[Tex/LaTex] Package babel Error: Unknown language `french’ (not ‘francais’)

labelslanguages

I solve the problem Unknown option 'francais' by installing the missing language package:

​sudo apt-get install texlive-lang-european

Now, encounter the problem Unknown language 'french', the detailed error info is as follows:

! Package babel Error: Unknown language `french'. Either you have
(babel)                misspelled its name, it has not been installed,
(babel)                or you requested it in a previous run. Fix its name,
(babel)                install it or just rerun the file, respectively.

Best Answer

The texlive-lang-european is for a bunch of European languages, among which there's not French; do

sudo apt-get install texlive-lang-french

See https://packages.debian.org/stable/tex/texlive-lang-french and https://packages.debian.org/stable/tex/texlive-lang-european for details about the packages.
