我想在我的Windows 7上安装pear，但是我收到了错误：
phar "D:\wamp\bin\php\php5.5.12\go-pear.phar"
SHA1 signature could not be verified: broken signature
Warning: require_once(phar://go-pear.phar/index.php): failed to open stream: phar "D:\wamp\bin\php\php5.5.12\go-pear.phar" SHA1 signature could not be verified: broken signature in D:\wamp\bin\php\php5.5.12\go-pear.phar on line 1236
Call Stack:
0.0270 524984 1. {main}() D:\wamp\bin\php\php5.5.12\go-pear.phar:0**
我将php.ini配置为：
phar.require_hash = Off
我找不到解决这个问题的方法。
