaced webshot2 with webshot, now I'm able to use the latest version of gt

Another workaround (similar to https://github.com/rstudio/gt/issues/97#issuecomment-469751769). Produce html output and then run webshot manually.
library(gt)
library(webshot)
table <- mtcars |>
gt::gt()
gt::gtsave(table,"table.html")
webshot::webshot(url = "table.html", file = "table.png")
Another workaround (similar to #97 (comment)). Produce html output and then run webshot manually.
library(gt) library(webshot) table <- mtcars |> gt::gt() gt::gtsave(table,"table.html") webshot::webshot(url = "table.html", file = "table.png")
This didn't work for me. Well, it does, but now I get a huge screenshot with a ton of whitespace, which is not ideal.
