Package not found when installing with dnu install. Works with dnu restore

Question

I'm trying to dnu install Microsoft.CodeAnalysis.CSharp.Scripting 1.1.1 but it fails with Error: FindPackagesById: Microsoft.CodeAnalysis.CSharp.Scripting Response status code does not indicate success: 404 (Not Found)
Doing dnu restore with a project.json file including the same package in its dependencies list works fine:

{
  "version": "1.0.0-*",
  "description": "ScriptSharp.ScriptEngine Class Library",
  "frameworks": {
    "dotnet5.4": {
      "dependencies": {
        "Microsoft.CSharp": "4.0.1-beta-23516",
        "System.Collections": "4.0.11-beta-23516",
        "System.Linq": "4.0.1-beta-23516",
        "System.Runtime": "4.0.21-beta-23516",
        "System.Threading": "4.0.11-beta-23516"
      }
    }
  },
  "dependencies": {
    "Microsoft.CodeAnalysis.CSharp.Scripting": "1.1.1"
  }
}
