如何在 Debian 7.7 上安装 graphviz？

Question

我是编程新手。我刚刚安装了我的 Debian 并安装了以下软件包

dpkg -l | grep graph
ii  graphviz                           2.26.3-14+deb7u2              amd64        rich set of graph drawing tools
ii  libart-2.0-2:amd64                 2.3.21-2                      amd64        Library of functions for 2D graphics - runtime files
ii  libcairo2:amd64                    1.12.2-3                      amd64        The Cairo 2D vector graphics library
ii  libcdt4                            2.26.3-14+deb7u2              amd64        rich set of graph drawing tools - cdt library
ii  libcgraph5                         2.26.3-14+deb7u2              amd64        rich set of graph drawing tools - cgraph library
ii  libgraph4                          2.26.3-14+deb7u2              amd64        rich set of graph drawing tools - graph library
ii  libgraphviz-dev                    2.26.3-14+deb7u2              amd64        graphviz libs and headers against which to build applications
ii  libgvc5                            2.26.3-14+deb7u2              amd64        rich set of graph drawing tools - gvc library
ii  libgvpr1                           2.26.3-14+deb7u2              amd64        rich set of graph drawing tools - gvpr library
ii  libpathplan4                       2.26.3-14+deb7u2              amd64        rich set of graph drawing tools - pathplan library
ii  libxdot4                           2.26.3-14+deb7u2              amd64        rich set of graph drawing tools - xdot library
ii  openssl                            1.0.1e-2+deb7u12              amd64        Secure Socket Layer (SSL) binary and related cryptographic tools

我还使用了以下程序来启动 Graphviz：

<?php
require_once 'Image/GraphViz.php';

$gv = new Image_GraphViz();
$gv->addEdge(array('wake up'        => 'visit bathroom'));
$gv->addEdge(array('visit bathroom' => 'make coffee'));
$gv->image();
?>

但我得到的是：

addEdge(array('wake up' => 'visit bathroom')); $gv->addEdge(array('visit bathroom' => 'make coffee')); $gv->image(); ?>

请告诉我如何处理这个问题？

此致

您需要为 GraphViz 安装 PHP 绑定。我没有 Debian 镜像来尝试这个，但是试试：

sudo apt-get install libgv-php5

如果这不起作用，请尝试：

sudo apt-cache search libgv | grep -i php

更新：上面给出的代码在执行以下命令后适用于干净的 Debian 7 映像：

sudo apt-get update
sudo apt-get install apache2 libapache2-mod-php5 libgv-php5 graphviz vim php-pear
sudo pear install Image_GraphViz

# Copy the file above to test.php
php5 test.php
