\path 命令存在问题，未定义控制序列

Question

我正在尝试创建一个逻辑方案，但\path环境命令有问题tikzpicture。我不知道为什么，但我无法在节点之间创建连接。我尝试了各种命令（\path、、、等），但编译时 LateX 说它是一个。请参阅下面的代码。\path{draw}\draw\path[->]Undefined control sequence

如果我用代码注释这些行，则\path...可以正常工作，但显然这些框没有任何箭头链接。

我究竟做错了什么？

PS：我使用的是 Win7，MikTeX 2.9 64 位和 TeXnicCenter

原始代码包含一个’（RIGHT SINGLE QUOTATION MARKUnicode 中的）而不是'（APOSTROPHEUnicode 中的）

\tikzstyle{line} = [draw, thick, -latex’,shorten >=0pt];

使用正确的提示，代码可以编译成功：
