Error occurred in deployment step 'Activate Features': Cannot start service SPUserCodeV4 on computer

When you first use VS2010 to deploy a sandboxed solution project (default project) , you may see this error:

Error	1	Error occurred in deployment step 'Activate Features': Cannot start service SPUserCodeV4 on computer ''.
		0	0	MySharePointProject1

Resolution:

Go to Central Administration-->select System Settings-->select Manage services on server-->Find the 'Microsoft SharePoint Foundation Sandbox Code Service' and click Start.

 

 

 

碰到这个错误了，差了半天没找到彻底的解决办法，折中一点是先在vs中deploy了，然后执行以下install-spsolution的命令，再部署一下，就部署上了。
