The error message "! LaTeX Error: File `standalone.cls' not found" indicates that the LaTeX package "standalone" is missing.
Should be a part of the texlive-latex-extra package, so maybe that whole thing is missing?

I setup webwork from https://webwork.maa.org/wiki/Installation_Manual_for_2.16_on_RHEL8.
In "RHEL Software Packages" in the installation document, it said "# yum -y install dvipng gd-devel texlive-latex httpd-devel mysql-server mysql-devel netpbm-progs ImageMagick dvisvgm nodejs"
so I installed that.

Now, I am trying to install standalone in rhel 8. However, In rhel 8, there is no list for texlive-latex-extra. Could you help me find alternative for texlive-latex-extra?

Hopefully someone using redhat can help you. I could not even install webwork under redhat, currently using ubuntu.

There is also an option to use texlive's package manager "tlmgr" to install LaTeX packages.
