這個例子顯示了類別/介面之間所有可能的鏈接，如metauml第9頁所述文件

除一個連結外，所有連結均正確顯示。這就是「實現」。該連結不會出現。

現在看起來像這樣：

類別

如何解決？

我使用 MetaPost，版本 1.504 (MiKTeX 2.9)

這是我編譯egreg的解決方案時得到的結果：

在此輸入影像描述

這裡您可以從 Metapost 找到嘗試產生實作連結的日誌。

編輯：

我發現我的版本早於 0.2.4，因為該文件C:\Program Files (x86)\MiKTeX 2.9\metapost\generic\metauml\metauml_class_relations.mp不包含realization. 0.2.4 中新增了實作支援。

我只做了一件事。我下載了最新版本並替換了C:\Program Files (x86)\MiKTeX 2.9\metapost\generic\metauml.這就造成了一個「小」麻煩。
日誌 ( tmp+mp000X.log) 表示：

! I can't open file `metauml_component'.
l.77 input metauml_component
                            ;
Please type another input file name
! Emergency stop.
l.77 input metauml_component
                            ;
*** (job aborted, file error in nonstop mode)

我檢查並提到文件確實存在。接下來我該做什麼？

這是輸入 Metapost 片段的正確方法：

Class.B("Class")
       ()
       ();       
A.w = B.e + (50, 0);
drawObjects(A, B);
clink(association)(B, A);
\end{mpost}

\begin{mpost}[use,mpsettings={input metauml;}]

我省略了無關緊要的字幕和figure環境。這就是結果。

在此輸入影像描述

檢查 MetaUML 包的版本。在 0.2.5 版本中它可以工作：參見

<texroot>/doc/metapost/metauml/README

用於檢查版本號。使用套件管理器（MiKTeX 或tlmgrTeX Live）進行更新。
