我试图安装php扩展OAuth在我的centos 6 linux服务器。 php.net表明这很容易。 你只是跑步
pecl install oauth 我试过了，这里是terminal的输出：
[root@www extensions]# pecl install oauth WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update downloading oauth-1.2.2.tgz ...

Please use --with-php-config=PATH ERROR: `/var/tmp/oauth/configure' failed
有一个错误：
configure: error: Cannot find php-config.
并在同一行上说明如何解决这个问题：
Please use --with-php-config=PATH
显然， PATH需要被replace为你的php-config的实际path。
如果你没有安装php-config ，你必须先安装。
