Try to compile an Rmd document that requires an extra LaTeX package

[yihui]

See if we can figure out that the animate package could be identified in this case.

[AppVeyorBot]

If the message below is truncated, see https://ci.appveyor.com/project/yihui/latex-pass/builds/35445971 for the full version.

Additional packages required to compile your documents are:

animate grfext media9 oberdiek ocgx2 zref

If you are an R user using TinyTeX, you may install these packages via:

tinytex::tlmgr_install(c('animate', 'grfext', 'media9', 'oberdiek', 'ocgx2', 'zref'))

If you use TinyTeX but are not an R user, you may install these packages via command line:

tlmgr install animate grfext media9 oberdiek ocgx2 zref

If you do not use TinyTeX (https://yihui.org/tinytex/), you need to figure out how to install them by yourself.
