上面的解決辦法是將組件下載後放入pear的目錄，直接對下載的文件進行安裝
http://pear.php.net/package/Structures_Graph/download
下載Structures_Graph-1.0.4.tgz 的 Structures到pear目錄下如：d:/php/pear
然後運行 pear install Structures_Graph 安裝安裝更新
可將下載的Mail-1.2.0.tgz、Net_SMTP-1.4.2.tgz、Net_Socket-1.0.9.tgz拷貝到pear目錄
然後使用peat install Net_Socket-1.0.9.tgz進行安裝即可。安裝成功後使用pear list可看見
