[R] Webshot failed to take snapshot in Ubuntu machine
Hi,
I was using webshot package to take snapshot of a webpage as below:
library(webshot)
webshot('
https://www.bseindia.com/stock-share-price/asian-paints-ltd/asianpaint/500820/',
'bb.pdf')
However what I see is a Blank PDF file is saved.
However if I use the same code in my windows machine it is able to produce
correct snapshot.
Below is my system information> Sys.info()
sysname
"Linux"
release
"4.4.0-139-generic"
version
"#165-Ubuntu SMP Wed Oct 24 10:58:50 UTC 2018"
nodename
"ubuntu-s-2vcpu-4gb-blr1-01"
machine
"x86_64"
login
"root"
user
"root"
effective_user
"root"
Any idea what went wrong would be highly helpful.
Thanks,

You can install it with webshot::install_phantomjs(). If it is installed, please make sure the phantomjs executable can be found via the PATH variable. NULL So, it is clear this relies on extra javascript based software being available on your computer, *and* having that correctly in your PATH. On my linux system, I then did webshot::install_phantomjs() and that downloaded things and installed a 67 Megabyte executable in my PATH ... which then subsequently worked. On that Linux system it did *not* work, try system("which phantomjs") and you should see that it gets a version of 'phantomjs' on your computer, i.e., the one that webshot() will then try to use and somehow fails. I'd recommend you run webshot::install_phantomjs() which then should install a "better" version of the 'phantomjs' executable that then *should* work .. Let us know if this helped (or why not).
