Some of the files failed to copy during deployment of the solution.
在部署解决方案的时候遇到的一个问题：
Last Operation Result: Some of the files failed to copy during deployment of the solution.
An object of the type Microsoft.SharePoint.Administration.SPSolutionLanguagePack+DeploymentConfig named "571b0377-f761-422e-b1b4-a09ddc4f25c4" already exists under the parent Microsoft.SharePoint.Administration.SPSolutionLanguagePack named "0". Rename your object or delete the existing object. 
请高手帮我解答，谢谢！
[解决办法]
是说你这个解决方案里面的某些feature已经安装过了。用命令 Install-SPSolution -force试试：
Install-SPSolution –Identity SPSolution.wsp –WebApplication http://myspwebapp –GACDeployment -force
