SharePoint 2013: A feature with ID has already been installed in this farm

标签：force   搬运   ready   asp.net   sha   技术   div   选项卡   share   

使用Visual Studio 2013创建一个可视web 部件，当右击项目选择"部署"时报错：

"Error occurred in deployment step ‘Add Solution‘: A feature with ID 15/3e472a61-bbc9-4242-87c7-a07e8e3fab99 has already been installed in this farm. Use the force attribute to explicitly re-install the feature."

报错原因：

完成在一个站点部署后，如果修改了项目属性中 的站点URL，打算部署到另外一个站点上，就会报此错误。

解决办法：

其实报错信息中已经提到了："Use the force attribute to explicitly re-install the feature."

如图添加"强制"属性呢？

1. 双击feature

   

2. 在"Manifest"选项卡，现在"Open in XML editor"

   

3. 在Feature节点，添加属性"AlwaysForceInstall"，完成后保存。

   

4. 重新部署，成功！
