因为需要安装phpunit,要先装pear，网上的教程大多数是以双击go-pear.bat开始，但是我安装的php文件夹里压根没有这个文件。经过几次搜索之后终于找到了办法。解决步骤如下:1.下载下面连接的文件go-pear.phar。放到PHP的安装文件下（D:\www\php54)http://pear.php.net/go-pear.phar2.执行php go-pear.phar（Windows上执行的时候因为有UAC的问题所以需要以管理员权限运行CMD。XP下以管理员权限运行CMD的方法：在C:/systerm32文件夹下，右键cmd，运行方式》选择管理员运行）打开cmd，

C:\Documents and Settings\sun>d:

C:\Documents and Settings\sun>cd D:\www\php54 //以此方式进入到 go-pear.phar存放路径

D:\www\php54>php go-pear.phar //安装go-pear.phar
