Texlive 2015 问题 - 找不到“article.cls”

Question

编辑：由于忘记在 Texpad 编辑器首选项中更新分布，所以出现了问题！

我刚刚使用昨天下载并安装的 Yosemite 上的完整 MacTeX-2015 发行版将 TexLive 2014 更新到 2015。使用 pdflatex 编译一个简单的新文档后

\documentclass[11pt]{article}

\begin{document}
Test
\end{document}

我收到一条错误消息：

/usr/texbin/pdflatex -file-line-error -interaction=nonstopmode -synctex=1 -output-directory=/Users/xyz/    Desktop/.texpadtmp test.tex

This is pdfTeX, Version 3.14159265-2.6-1.40.16 (TeX Live 2015) (preloaded format=pdflatex)

不用说，文件 article.cls 位于

/usr/local/texlive/2015/texmf-dist/tex/latex/base/article.cls

我努力了

sudo -H mktexlsr

结果对我来说看起来不错：

mktexlsr: Updating /usr/local/texlive/2015/texmf-config/ls-R... 
mktexlsr: Updating /usr/local/texlive/2015/texmf-dist/ls-R... 
mktexlsr: Updating /usr/local/texlive/2015/texmf-var/ls-R... 
mktexlsr: Updating /usr/local/texlive/texmf-local/ls-R... 
mktexlsr: Done.

以及输出

kpsepath tex | sed 's/:/\n/g'

据我所知看起来也不错：

当我切换回 2014 发行版时一切似乎都运行正常......

我很茫然——任何想法都将不胜感激！
