[b]安装环境 [/b]　　在安装PEAR之前需要配置安装PHP环境，如果没有自带PEAR (直接访问http://go-pear.org并保存其首页为go-pear.php) [b]PEAR安装准备[/b] 　　如果PHP运行环境没有自带PEAR，则需要下载go-pear.php文件，同时保存在php.exe所在的目录下。 [b]PEAR安装步骤 [/b] 1、我这里用的是wamp集成环境，d:\wamp\bin\php\php5.2.5>go-pear，开始自动安装。 [img]http://files.jb51.net/upload/201105/20110522194432479.jpg[/img] 通过这个PEAR安装截图，可以看到首先需要确认PEAR的安装目录结构，系统通常能自动识别。 2、确认好PEAR在Windows下的安装目录结构，回车，开始下载和安装PEAR的默认扩展包，你也可以选择是否同时安装Pear_Frontend_Web-beta，Pear_Frontend_Gtk2，MDB2扩展包。 [img]http://files.jb51.net/upload/201105/20110522194445350.jpg[/img] 3、PEAR默认扩展包安装后，提示是否需要配置php.ini文件中的include_path选项指向pear的安装目录，当然需要配置，否则无法使用，Y并回车，安装包会自动修改include_path选项。 [img]http://files.jb51.net/upload/201105/20110522194519251.jpg[/img] PEAR安装完成，双击PEAR_ENV.reg将相关信息导入注册表，同时重启Apache即可。 [b]PEAR的其他安装方法[/b] 　　如果PHP运行环境自带PEAR，则可以在PHP目录下找到PEAR.DAT文件，双击这个文件即可进行PEAR安装，方式应该类似上述安装方式。同时注意修改PHP.INI中的include_path选项即可。 [b]PEAR命令[/b] 　　在命令行方式下，运用PEAR的相关命令可以安装自己需要的PEAR安装包。 　　pear help  列出pear的所有命令，类似于pear的命令帮助命令。 　　pear help <command>  列出某个pear命令的具体信息 　　pear help shortcuts  列出所有pear命令的简写 　　pear list-all  列出所有可安装的packages，很多，可以访问[url=http://pear.php.net/packages.php]pear扩展包列表[/url]找到需要的packages，再使用pear install命令安装package。 (安装pear时，可以让其使用默认值，一直回车完。) 　 [b]接着安装单元测试框架phpunit:[/b] [u]d:\wamp\bin\php\php5.2.5>pear channel-discover pear.phpunit.de[/u] Adding Channel "pear.phpunit.de" succeeded Discovery of channel "pear.phpunit.de" succeeded [u]d:\wamp\bin\php\php5.2.5>pear install phpunit/PHPUnit[/u] Did not download optional dependencies: pear/Image_GraphViz, pear/Log, channel:/ /pear.symfony-project.com/YAML, use --alldeps to download automatically phpunit/PHPUnit requires PEAR Installer (version >= 1.8.1), installed version is  1.6.1 phpunit/PHPUnit can optionally use package "pear/Image_GraphViz" (version >= 1.2 .1) phpunit/PHPUnit can optionally use package "pear/Log" phpunit/PHPUnit can optionally use package "channel://pear.symfony-project.com/Y AML" (version >= 1.0.2) phpunit/PHPUnit can optionally use PHP extension "pdo_sqlite" phpunit/PHPUnit can optionally use PHP extension "soap" phpunit/PHPUnit can optionally use PHP extension "xdebug" (version >= 2.0.5) No valid packages found install failed (安装phpunit失败，此时通过pear upgrade pear更新pear后继续安装) [u]d:\wamp\bin\php\php5.2.5>pear upgrade pear[/u] downloading PEAR-1.9.0.tgz ...
