looks like npm does not have permissions to modify the file system (or has create but not modify permissions) from the account running it.

Did you install node/node-red as and administrator and now running is as a non admin user?

I would check that the account running node-red has the necessary permissions for that folder `c:\users\xxxxx\.node-red\` and its sub directories .

If you need to get moving, you could try stopping node-red, opening an elevated command prompt, CD to that `c:\users\xxxxx\.node-red\` and perform the install manually `npm uninstall node-red-contrib-whatever`

As far I know, there is no permissions issue.  
This happening because even after deleting the nodes some file Ex.: serialpot.node or bindings.node is being used by node-red process.

Its will work in below scenarios:  
First:

1. Install node-red-contrib-modbus node from palette manager
2. Simply Try to uninstall the node from palette manager without using it

Second:

1. Install node-red-contrib-modbus node from palette manager
2. Drag and Connect to any server from TCP/Serial and Deploy the node-red
3. Delete the node and configuration node and Deploy the node-red
4. Restart Node-RED
5. Try to uninstall the node from palette manager

But it is not working in previous secnario.
