2. 如果需要扩展，打开php.ini，设置 extension_dir = "ext" , 取消对应扩展的注释
3. 打开cmd，进入php5.x.x目录，运行go-pear
4. 提示

   Are you installing a system-wide PEAR or a local copy?
   (system|local) [system]

   按回车确定

   确定无误，则按回车，输入数字则修改对应项。修改后，按回车进行安装。

6. 生成环境变量PEAR_ENV.reg文件，双击导入注册表
7. 此时，输入pear -V 查看版本信息，输入pear list 查看已安装的包
8. 如果pear list查看没有 Image_GraphViz 包和 Log 包，则使用 pear install Log 安装Log，使用 pear install Image_GraphViz
9. 安装 Image_GraphViz 时，如果提示不能包含Structures/Graph/Node.php，则
   1. 尝试set查看PHP_PEAR_*相关环境变量是否正确
   2. 尝试关闭cmd窗口，再打开，再pear install Image_GraphViz
   3. 尝试pear install Stuctures_Graph，再pear install Image_GraphViz
10. 至此，pear list 应有
