The above error message does not show why it is wrong and how to fix it.
Improve the error message.

The easiest way to reproduce the problem is, on Mac OS:

1. create a go module in a folder whose path includes upper case (e.g. ~/Desktop/foo)
2. create a workspace setting file using a lower case file path E.g.,

  {
  "folders": [
  	{
  		"name": "foo",
  		"path": "/Users/hakim/desktop/foo"
  	}
  ],
  }

3. open the workspace.
