Module `Data.String.CodeUnits` was not found.

After spago install strings, psci works OK but pscid issues an error.

You might need to run spago build once, before the language server behind pscid can pick up these new modules.

@kritzcreek thanks. spago build fixes my problem. It turns out I did not install the tuples package.
