The error tells you there's nothing to import from the location it's currently pointed at.
import-ing from a folder actually looks for a index.[d.](t|j)s file in that folder. If that file exists and it has a default export, you can assign the export a name in local scope, at import:
import stuff from '../constants'
If it contains named exports you can import them using brackets:
import { myExport } from '../constants' //or
import { myExport as localName } from '../constants'
Note: the above implies your index.ts contains something like:
export const myExport = (/* some expression */)
// you can export types, consts, functions, classes, interfaces, etc...
If you want to import all named exports from that file, use *:
import * from '../constants' // myExport is now usable
// or namespaced:
import * as local from '../constants' // (and use as local.myExport)
More examples here.
Spec here.
If you placed a file named icons.ts, having a default export, in /constants folder, your import should look like this:
import icons from '../constants/icons'
// or, for a named export
import { icons } from '../constants/icons'
