尝试安装PEAR邮件包，以便我可以在php中发送电子邮件，但我一直收到错误

I go into My cmd prompt and use this command: pear install --alldeps Mail,

but I keep getting this:

C:\xampp\php>pear install --alldeps Mail WARNING: "pear/Auth_SASL" is deprecated in favor of "pear/Auth_SASL2" downloading Mail-1.4.1.tgz ...
Starting to download Mail-1.4.1.tgz (21,756 bytes) ........done: 21,756 bytes downloading Net_SMTP-1.8.0.tgz ...

ERROR: failed to mkdir C:\php\pear\docs\Mail
ERROR: failed to mkdir C:\php\pear\docs\Net_Socket
ERROR: failed to mkdir C:\php\pear\docs\Net_SMTP\docs

and I am still unable to use the mail package I don't know if Im doing this incorrectly or not? How do I install the Pear mail package.

I guess it's a permission problem. Are you able to manually create those directories? If not, you need to do it as admin.
