此问题与this question密切相关，但是存在以下差异：
centos）中的Unix CentOS。我已经使用模板Hugo-Xmin创建了一个项目。在RStudio中，在Blogdown中创建项目后，它创建了一些预定义的帖子，我正在编辑此帖子：
import os
from django.core.wsgi import get_wsgi_application
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myapp.settings')
application = get_wsgi_application()
我通过在文件末尾添加以下代码段来修改了该文件：
/content/post/2015-07-23-r-rmarkdown.Rmd
我的工作目录是项目文件夹，我从那里运行，在R控制台中，命令：
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}
```
并得到这个：
blogdown::build_site()
重要：请注意，我已遵循帮助链接，并在文件开头添加了以下代码段：
> blogdown::build_site()

通过检查文件```{r, include=FALSE}

（如错误消息中所述），我可以看到以下错误：

根据建议，我安装了：install.packages("devtools")
remotes::install_github('yihui/knitr')
install.packages(c('magick', 'pdftools'))
。成功了。之后，在运行tinytex之后，总是提示我缺少必须安装的库。 30分钟后，我收到此消息：

答案 0 :(得分：1)
我不知道为什么您的TeX Live无法找到preview.sty，但是我很确定TinyTeX会自动运行：
# first make sure all your R packages are up-to-date, then
tinytex::install_tinytex()
