I am running jupyterlabs on docker and wanted to install the rvg package. One of the dependencies are systemfonts, and when I tried to install this using install.packages("systemfonts") I get:
Warning: unable to access index for repository https://cran.yu.ac.kr/src/contrib:
cannot open URL 'https://cran.yu.ac.kr/src/contrib/PACKAGES'
Warning message:
package ‘systemfonts’ is not available for this version of R
A version of this package for your version of R might be available elsewhere,
see the ideas at
https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages
So I downloaded the tar.gz file from CRAN and installed from file, but I get a fatal error:
> install.packages("systemfonts_1.0.2.tar.gz", repo = NULL, type = "source")

I tried to follow this SO Post, by typing in sudo apt-get install -y libfreetype6 to get freetype, but it is already the newest version. I'm not sure what else to try, hopefully someone can provide some expertise. Thanks.
Searching for "ft2build.h: No such file or directory Ubuntu" leads to this issue on systemfonts library GitHub where a workaround for the compilation error for Ubuntu 20.04 is shown:
sudo apt-get update
sudo apt-get install libfontconfig1-dev
This should help you to compile library from the tar.gz source.
