Blogdown fails rendering a tikz block in my Rmd document - r

Question

This question is very closely related to this question, however the following differences apply:
OS: Unix CentOS in Docker container (image is centos) with Windows host.
Error: Conceptually the same error, but the fix that worked on Windows does not work here and the error message is also different.
I have created a project by using template Hugo-Xmin. In RStudio, after creating the project in blogdown, it created some predefined posts, I am editing this one:
/content/post/2015-07-23-r-rmarkdown.Rmd
I modified that file by adding this snippet at the end of the file:
This is a tikz picture:
```{r, echo=FALSE, engine='tikz', out.width='90%', fig.ext=if (knitr:::is_latex_output()) 'pdf' else 'png', fig.cap='Some caption.'}
\begin{tikzpicture}[scale=.7]
\draw [fill=gray!30,very thick] (0,-1) rectangle (5,1);
\draw [very thick] (5, 0) -- (13,0);
\node [below] at (2,-1) {\large Hello};
\node [below, align=center] at (0,-1) {\large Two\\ lines};
\end{tikzpicture}
```
Failed to process the post
My working directory is the project folder, I run from there, in the R console, the command:
blogdown::build_site()
And get this:
> blogdown::build_site()

running: bash -c "cd ../..;
find . -not -path '*/exampleSite/*' \\( -name '*.html' -o -name '*.css' \\) | xargs wc -l"

Important Please notice that I have followed the help link and added, at the beginning of the file, this snippet:
```{r, include=FALSE}
options(tinytex.verbose = TRUE)
```
The output I reported above, is the output I get when this snippet is in place.
Troubleshooting 1
By inspecting file tikz2b145b766cfa.log (as reported in the error message), I can see the following error:

It is important to know I have installed on the CentOS system a lot of packages and software:
yum install texlive*
And:
install.packages("devtools")
remotes::install_github('yihui/knitr')
install.packages(c('magick', 'pdftools'))
In R.
Troubleshooting 2
As advised, I installed: tinytex. It succeeded. After that, after running build_site(), I always got prompted for a missing library I had to install. After 30 minutes, I got this message:
> blogdown::build_site()
Rendering content/_index.Rmarkdown
running: bash -c "cd ../..;
find . -not -path '*/exampleSite/*' \\( -name '*.html' -o -name '*.css' \\) | xargs wc -l"

hugo: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by hugo)
This one I am struggling with unfortunately as libstdc++-4.8.5-36.el7.x86_64 is already installed and I am not sure how to fix GLIBCXX_3.4.20 and GLIBCXX_3.4.21. Trying yum install on them does not work.

Answer 1

I don't know why your TeX Live could not find preview.sty, but I'm pretty sure TinyTeX will work automatically:
# first make sure all your R packages are up-to-date, then
tinytex::install_tinytex()
