我已经安装了tinytex，现在我试图将.rmd编织为.pdf，但是我发现自己收到了以下消息：
output file: *_report.knit.md
tlmgr search --file --global "/multirow.sty"
Trying to automatically install missing LaTeX packages...
tlmgr install multirow
No connection to the internet.
Unable to download the checksum of the remote TeX Live database,
but found a local copy so using that.
You may want to try specifying an explicit or different CTAN mirror;
see the information and examples for the -repository option at
http://tug.org/texlive/doc/install-tl.html
(or in the output of install-tl --help).

我想我做错了什么，或者我错过了一些代码，但是环顾四周之后，我承认失败了， 任何帮助非常感谢 谢谢，
