我使用 MacTex 2015 和 Texpad 作为 LaTeX 编辑器。当我尝试导入 tzik 包时
\usepackage{tikz}
出现以下3个错误
但奇怪的是，我的文档中的一切看起来都很好。
我的所有软件包也都是最新的。我是否必须导入其他软件包？有人遇到过同样的问题吗？

答案1
您的 TikZ 图像代码有错误：您使用\draw [-latex] (4) -> (5);而不是\draw [-latex] (4) -- (5);。还缺少 TikZ 库arrow。除此之外，请查看下一个图像代码是否对您有用：
\begin{tikzpicture}[
node distance = 21mm and 11mm,
start chain = going right,
place/.style = {rectangle, draw, thick, minimum size=6mm,
on chain}
]
\node[place] (4) {Shrinked Dataset};
\node[place] (5) {Weighting Features};
\node[place] (1) {SVM Classifier};
\node[place] (2) {Model};
%
\node[place] (3) [below=of 1] {Performances (fitness) Evaluation};
%
\draw[-latex] (4) edge (5)
(5) edge (1)
(1) edge (2)
(2) edge (3);
\draw[-latex] (3) -- node[fill=white] {$p_i$} (5);
\draw[-latex] (3) -- node[fill=white] {$C$ and $\gamma$} (1);
\end{tikzpicture}
它需要 Tikz 库chains和positioning，即在序言中你需要添加\usetikzlibrary{arrows,chains,positioning}。上面的代码给出：
