I use babel with the russian option, and the error message is that
Font T2A/cmr/m/n/9=larm0900 at 9.0pt not loadable: Metric (TFM) file or installed font not found.
Firstly, I use tlmgr to search for this font, but there is no result. Then I download texlive-lang-cyrillic from Macport, but I cannot find Font T2A/cmr/m/n/9=larm0900 in it.
If anyone has larm0900.tfm, please share it.
As suggested by egreg , I did
sudo tlmgr install collection-langcyrillic and the tex file can be compiled, but the output is just a blank. This is because I used Xelatex, the output is normal when I use Pdflatex.
But is it possbile to use Xelatex and get the normal output?
