正如标题所述，externalize 选项会导致一些我无法理解的奇怪错误。它适用于某些图形（例如，我在 pgfplots 手册中找到的代码的图形），但对于使用 matlab2tikz 生成的其他一些图形，如果激活了 externalize 选项，我会收到一些奇怪的错误。
例如如果我的文档看起来像
\documentclass[12pt]{standalone}

\usetikzlibrary{external}
\tikzexternalize[prefix=figures/]

我收到错误，表明我忘记了某个}地方。
但是，如果我注释掉外部化的两行，它就可以正常工作，因此图形代码没有任何问题。
直到最近我才遇到过这个问题，但我真的不知道是什么引发了这个问题。我安装了 pgfplots 和 tikz 的最新版本（不稳定），但这之前没有引起任何问题。最近的变化是我尝试安装字体MinionPro，但我看不出这有什么关系？
我可以找到遇到编译错误的日志这里
昨晚我也尝试安装新 TL 的预测试，但情况仍然一样。有什么建议吗？
答案1
该问题是由于您使用了不稳定的 TikZ 开发版本而引起的。
在撰写本文时，texample.net 上的 PGF 版本包含外部库中的错误（3 天后已修复）。您的问题几乎肯定是由这些更改引起的。您需要至少 5 月 22 日的构建日期才能修复错误。
