我的 MacBook Pro 上安装了 TeX Live，运行MacOSX 10.8的是macports。最近，当我尝试编译 LaTeX 文件时，pdflatex出现了错误
/opt/local/share/texmf-texlive/tex/generic/hyph-utf8/patterns/tex/hyph-fr.tex)
)

Please type another input file name:
! Emergency stop.
<to be read ' instead of a filename.
I can't find the format file `pdflatex.fmt'!
经过一些谷歌搜索后，我发现也许sudo fmtutil-sys --all可以解决这个问题，但最终出现了以下错误：
This is a summary of all `failed' messages:
`pdftex -ini -jobname=pdftex -progname=pdftex -translate-file=cp227.tcx *pdfetex.ini' failed

关于我可以在这里做什么有什么线索吗？

我今天遇到了同样的问题（这里是 OS X 10.6 和 MacPorts。）对我有用的解决方案是执行sudo port install texlive-lang-german。

当你安装了 TeX 后，不要按照系统提示设置环境。只需设置这一个即可。
#TEXMFSYSVAR=/usr/local/texlive/2013/texmf-var
你 # 它，然后重新登录。 就好了！
