I installed the basic LaTeX edition for Mac. I used the package manager ttlmgr to install relsize and bbm.

For some reason the package relsize is found but not bbm...

Any idea what goes wrong? (note: I run pdflatex myfile.tex in the screenshot)

Another thing I noted: I actually created by hand bbm/bbm.sty (downloaded) because it didn't exist. There were


though, but things didn't work before or after adding this. And weirdly it doesn't "find the package" but there is a bbm.sty file... I'm confused

  • You seem to have installed BasicTeX, which only include a few packages. You need to use TeX Live Utility to install also bbm (but I'm not sure you want to use it, as it only provides bitmap fonts). – egreg May 18 at 23:01
  • @egreg but what is the standard way to install something / why does tlmgr not work? Also it seems I have /Library/TeX (and probably lots of symlinks there) so should I try to install "by hand" the bbm.sty file there? – Thomas May 18 at 23:05
  • If you can run either LuaLaTeX or XeLaTeX, you might want to use unicode-math, which supports double-struck symbols. If not, you might want to use one of the options from mathalfa, or dsfont. – Davislor May 19 at 1:19
