我已将 texlive 更新至 2012 版。然而,当我尝试编译从以下网址获得的示例代码时,这里,我的尝试失败了。

我已经移除并安装了,3kernel l3packages l3experimental
但这也无济于事。
sudo tlmgr remove --force l3kernel l3packages l3experimental
sudo tlmgr install l3kernel l3packages l3experimental
查看时/usr/local/texlive/2012/texmf-dist/tex/latex/l3packages/xparse/xparse.sty
我注意到它正在寻找expl3
,但尚未安装。请参见下文。

请您给我指出正确的方向,告诉我如何解决这个问题?
