我正在尝试在 Ubuntu 11.10 上安装的 TexLive 上安装 subcaption 包。当尝试构建 subcaption.sty 时，我发现我需要先下载或构建几个依赖项：
diagbox.sty
epic.sty
footmisc.sty
overpic.sty
pict2e.sty
将这些文件放在与 subcaption.dtx 相同的目录中后，我尝试构建 subcaption.sty，结果如下：

我做错了什么？我该如何解决？
（我是新手...我不知道 dtx、ins 或 sty 文件是什么。我所知道的是，我通常可以运行latex file.ins来生成file.sty，然后放入file.sty适当的目录并使用该包。）
[安装最新版本的 TexLive 后，我遇到了问题...请参阅下面的链接]
答案1
latex subcaption.dtx将要不是构建subcaption.sty，但文档却subcaption.dvi相反。subcaption.pdf包subcaption本身没有不是diagbox.sty对、epic.sty、footmisc.sty、overpic.sty或有依赖关系pict2e.sty，您只需要它们来为自己构建文档。（此步骤不是必需的，因为文档已经预先构建为subcaption.pdf。）
在为自己构建软件包文档时，您会收到错误消息“caption package not loaded”，subcaption因为构建文档需要subcaption安装的软件包的实际版本。因此，您需要先更新caption软件包包（其中包括subcaption.sty）。
latex caption.ins或tex caption.ins将构建所需的包文件，即caption.sty，...和subcaption.sty。但从 CTAN 获取 LaTeX 包的最简单方法是先查找 TDS 结构化档案，它们位于
http://mirrors.ctan.org/install/macros/latex/contrib/
如您所见，有一个 caption.tds.zip，因此获取此文件，解压缩它，然后将其内容放到正确的位置，就是安装/更新整个caption软件包（包括 sty 文件和文档）所需要做的全部工作。
