Question

我開發了一個joomla組件。但是在嘗試安裝時出現此錯誤。 「JInstaller ::安裝：找不到Joomla XML安裝文件」

錯誤 路徑沒有有效的包。

下面是myforms.xml文件

 <? xml version = "1.0"encoding = "utf-8" ?> 
    <extension type="component" version="3.2" method="upgrade"> 
    <name>My Forms!</name>

    <update> 
      <schemas> 
        <schemapath type="mysql">sql/updates/mysql/</schemapath> 
      </schemas> 
    </update> 

    <files folder="site"> 
      <filename>index.html</filename> 
      <filename>myforms.php</filename> 
      <filename>controller/myforms.php</filename> 
      <folder>views</folder> 
      <folder>models</folder> 
    </files> 

    <administration> 
      <!-- Administration Menu Section --> 
      <menu>My Forms!</menu> 
      <files folder="admin"> 
        <filename>index.html</filename> 
        <filename>myforms.php</filename> 
        <filename>controller.php</filename> 
        <folder>sql</folder> 
        <folder>tables</folder> 
        <folder>models</folder> 
        <folder>views</folder> 
      </files> 
    </administration> 
    </extension> 

可以有人幫忙嗎？

問題是與空間<? xml

我改成了<?xml version = "1.0"encoding = "utf-8"?>

和它的工作。感謝@Irfan
