为什么 $pear->packageExists() 在安装的包上总是返回 false?

问题描述

我安装了邮件 (http://pear.php.net/package/Mail)通过

I installed Mail (http://pear.php.net/package/Mail) by

pear install Mail

似乎一切正常，但以编程方式检查此包:

everything seems to be ok, but checking for this package programmatically:

$pear = new PEAR_Registry();
$enabled = $pear->packageExists('Mail');

对我来说总是失败(错误).

always fails for me (false).

有人能给我任何建议吗?

Could someone give me any advice?

如果我再次尝试安装 Mail，我会得到:

If I try to install Mail once again, I am getting:

pear/Mail is already installed and is the same as the released version 1.2.0
install failed

我的 include_path 设置:

My include_path settings:

include_path = ".;C:\Program Files (x86)\IIS Express\PHP\v5.3\pear;"

邮件包安装到 C:\Program Files (x86)\IIS Express\PHP\v5.3\pear\Mail 目录

Mail package was installed to C:\Program Files (x86)\IIS Express\PHP\v5.3\pear\Mail dir

重新安装邮件没有帮助

推荐答案

我认为您使用了错误的注册表文件.

I think you're using the wrong registry file.

尝试将 PEAR 安装目录作为第一个参数传递给 PEAR_Registry 构造函数.它是 .registry 目录所在的目录，例如/usr/share/php/.

Try to pass the PEAR installation directory as first parameter to the PEAR_Registry constructor. It's the directory in which the .registry directory exists, e.g. /usr/share/php/.
