我的合著者给我发了一个需要 tikz 的 latex 文件。我发现 LaTeX 在加载 tikz 时卡住了。我使用的是新安装的 texlive2012 安装（但我检查了 TeX Live 2011 和 2010 上也发生了同样的事情）。
测试文件：
\documentclass[11pt,reqno]{amsart}
\usepackage{tikz}
\begin{document}
blah
\end{document}
错误：

正如我所料，演示对我来说运行良好。您的问题由以下行显示
(/Users/fgoodman/Library/texmf/tex/latex/pgf/pgf.sty
在日志文件中。您有一个当地的的副本pgf.sty，可能是旧副本，将优先于/usr/local/texlive/2012（或其他年份，视情况而定）的“系统范围”副本加载。尝试将旧文件移出~/Library/texmf：实际上，您可能还有其他旧文件，因此请仔细检查您的日志。
